The company claims the Apex Pro Gen 3 is the fastest gaming keyboard in the world, featuring new magnetic switches, improved comfort, and quieter typing. We took a closer look to see what’s behind the hype and whether the premium price is justified. Friedrich Stiemer SteelSeries Apex Pro Gen 3: Design and ergonomics The SteelSeries Apex Pro Gen 3 makes an impression as soon as you unpack it. The housing consists of a robust aluminum top and a solid plastic base. Weighing around 2.42 pounds, it sits firmly on the desk. Nothing wobbles, nothing slips. A practical highlight is the magnetic palm rest, which adheres firmly to the lower edge and offers a pleasantly soft surface. It provides noticeable relief for the wrists, especially during long gaming sessions. The keyboard is full-size, including a number pad, making it ideal for anyone who writes or does office work. However, with dimensions of around 436 × 139 × 40 millimeters, it does take up a fair amount of desk space. Friedrich Stiemer The RGB lighting is remarkably even. Thanks to the new double-shot PBT keycaps, the light not only shines through the labeling, but also from the sides. These keycaps are known for their durability and abrasion resistance, offer a secure grip, and hardly discolor over time. One small disadvantage is that PBT keycaps are more expensive to manufacture and can feel slightly rougher than ABS caps. In dark rooms, this looks spectacular without being distracting. The matte finish looks high quality and hardly attracts fingerprints. Friedrich Stiemer SteelSeries Apex Pro Gen 3: Accessories In addition to the keyboard itself, the box contains a detachable, braided USB-C cable, the magnetic palm rest, and a keycap remover. Replacement caps or other extras are not included. While they aren’t essential for a premium keyboard in this class, their presence would’ve been a welcome bonus. Friedrich Stiemer SteelSeries Apex Pro Gen 3: Technology and features At the heart of the SteelSeries Apex Pro Gen 3 are the new OmniPoint 3.0 switches, manufactured by Gateron. These magnetic switches register keystrokes not mechanically, but via a Hall-effect sensor. This is a technology that works with magnetic fields to measure key travel (without contact) and with extreme precision. The switches have a linear feel with an actuating force of around 45 grams, which enables fast and consistent input. The standout feature is the per-key adjustability, allowing actuation depth to be set anywhere from an ultra-fast 0.1 mm to a full 4.0 mm. Friedrich Stiemer In practice, this means that if you need fast response times in shooters, you can set the buttons to extremely fine triggering. If you prefer precise typing, increase the depth for more typing control. The customization takes place in the SteelSeries GG software and is saved directly to the keyboard. This allows users to play with their saved profiles even without the software installed. Not all keys are equipped with the more expensive OmniPoint switches. While the main block uses them, the function row and number keys rely on classic linear SteelSeries Red switches. This is hardly noticeable in everyday use, but it’s still worth noting. There is no hot-swap function for replacing the switches. SteelSeries Apex Pro Gen 3: Performance The polling rate is 1,000 Hz. That’s solid, but not record-breaking. Some high-end keyboards now offer up to 8,000 Hz. This means that the SteelSeries Apex Pro Gen 3 registers inputs up to 1,000 times per second, which helps keep input latency very low. The keyboard also supports N-key rollover and anti-ghosting, so that multiple simultaneous keystrokes are reliably recognized. This is especially important for fast-paced games. Friedrich Stiemer One highlight is the “Rapid Trigger” function, which allows a key to reset and actuate again as soon as it is lifted slightly. In fast-paced games such as Valorant or Counter-Strike 2, this enables lightning-fast direction changes. In combination with “Dual Action Keybinds” (i.e. double assignment depending on the depth of pressure), the SteelSeries Apex Pro Gen 3 becomes a serious tool in esports. One button can perform two actions: a light press activates walking, for example, while a stronger press in the same keystroke activates sprinting. This is ideal for dynamic movements in games such as Apex Legends or Call of Duty. SteelSeries has also improved the keyboard’s acoustics. A layer of damping material now sits between the circuit board and the base. As a result, it’s much quieter than other mechanical keyboards. It produces more of a gentle “thock” instead of the typical click-clack. Friedrich Stiemer SteelSeries Apex Pro Gen 3: Software and operation Setup via the SteelSeries GG software is straightforward. Here you can set the trigger point for each button, adjust the lighting, program macros, or manage profiles. Particularly convenient are the predefined presets for well-known games such as Apex Legends, CS2, and Fortnite. Friedrich Stiemer An integrated OLED display in the top right-hand corner shows system information, volume, profiles, and incoming Discord messages. It can also be customized with personal text or a small logo. Together with the aluminum rotary wheel, the display also doubles as a hub for media control. Here you can adjust the volume, hit play or pause, and modify the lighting. However, there are no dedicated media buttons, which is a bit of a shame at this price point. SteelSeries Apex Pro Gen 3: Everyday life and gaming In everyday use, the SteelSeries Apex Pro Gen 3 proves to be a genuine all-rounder. It feels pleasantly direct and precise when typing and reacts lightning-fast in gaming situations. Shooters, in particular, benefit from the low latency. When playing Valorant and Call of Duty, keys responded practically without delay. The keyboard also impresses with long texts. The stroke remains soft, the typing noise discreet, and the palm rest ensures comfort. Anyone who has ever experienced the difference between 0.1 and four millimeters of actuation will understand how finely the typing behavior can be tuned. Friedrich Stiemer The only downside is that, with its weight and wired connection, the Apex Pro Gen 3 is clearly designed as a desktop keyboard. If you’re usually on the move, it’s better to opt for the TKL or wireless version. That version, however, comes with second-generation OmniPoint switches. Read...

