Features
  • 48.4g. Optimized lightweight. Refined with Fnatic pros.

    Refined to 48.4g (approx.) based on pro feedback, INZONE Mouse-A helps reduce fatigue and sharpen control over extended play. Its polyamide frame, engineered with hollow glass microspheres to reduce weight, delivers a stable feel with minimal flex.

  • Form for the grip of the game

    Shaped with the insight of Fnatic’s elite players, INZONE Mouse-A is built for optimal control and stability. Its contoured design supports high-speed maneuvers and repeat clicks, empowering focused play and minimal strain across competitive sessions.

  • 3950IZ sensor. Fast, precise, relentless.

    Our custom 3950IZ sensor delivers up to 30,000 dots-per-inch (DPI) of tracking resolution, dramatic linear accelerations with up to 70G of force, and 750 inches-per-second (IPS) imaging for wide sweeps and pinpoint accuracy even at elite-level speeds.

  • 8000Hz polling for ultra-fast input response

    INZONE Mouse-A supports custom polling from 500 to 8000Hz, communicating via its USB dongle for stable, low-latency performance. High-speed transmission reduces input lag and enables sharper tracking—fine-tuned for peak control in competitive play.

  • Stable 8000Hz performance with INZONE tuning

    The 3950IZ sensor delivers steadier 8000Hz polling over time, unlike other leading competitors—such as X and Y in the comparison table—which show sharp drops mid-game. INZONE holds strong, session after session.

  • Light-speed clicks with optical switch

    The optical switch reacts on light, not friction—delivering faster input and smoother keystrokes. Built for long-term reliability, it offers precise, consistent control from the first press to the final round.

  • Wheel

    Designed with Fnatic pros, the scroll wheel delivers tactile feedback on every notch, so you feel each scroll and stay in rhythm with play.

  • Side button

    Built with a reinforced design, the side button resists unwanted flex, staying solid under pressure even with firm clicks.

  • Back button

    The back button toggles power with a long press, or cycles through up to four customisable profiles. Versatile control, all in one.

  • Fast-charging, up to 90-hour battery life

    Please update battery life bullet to say: With up to 90 hours of use and a 5-minute quick charge delivers up to an extra 10 hours for play, the INZONE Mouse-A keeps you in the game longer

  • Fine-tune with the INZONE Hub

    The INZONE Hub puts full customization at your fingertips. Adjust DPI, polling rate, button functions, and more—then save it all to game-specific profiles for quick access. Available in both software and web versions.

    Sony's INZONE Mouse-A delivers a WIN!

    This Sony INZONE Mouse-A Ultra-Lightweight Optical Switch Wireless 8K Gaming Mouse is so light at approx. 48.4g, that it's almost unbelievable. I have never used a mouse that was this lightweight before. As one would think, it can be moved incredibly quickly. I won't bore you with the specifications, but the sensor on this mouse leads to amazing resolution and tracking speed and that leads to incredible precision. Precision is what matters to me. The resolution DPI, polling rate and the super easy to click 5 mouse buttons, including the scroll button, can all be customized with the use of Sony's INZONE Hub software. Adjustments are made either via their PC app or the web and you can save up to 4 profiles. The mouse comes with a dongle and a USB-C to USB-A cable that is used to connect the dongle to your PC and it is also used to charge the mouse. This type of dongle is a change for me because instead of just popping it into a USB slot and forgetting about it, it is a small type of fob that needs to remain plugged into your PC and near your mouse in order for the mouse to work. It also comes with an extra set of "feet" for the bottom of the mouse that aid in the smoothness of the travel and a couple of INZONE stickers. Sony claims this mouse provides 90 hours of wireless use after fully charging and with a quick 5-10 minute charge, it provides 10 hours of play. If you prefer to play wired, you can use a USB-C connection. Wired play reduces the latency to zero, but I'd rather use it wirelessly. Using the INZONE Hub app, I am able to check the remaining charge. The design of the Sony Mouse-A was conceived with the help of top game players from Fnatic, and they know what they need and want to win. My only issue with the shape of the mouse is that it is a tad too large for my hand and I find it difficult to reach the forward side button. Otherwise, I am loving it. The ease of use, the speed and the accuracy are absolutely fantastic. Overall, I am thrilled with this Sony INZONE Mouse-A Ultra-Lightweight Optical Switch Wireless 8K Gaming Mouse. I actually feel that the super light weight of this mouse enables longer play time. My hand doesn't get tired as quickly as it did before getting this. I am thoroughly enjoying this mouse - it's light weight, provides a way for me to customize it to my personal play style, and it is speedy and extremely accurate. I do wish it would also come in a slightly smaller size, but that is my only complaint! This is an unbelievable mouse and I highly recommend it!

    Super lightweight yet solid and precise

    I have been using the Sony INZONE Mouse-A for almost a week now and it is quite impressive. First thing you’ll notice is how light it is at just over 48 grams or 1.7 ounces. For some devices you could associate light-weight for cheaply built but that is NOT the case for this Sony mouse. It is solidly built of the highest quality materials with a polyamide frame and it performs equally as solid. It glides ever so smoothly on any surface and it even comes with a spare set of glides. In terms of size, it’s probably most comfortable for medium to large hands which worked great for me. The high-end hardware components used in this mouse make it great for hard core gamers, thanks to the Sony 3950IZ sensor capable of 30,000 DPI resolution and 70G acceleration. The 8,000Hz polling rate enables nearly instant response time giving gamers an unprecedented advantage. I would also add, this mouse is also great for CAD and graphics design apps, thanks to its super-high resolution and pixel-perfect precision. I used it for some detailed architectural drawings and it was amazingly accurate. Installation was a breeze. I first used it with the USB-A to USB-C cable provided to charge its built-in long life lithium battery. Once it was fully charged, I used the same USB cable to connect the 2.4 GHz wireless dongle it came with. If you want to take advantage of all the advanced customization settings, you will have to install the Sony INZONE Hub PC software or very conveniently use the INZONE Hub for Web version which works just as well. All buttons functions can be customized in addition to the Sensitivity DPI, Polling Rate and Lift-off distance. Unlike any other mouse I’ve ever used before, the SONY INZONE Mouse-A has 4 profiles you can save different settings for and those settings will actually be saved in the mouse’s memory to seamlessly carry over with your mouse to multiple devices. I am now using this mouse all day on my work computer and after hours and on weekends on my gaming desktop and would highly recommend it to those who can afford it, since it is quite pricey for a mouse, but once again this is no ordinary mouse.

    Lightweight and high precision gaming mouse

    The Sony INZONE G500 is a very lightweight, customizable and very precise wireless mouse. You can also use it wired if you wish. It is ideal for gaming (as expected from its product description) and well, in my case, it also comes in handy for everyday use. One downside if you want to enjoy the wireless connectivity is that you’d need to use the Sony proprietary wireless adapter that comes in the package, connect it to the host computer, and then be able to use the mouse. This mouse doesn’t support Bluetooth, which I guess is understandable if you want to provide your own wireless technology. In addition, this mouse doesn’t have those “tens” of buttons everywhere that other gaming mice provide, so it is ideal if you are looking for simplicity in your gaming, just take this one. I would give this mouse a 5-star rating but there are a couple of things that get in the way of a perfect score. I address some of them later in the review. >> Reliability So far