A reliable indicator of the air quality in offices, classrooms, or living rooms is the CO2 content. In fresh air, the concentration of carbon dioxide is around 400 ppm. This stands for “parts per million”, in this case 400 CO2 molecules per million air molecules. Although this is only 0.04 per cent, it has a noticeable effect. Indoors, the concentration rises rapidly due to human respiration (ie. breathing). Surprisingly, during a film screening in a movie theater, CO2 levels of several thousand ppm can be quickly reached. If CO2 levels are high enough, this can lead to lack of concentration, tiredness, and headaches. A CO2 measuring station can tell you when it’s the right time to open the windows—fresh air is needed if CO2 levels reach 1500 ppm or higher. What you’ll need Firstly, you need a Raspberry Pi with a reasonably up-to-date Raspberry Pi OS. It doesn’t matter which Raspberry model you use. You also need a CO2 sensor. The MH-Z19C sensor from the Chinese manufacturer Winsen Electronics Technology is used in this article. The MH-Z19B model works in the same way. When buying, you should choose a model with pins, otherwise you will have to solder it yourself. Pins or headers are small pins that you use to connect the sensor to the Raspberry Pi. The version with headers is available on Amazon so make sure you choose that version when you buy it. Finally, you will also need jumper wires. You will need the female/female variant for the sensor. Overall, the investment is less than $40, whereas professional CO2 measuring devices cost many times more if you were to buy ready-made models. Important: To read out the sensor, the Raspberry Pi communicates via the serial interface, which is deactivated by default. To change this, use the tool raspi-config and select “Serial Port” under “Interface Options”. How the sensor works The MH-Z19C (or B) is a non-dispersive infrared sensor (NDIR). These are based on the concentration-dependent absorption of electromagnetic radiation in the infrared wavelength range. Carbon dioxide absorbs infrared radiation in a specific and measurable way. The light source transmits IR radiation through the air to be measured by the actual sensor. A filter is attached to the front which allows the absorption wavelength of the target gas to pass through. If the concentration increases, the absorption increases according to Lambert-Beer’s law and the signal decreases accordingly. The sensor determines the resulting light intensity and converts it into ppm. How to connect the sensor to the Raspberry Pi. The sensor should be viewed from the underside. Foundry Setting up the circuit To set up the circuit, first shut down the Raspberry Pi and disconnect it from the power supply. Then connect the circuit board to the sensor. You will need four jumper wires female/female, i.e. with sockets at both ends. You can see the function of each connection on the underside of the sensor. Connect pin 6 of the sensor (labelled “VCC” or “Vin”) to pin 4 on the Raspberry Pi. This is the power supply with five volts. Pin 4 is the second from the top on the right-hand side of the GPIO strip. Now connect pin “GND” (7) on the sensor to pin 6 on the Raspberry board. This is the earth wire. It is located directly under pin 4. Halfway through, continue on the other side of the sensor, which has five connections: Pin “Rx” (2) on the sensor must be connected to pin 8 on the mini computer, directly under pin 6. Finally, connect pin “Tx” (3) on the sensor to pin 10 on the Raspberry Pi, directly below pin 8. The illustration above shows the complete setup again. Finally, start the Raspberry Pi by reconnecting it to the power supply. Read out measured values The CO2 sensor is ready for use. A Python script is needed to read out the current CO2 value. Thankfully, one was developed by a Japanese developer – just for information, to explain the Github address. You install the script together with other components by opening a terminal on the Raspberry Pi and entering the following command: git clone https://github.com/UedaTakeyuki/mh-z19.git Then change to the newly created folder “~/mh-z19” and execute the installation script: ./setup.sh To determine the current CO2 value, use this command in future: sudo python -m mh_z19 You will receive a result such as “{“co2?: 3128}”. The unit is the current ppm of CO2. The measured values can be automatically displayed online and clearly show the effect of ventilation. Foundry Measured values online Always reading out the measured values manually on the Raspberry Pi is annoying and too tedious in the long run. So it’s better to display the measured values online over time. Use a free online service to access the history of the measured values via PC or smartphone. Go to monitor3.uedasoft.com and enter an e-mail address and password to log in. You will receive a “view_id”, which you do not need. Click on the menu item Elements. Make a note of the second letter combination in the list, in the example “prgrvpqg”, and set the corresponding option to Active. Click on Save to finalize the setup. Now open a terminal on the Raspberry Pi and switch back to the “mh-z19” folder. There you call the command ./setid.sh [abcdefgh] replacing the sequence of letters with the eight-digit letter combination that you have just noted. This call is used to check whether everything is working properly: sudo python -m pondslider If the word “true” appears in the bottom line of the output, then everything is OK. In order to regularly receive measured values from now on and enter them in the Monitor app, enter the command ./autostart.sh --on In the browser, you can now see how the diagram on the Monitor page grows by one measured value every five minutes. The number of measured values displayed can be set directly below using the “Settings” button. To cover ten hours, you need 120 values. With the diagram, you can see at a glance whether someone has been airing the room while you were at lunch or shopping. The graph with the measured values can also be conveniently called up with a smartphone and downloaded as a CSV file via the “Download” button in order to analyze it in Excel. After rebooting the Raspberry Pi, the measurement script restarts automatically. The concept can be expanded further. With a red LED, a suitable 330 Ohm resistor and a slightly modified Python script, a circuit can be created in which the LED lights up as soon as the measured value exceeds a specified CO2 limit value.

Price When Reviewed This value will show the geolocated pricing text for product undefined Best Pricing Today Best Prices Today: Pulsar Gaming Gears X2 CL CrazyLight Medium Wireless Retailer Price $129.95 View Deal Price comparison from over 24,000 stores worldwide Product Price Price comparison from Backmarket Best Prices Today: Check today’s prices Can you build a wireless gaming mouse that weighs less than a chicken egg? Pulsar pushes the limits with its X2 Crazylight Medium, an FPS-focused mouse that weighs just 39 grams. In this review, we’ll explore whether this featherlight wonder delivers in real-world gameplay. Pulsar X2 Crazylight Medium: Design and features The Pulsar X2 Crazylight Medium lives up to its name: the mouse only weighs around 39 grams, which is almost unbelievably light for a wireless mouse. By comparison, even ultra-light competitors like Logitech’s G Pro X Superlight 2 at around 60 grams or Razer’s Viper V3 Pro at 54 grams are about 20 grams heavier. Pulsar achieves this weight through careful internal weight savings. The result? The Pulsar X2 Crazylight Medium feels surprisingly stable despite its lightweight design. The housing neither creaks nor rattles during everyday use, and the buttons sit firmly without any annoying wobble. Friedrich Stiemer The surface is matte and smooth, which makes for a pleasant feel, but it can become a little slippery with very sweaty hands. Optional grip tapes help here. It would have been a nice touch if the manufacturer had included them by default. The shape and dimensions of the Pulsar X2 Crazylight Medium follow the popular Pulsar X2 design in a slightly shrunken version. The Medium model is around 12 centimeters long, 6.3 centimeters wide, and has a flat, symmetrical body. This allows the mouse to sit comfortably in the hand, especially for claw-grip and fingertip players. Those with medium-sized or small hands will find the low, wide shape extremely comfortable. The mouse doesn’t completely fill the hand, but it provides plenty of control for quick movements. On the other hand, the Pulsar X2 Crazylight Medium may feel a little small for larger hands. Pulsar also offers a large and a mini version. Friedrich Stiemer Pulsar X2 Crazylight Medium: High-end sensor Despite its minimalist design, Pulsar doesn’t skimp on top-level technology. At the core of the mouse is Pulsar’s exclusive XS-1 sensor, which is based on Pixart’s PAW9350. This optical sensor supports an impressive 32,000 DPI resolution, 750 IPS, and 50 G acceleration. That’s more than enough for extreme sensitivity settings or even 360-degree spin shots in shooters. Friedrich Stiemer Pulsar also offers an optional polling rate of 8000 Hz (8 kHz) via 2.4 GHz radio. By default, the mouse transmits at 1000 Hz, which is already very responsive. However, if you want every possible millisecond and have the right hardware, you can increase the polling rate up to 8000 Hz using a separately sold dongle. Currently, only a few mice like the Logitech G Pro X Superlight 2 (Lightspeed 2) support such a higher wireless rate out of the box, without replacing the receiver. In practice, the difference is only noticeable in professional esports or with high FPS displays. For most users, 1000 Hz is preferable given the potential side effects… but more on than later! Friedrich Stiemer It’s especially pleasing that Pulsar uses specially developed optical switches, which should last up to 100 million clicks and is designed to prevent double-click problems. The click feel and mouse wheel are subjectively different from mechanical switches. In the case of the Pulsar X2 Crazylight Medium, we noticed slightly less “rich” feedback, but clearly defined scroll steps. This is largely a matter of taste, though. Friedrich Stiemer Pulsar X2 Crazylight Medium: Tiny battery Speaking of side effects, the radical lightweight construction does have its drawbacks. In order to reduce the weight so drastically, Pulsar has cut corners, especially with the battery and the base of the housing. The battery is tiny. Pulsar itself claims a battery life of up to 65 hours, but this figure is probably only valid under the best conditions. In everyday use, you’ll have to charge the mouse more often than usual, especially when using high polling rates. The battery drains rapidly, sometimes after less than 10 hours of continuous use. In 1000 Hz mode, the mouse lasts a few days depending on the usage profile. In our experience, it lasted around five to seven days with average gaming time. This result is fine, but it’s significantly shorter than other competitors. Logitech’s Superlight 2, for example, lasts up to 90 hours. Friedrich Stiemer The second compromise concerns the underside. The X2 CrazyLight has a skeletonized base plate to shave off some weight. In concrete terms, this means that, in addition to the PTFE gliding feet (Pulsar supplies smaller “dot” skates in the package), there are recesses through which you can see inside–even the battery is partially exposed. While this design saves on weight, it also exposes the electronics to dust and dirt. This isn’t a major problem in a clean gaming environment, but we’d recommend not using the mouse on dirty or crumbly surfaces. In more unusual scenarios, you could theoretically push the battery through the openings, but this is unlikely to happen in normal use, unless you finger the underside of the mouse with sharp objects. Overall, we find the compromise acceptable. Most gamers will appreciate the weight advantage more than a fully closed base plate. Friedrich Stiemer Pulsar X2 Crazylight Medium: Performance In FPS use, the Pulsar X2 Crazylight Medium delivers immediate, almost weightless handling. Fast flick shots are precise, and changes in direction feel effortless thanks to the mouse’s low weight. The combination of a high-precision sensor and optical switches creates a direct, responsive gaming experience, which is especially noticeable in titles like Valorant or Counter Strike. You also benefit from the precise fine control in tactical shooters, as even slow, deliberate movements are tracked accurately. Friedrich Stiemer Away from shooters, the mouse still performs reliably. In MOBAs like League of Legends, you benefit from the fast responsiveness of the buttons, although the limited number of additional buttons may be a drawback for some folks. In action RPGs like Diablo, the mouse feels comfortable even during longer sessions thanks to its lightweight casing. The precise tracking also makes it well suited for creative tasks, such as image cropping or detailed work in graphics programs. The symmetrical shape supports smooth control, making long office or browsing sessions comfortable and effortless. Read...

However, Considering the price of less than $100, the overall package is simply impressive. You get premium-level workmanship, cutting-edge switch technology with extremely low latency and the unique freedom to combine magnetic and mechanical switches. If you’re looking for maximum performance for shooters and can do without a numpad, it’s hard to find a better offer at the moment. Price When Reviewed This value will show the geolocated pricing text for product undefined Best Pricing Today Best Prices Today: Monsgeek FUN60 Ultra Retailer Price $94.99 View Deal Price comparison from over 24,000 stores worldwide Product Price Price comparison from Backmarket Best Prices Today: Check today’s prices Can a keyboard for less than $100 really keep up with the high-end competition, which often costs twice as much? In our test, the Monsgeek FUN60 Ultra proves that it’s not only aggressively priced, but also teaches the established top dogs the how to provide great value without sacrificing performance thanks to its world-first switch technology. Friedrich Stiemer Anyone looking around the gaming peripherals market at the moment will inevitably stumble across terms such as “rapid trigger” or magnetic switches. These technologies have changed competitive gaming, but were usually an expensive investment—until now. Brands such as Wooting or Steelseries often charge $200 or more for their top models. But now, with the Monsgeek FUN60 Ultra, a challenger is entering the arena that’s shaking up this premium price structure. The manufacturer promises similar—in some cases even superior—performance for just under half the money. We put the “Ultra” in the name to the test to see if it’s justified. Friedrich Stiemer Hardly any other product on the market currently offers this flexibility, making the keyboard a true hybrid for work and play. Monsgeek FUN60 Ultra: Design When you first unpack the Monsgeek FUN60 Ultra, you immediately notice its unexpectedly high weight. At around one kilogram (2.2lbs), this compact 60 percent dwarf keyboard is significantly heavier than most of its plastic competitors. This is due to the solid, CNC-milled all-aluminium housing, which is complemented by a steel base plate. This choice of material ensures that the keyboard is extremely torsion-resistant and sits on your desk as if nailed down. The build quality is surprisingly high and conveys a real premium feel that is rarely found in this price range. Friedrich Stiemer The design of the Monsgeek FUN60 Ultra is minimalist and straightforward, which really brings out the powerful RGB lighting, especially in the white color version. The only curious detail is the eyelet for a carrying strap on the left-hand side of the case, which is probably more of a visual gimmick than anything. However, we take a more critical view of the lack of adjustable feet. You have to make do with the fixed typing angle of six to seven degrees, which we found to be ergonomically pleasant in the test, but still restricts flexibility. However, the engineers made a real design faux pas with the switch for the operating modes. This is hidden under the cap lock button, so you actually have to remove the button cap every time you want to switch between cable and wireless. This is an unnecessarily cumbersome solution in everyday use. Friedrich Stiemer Monsgeek FUN60 Ultra: Typing The so-called “Akko Glare Magnetic Switches” came with our test sample. As these switches are already pre-lubricated at the factory, they glide down smoothly and without any noticeable scratching. Acoustically, the Monsgeek FUN60 Ultra is absolutely surprising, as it’s unbelievably quiet in operation despite the metal housing. Thanks to extensive internal insulation, the result is a rich, muffled sound that is often referred to as “thocky” in enthusiast circles. You won’t find any annoying metallic echoes or rattling of the large keys here, which is why the input device is also suitable for office environments, provided you can do without the numeric keypad. Friedrich Stiemer Haptically, you should note that the circuit board is firmly screwed into the housing, which is known as the tray-mount design. This makes for a very direct, precise touch, but with less give than on spring-mounted keyboards. If you prefer a very soft touch, you might find the Monsgeek FUN60 Ultra a little stiff. The PBT plastic keycaps showed a small shortcoming in the long-term test though: Although these are generally robust, the heavily used WASD keys tended to develop a shiny surface relatively quickly. However, as the keyboard follows the standard layout, you can easily replace the caps with a set of your choice. Friedrich Stiemer Monsgeek FUN60 Ultra: TMR technology and the “MagMech” feature Technically, the Monsgeek FUN60 Ultra clearly stands out from the crowd. While most current high-end models rely on Hall-effect sensors, TMR (Tunnel Magneto Resistance) technology is used here. This technology allows an even finer signal resolution and theoretically saves power. In practice, this means that you can set the trigger point of each individual button extremely granularly between 0.1 millimetres and 3.4 millimetres. Particularly impressive is the rapid trigger function, which means that the button does not have to return to its original position to be triggered again. A minimal stroke of just 0.01 millimetres is enough for the Monsgeek FUN60 Ultra to register a new command. In fast-paced shooters such as Valorant or Counter-Strike 2, this enables movement maneuvers and firing sequences at a speed that would hardly be possible with conventional mechanical keyboards. Friedrich Stiemer An absolutely unique feature is the so-called “MagMech” functionality. The TMR version of the Monsgeek FUN60 Ultra is cross-compatible, which means that you can mix magnetic switches and classic mechanical switches (5-pin) on the same board. You therefore have the option of equipping only the WASD keys relevant for gaming with the fast magnetic switches and using your favourite tactile mechanical switches for the rest of the keyboard. Hardly any other product on the market currently offers this flexibility, making the keyboard a true hybrid for work and play. Friedrich Stiemer Connectivity and battery life The name “Ultra”, as you’d expect, indicates a variety of connectivity options, as the keyboard can be operated via USB-C cable, Bluetooth 5.0, and fast 2.4 GHz radio. The wireless performance is exemplary, as the Monsgeek FUN60 Ultra achieves a sampling rate of up to 8,000 hertz in 2.4 GHz mode. This means that it responds wirelessly just as quickly as a wired keyboard, and even professionals shouldn’t notice any difference in latency. Friedrich Stiemer However, this extreme performance takes its toll on energy consumption: If you use the full 8,000Hz polling rate and activate the RGB lighting at the same time, the 4000 mAh battery runs out of breath very quickly. In our tests, the Monsgeek FUN60 Ultra often only lasted a few hours in this high-performance mode. If you want to game wirelessly with maximum performance, you’ll have to charge the keyboard almost every day. In Bluetooth mode or with dimmed lighting, on the other hand, the battery lasts for days, which is why we recommend only using the 8K mode for competitive gaming sessions. Friedrich Stiemer Monsgeek FUN60 Ultra: Software The Monsgeek FUN60 Ultra is configured using driver-based software that runs in the browser but still requires installation in the background. The range of functions is extensive and extends from the creation of complex macros to “dynamic keystrokes”, in which different pressure depths trigger different actions. Features such as SOCD, i.e. the prioritization of opposing directional inputs, are also available. However, the user interface is not yet fully developed making the menu navigation confusing at times. Although the manufacturer has already fixed many initial bugs with firmware updates, beginners will have to be prepared for a certain learning curve in order to utilize the full potential of the Monsgeek FUN60 Ultra.

That said, the 8K polling eats up a lot of power and the price tag might be too steep for some. Price When Reviewed This value will show the geolocated pricing text for product undefined Best Pricing Today Best Prices Today: Asus ROG Harpe II Ace Retailer Price $146.99 View Deal Price comparison from over 24,000 stores worldwide Product Price Price comparison from Backmarket Best Prices Today: Check today’s prices With the ROG Harpe II Ace, Asus delivers a wireless esports designed for maximum performance and lightness. Weighing just 28 grams, it features 8,000 Hz wireless polling and the new ROG AimPoint Pro sensor with 42,000 DPI. But is it really worth the $169.99 price point? Let’s take a closer look at this top-tier model. Asus ROG Harpe II ACE: Design and ergonomics The mouse’s lightweight form factor is obvious as soon as you unpack it. At just 48 grams, the Asus ROG Harpe II Ace is one of the lightest gaming mice ever–lighter than many honeycomb-designed models. Yet it remains stable and torsion-resistant, with nothing rattling or creaking. Friedrich Stiemer The housing is symmetrical but not completely ambidextrous. With two side buttons on the left, the mouse is clearly aimed at right-handed users. Its shape was developed with esports pros in mind, including Valorant player Maximilian ‘Demon1’ Mazanov. It sits flat in the hand and is ideal for claw and fingertip grips. In fast-paced shooters like CS2 or Valorant, it reacts instantly, gliding smoothly across the pad without causing fatigue. Friedrich Stiemer The Asus ROG Harpe II Ace’s bio-based nylon surface feels soft, though this is a matter of taste. Some testers praise the smooth finish while others note the visible fingerprints. Overall, the mouse leaves a very high-quality impression. Asus ROG Harpe II ACE: Technology and features The centerpiece of the Asus ROG Harpe II Ace is the ROG AimPoint Pro sensor, which supports up to 42,000 DPI. While that figure might seem like marketing hype, what really matters is precision and the sensor delivers where it matters. Movements are executed without noticeable delay, and even fine aiming corrections are spot on. In our testing, the cursor stayed stable during fast flicks, a clear advantage for esports players. Friedrich Stiemer Another highlight is the 8,000 Hz polling rate, which Asus also enables wirelessly, transmitting eight times more position data per second than standard mice. In practice, aiming and tracking feel noticeably smoother. However, to conserve battery, you should only activate that feature when necessary. At 8,000 Hz, runtime drops to around 15 hours. At 1,000 Hz, the Asus ROG Harpe II Ace lasts for over 100 hours. It charges via USB-C and just a few minutes on the cable is enough for several hours of gaming, so you can keep playing even when the battery is empty. Asus ROG Harpe II ACE: Clicks, buttons, and operation Asus uses durable ROG microswitches that deliver a clean, crisp click. The main keys respond immediately and offer precise feedback with no bouncing. The click feel stayed consistent even after several days of intensive use. The mouse wheel clicks precisely, though it doesn’t tilt horizontally or spin freely. Perfectly fine for gaming, though a bit spartan for productivity. It offers five buttons plus a DPI switch. That’s enough for shooters, but limited for MMO gamers. Friedrich Stiemer The zone mode of the Asus ROG Harpe II Ace is activated via a shortcut using both side DPI buttons. The mouse will then automatically optimize all parameters for competition, turning off RGB lighting and pushing performance to the max. It’s a clever little shortcut for competitive players. Asus ROG Harpe II ACE: Software and configuration Instead of relying on the often-criticized Armoury Crate software, Asus uses the Gear Link web app. DPI levels, key assignments, and lighting can be adjusted directly in the browser, no installation required. The interface is clear, responsive, and works on any device. It saves system resources and makes everyday use simpler. The only downside? No onboard memory. Profiles aren’t stored permanently, so using the mouse on multiple PCs requires reloading the settings through the web interface. Friedrich Stiemer Asus ROG Harpe II ACE: Practice and performance In everyday use, the Asus ROG Harpe II Ace impresses with butter-soft tracking, lightning-fast responsiveness, and excellent control. In shooters such as Apex Legends or Call of Duty, the crosshairs remain stable even during hectic movements. The low weight noticeably reduces the strain on the wrist and forearm, which is ideal for long sessions. The mouse also performs well in office use, although the simple scroll wheel and limited buttons restrict the range of functions. The Bluetooth connection is stable, but competitive gamers will prefer the 2.4 GHz dongle. Asus ROG Harpe II ACE: Scope of delivery The Asus ROG Harpe II Ace comes with a flexible USB-C cable, a USB-C to USB-A adapter, replacement skates, high-quality grip tapes, and a set of stickers. Professionals are thus well equipped and gain extra grip. A carrying bag, however, would have perfectly rounded out the package, especially if you’re the type of person that travels a bunch.

This is the second generation of the popular Arctis Nova 7, with Steelseries building on proven strengths and making targeted improvements. Even on paper, the technical specifications are impressive: 40-millimetre neodymium drivers, dual wireless (2.4GHz dongle and Bluetooth 5.3) with simultaneous function, over 50 hours of battery life, broad platform support, and a comfort-oriented design. This review clarifies whether the Nova 7 Gen 2 can earn these praises in the practical test, and where its weaknesses lie. Design and wearing comfort On the outside, Steelseries remains true to its line: The Arctis Nova 7 Gen 2 relies on the classic Steelseries design with matte-black plastic and a sleek look. The metal frame in the headband provides stability, while an elasticated spring band (in the style of ski goggles) distributes the contact pressure. This combination — Steelseries calls it the “ComfortMax” system — ensures a first-class fit without pressure points. In the test, the wearing comfort actually proves to be outstanding: Several hours of continuous use are no problem, the headset remains comfortable and secure on the head. Weighing around 11.4 ounces (325 grams), it is not ultra-light, but thanks to the good weight distribution it does not feel too heavy. Friedrich Stiemer The ear pads are made from a hybrid of breathable fabric and artificial leather. This gives them a soft fit and allows some air to reach the ears, while the artificial leather on the inside minimizes sound leaks. In practice, external noise is passively dampened, although not completely shielded, as the partially open design is noticeable here. After very long sessions, however, the ear areas can get a little warm. But overall, the positive impression of a well thought-out, comfortable headset prevails. Friedrich Stiemer The build quality is also of a high standard: Nothing wobbles or creaks, the adjustment mechanism (extendable ear cup holders and three adjustment points for the spring band) appears durable and designed for a wide range of head sizes. Overall, the Steelseries Arctis Nova 7 Gen 2 feels robust and high-quality — ideal for daily gaming use. However, there is one small design criticism: The USB-C dongle supplied is unusually wide at 2.11 inches (approx. 53.8 millimeters) and can block neighboring USB ports. Although Steelseries supplies a short USB extension cable, a slimmer, longer dongle would have been more practical. Apart from this detail, the Steelseries Arctis Nova 7 Gen 2 impresses across the board with its simplicity, excellent ergonomics, and well thought-out design. Features and connectivity In terms of functions and connectivity options, the Steelseries Arctis Nova 7 Gen 2 packs a punch. The headset can be paired wirelessly via a 2.4GHz wireless dongle and in parallel via Bluetooth, even simultaneously to mix two audio sources. The USB-C dongle ensures a latency-free connection to PC, Mac, Playstation 5, and Nintendo Switch (both in the dock and mobile via USB-C). A slide switch on the dongle enables the special Xbox mode for the Xbox Series X/S, as Microsoft’s consoles require a proprietary wireless protocol. Important: Steelseries offers the Arctis Nova 7 Gen 2 in different versions: Nova 7P (PlayStation/PC) and Nova 7X (Xbox all others). The hardware is identical, but only the X version is fully compatible with the Xbox. So if you choose the Arctis Nova 7X version, you can in fact cover all platforms. In tests, the wireless connection proved to be very stable and long enough range to take a break in the next room without losing contact. In addition to Bluetooth, mobile devices also have the option of using the USB-C dongle on smartphones or tablets, for example via an adapter. Here, however, we have observed that a dongle connection plugged directly into the mobile phone can sometimes have a brief loss of connection when moving. In such cases, Bluetooth pairing is the more convenient choice when travelling. Speaking of Bluetooth: This wireless method only uses the SBC codec, which is okay for listening to music, but can lead to noticeable delays when gaming or watching videos. The 2.4GHz mode is therefore clearly recommended for gaming, as it has virtually no latency. Friedrich Stiemer In addition to wireless, wired operation is also possible: the headset has a 3.5 millimeter jack socket to connect it to a PC, controller, or handheld in the classic analog way. This even extends compatibility to older devices (e.g. for the Nintendo Switch Lite or some gaming handhelds) and serves as an emergency solution in the event of battery failure. The controls on the headset are arranged in a user-friendly way: The power button, a dedicated Bluetooth button and a wheel for the chat-game audio balance (chat mix) are located on the right ear cup: A blessing in multiplayer to be able to finely balance voice chat and game sound at all times. On the left is the volume control knob and a clearly perceptible microphone mute button. The buttons and wheels provide clear haptic feedback so that they can be operated intuitively even in the middle of a game. The Steelseries Arctis Nova 7 Gen 2 does not have active noise cancellation (ANC), but this is not unusual in this price range of less than $200 — most gaming headsets at this price do not offer ANC anyway. The passive isolation provided by the padding is average: Everyday noises such as keyboard clacking or quiet background chatter are noticeably muffled, but still penetrate somewhat at higher volumes. Overall, however, the features of the Steelseries Arctis Nova 7 Gen 2 are impressively comprehensive: Multi-platform support, simultaneous connections, and analog fallback option make the gaming headset an extremely flexible companion. In fact, the Arctis model works with practically everything, from PCs to consoles and smartphones, making it a true all-rounder. Friedrich Stiemer The dual wireless function is particularly noteworthy: In the test, simultaneous playback from PC/console and mobile phone worked smoothly and without dropouts. For example, you can be in a Discord chat on your mobile phone via Bluetooth while gaming on the PlayStation, or take a call while gaming on the PC. Incoming calls are handled cleverly: If a call comes in via the mobile phone, the headset microphone is automatically muted for the game chat so that you can make the call undisturbed. When you hang up, it switches back to the game chat. This seamless integration of both audio channels is extremely practical in everyday life. Sound quality The sound quality of the Steelseries Arctis Nova 7 Gen 2 is geared towards the needs of demanding gamers without compromising on all-round qualities. The 40-millimeter speaker drivers deliver precise, detailed sound across the entire frequency spectrum. Steelseries clearly emphasizes clarity in the mids and highs, which allows fine details such as footsteps or directional noises to stand out clearly. In fact, the Steelseries Arctis Nova 7 Gen 2 shines in the test when it comes to spatial localization: In shooters and action games, it was possible to make out exactly from which direction opponents were approaching — a tactical advantage that not every headset in this class offers. This is supported by the virtual surround function (Steelseries Sonar Spatial Audio on the PC and Tempest 3D Audio on the PS5), which makes the sound image even wider and more immersive if desired. In single-player games, the surround mode significantly enhances the atmosphere. In competitive games, on the other hand, we mostly used the stereo mode, as the localization is precise and without artificial effects — the Arctis Nova 7 already delivers excellent positioning information in stereo. As delivered, the sound tuning is slightly fun-orientated: The bass has plenty of body and pressure, while the upper treble sounds slightly over-sharpened. This leads to a powerful rumble during explosions, for example, but can sometimes be perceived as a little too sharp with very high tones. Voices and important game sounds in the mid-range come through clearly and dominate the action, giving the headset its “tactical” sound. Friedrich Stiemer Our music tests showed that the Steelseries Arctis Nova 7 Gen 2 is also suitable for everyday multimedia: Songs sound dynamic and balanced, albeit not at hi-fi level, as the deepest bass and fine detail in the highest registers reach the limits of gaming tuning. Sound enthusiasts may note that the fine-tuning ex works is not completely neutral: For example, certain treble ranges are slightly overemphasized and could be a little tiring for sensitive ears in the long term. However, this is where the great strength of the Steelseries software comes into its own: The parametric equalizer in the Sonar app allows the sound image to be corrected and optimized as desired. We were able to tame the slightly sharp treble and fine-tune the bass with just a few movements of the EQ controls. The Steelseries Arctis Nova 7 Gen 2 then sounded very balanced. Steelseries also provides over 200 predefined EQ profiles, customized for various games, from Call of Duty to Counter-Strike 2, which can be loaded with a click. In the test, some of these presets actually brought audible improvements for specific scenarios, such as clearer footsteps in shooters or more powerful effects in action adventures. In short, the Steelseries Arctis Nova 7 Gen 2 delivers a strong audio performance out of the box, especially for gaming. If you want to further refine the sound, you have all the options with the software tools. In this price range, the Arctis Nova 7 Gen 2 is right at the top. More expensive models such as the Steelseries Arctis Nova Pro or the Elite offer even finer hi-res sound, but also cost many times more. For a $200 headset, the sound quality of the Steelseries Arctis Nova 7 Gen 2 is absolutely convincing and left hardly anything to be desired in everyday gaming. Microphone and voice chat Steelseries equips the Arctis Nova 7 Gen 2 with the tried-and-tested “ClearCast Gen2” boom arm microphone. This can be retracted into the left ear cup and fits seamlessly into the design when retracted — ideal if you want to use the headset as normal headphones when travelling. The microphone can be flexibly bent into position and is simply pulled out for use. However, it is not detachable; it always remains attached to the headset. The LED indicators are practical: A small red LED on the tip of the microphone signals that the microphone is muted, and a status LED also indicates the connection mode. Friedrich Stiemer In voice chat practice, the Steelseries Arctis Nova 7 Gen 2 delivers solid intelligibility. Voices are transmitted clearly and background noise is effectively suppressed. According to Steelseries, this should be up to 25 decibels thanks to AI noise cancelling. In our Discord rounds, our fellow players confirmed that our voice came through clearly and without loud background noise. Nevertheless, we have to say: In terms of sound, the microphone is only mid-range. Our criticism is that the voice transmission is somewhat unnatural and nasal, as if the voice is filtered slightly mechanically or tinny. This is a typical phenomenon with many gaming headsets that cut frequencies in favor of clarity. As a result, the Steelseries Arctis Nova 7 Gen 2 never sounds as full or natural as an external microphone. However, the result is absolutely fine for normal voice chat. However, anyone who values particularly warm or authentic voice transmission (e.g. for streaming) will see the average microphone as a weak point. In a direct comparison with some competitor headsets in this class, the ClearCast microphone performs slightly worse — the microphone on the HyperX Cloud III S Wireless or the Razer Blackshark V3 Pro, for example, sound a little fuller. On a positive note, however, the microphone of the Steelseries Arctis Nova 7 Gen 2 is not overly sensitive: Loud ambient noises or keyboard clatter are rarely transmitted. The headset also has microphone monitoring — you can hear yourself slightly on your ear — which protects you from unconsciously speaking loudly. Tip: The microphone should actually be used extended for optimum results. Although it is technically possible to speak when the headset is inserted (it is then not automatically muted), the quality suffers significantly: The voice is barely captured and sounds muffled. You therefore have to pull out the headband to remain intelligible. This is not a problem in everyday use, as the flexible arm can be positioned easily. In particularly quiet situations, we also notice a slight background noise or white noise from the microphone and hope for firmware optimizations here. On our test device, a slight background noise was only audible when no other sounds were playing; in gaming mode, it was drowned out by the sound. Overall, the Steelseries Arctis Nova 7 Gen 2 delivers a functional microphone that is absolutely sufficient for game chat, VoIP telephony and most applications, but is not a highlight. If you’re looking for absolute top microphone quality, you’ll either have to resort to significantly more expensive headsets or consider a separate microphone. For everyone else, the level offered is acceptable. Battery life and charging functions A big plus of the Steelseries Arctis Nova 7 Gen 2 is the significantly longer battery life. Steelseries has increased the capacity by around 40 percent compared to its predecessor and now promises an impressive usage time of up to 54 hours in 2.4GHz mode. In Bluetooth-only mode, the battery is expected to last around 42 hours, and even when using wireless and Bluetooth at the same time, the battery still lasts around 38 hours. In practice, over 50 hours of battery life means that the headset only needs to be charged once or twice a month with moderate daily use, making it a real long runner. Our test period extended over several days of intensive gaming (six to eight hours per day) and we didn’t actually have to charge the Steelseries Arctis Nova 7 Gen 2 in between within a week. The battery status is displayed via the software and an LED display on the device, and the headset emits warning tones when the battery is low. However, we found the series of warning tones a little intrusive when the battery is low: three loud warning tones sound every two minutes or so, which can be annoying in the long run. Nevertheless, an empty battery is unlikely to come as a complete surprise, as the Steelseries Arctis Nova 7 Gen 2 is really long-lasting. And even if you forget about it, help is at hand: Thanks to the quick-charging function, 15 minutes on the cable is enough to give you around six hours of playing time. The battery charges fully in around one and a half hours. Friedrich Stiemer Another practical feature is that you can continue to use the headset while it is charging. Simply connect the USB-C cable and it will charge in the background without interrupting the game. This means that spontaneous gaming sessions are never jeopardized. Overall, the Steelseries Arctis Nova 7 Gen 2 ranks at the top of the wireless headset range in terms of battery life. Only a few models (such as the HyperX Cloud III S Wireless with over 100 hours) run even longer, but over 50 hours is already more than enough for long gaming nights. Software and extras The GG software, including Sonar, is a real asset for Steelseries. This software suite integrates hardware and software in an exemplary manner and offers a wide range of customization options. On the PC, you can use Steelseries GG to install firmware updates for the headset, but above all you can configure the sound extensively: A parametric 10-band equalizer, various predefined sound profiles for different game genres, sliders for game/chat mix, volume, microphone level, and sidetone (monitoring) — all of this is clearly available. The user interface is designed to be beginner-friendly; if you don’t want to familiarize yourself in depth, simply select one of the many presets and get a suitable sound without any effort. Advanced users will be delighted with the ability to fine-tune every sound detail from treble filter to bass boost. Thanks to the integrated sonar technology, we were actually able to tease a lot out of the headset during the test. Steelseries Sonar is regarded by connoisseurs as one of the best headset apps on the market, and our experience confirms this: The EQ function and the continuously updated gaming presets (over 260 profiles according to the manufacturer) are unique and very useful. Remarkable: Since the second generation, the Steelseries Arctis Nova 7 Gen 2 now also supports the Arctis smartphone app. This allows console gamers or mobile gamers to make some settings conveniently on their mobile phones. For example, the app can be used to select EQ presets, adjust the sound mix, or control lighting (if available). The parametric fine-tuning is reserved for the PC software, but basic profiles can also be changed on the move. In the test, the app pairing worked straight away; it is also pleasing that no compulsory registration is required to use the app or PC software. Friedrich Stiemer Overall, Steelseries emphasises its premium claim with the software: The possibilities go far beyond what standard drivers offer. Only those who absolutely don’t like additional software on the PC may be overwhelmed: The Sonar app can seem complex at first, but it’s worth spending 15 to 30 minutes familiarizing yourself with it. For most gamers, the software integration is a great added value that sets the Steelseries Arctis Nova 7 Gen 2 apart from more simply equipped competitor models.
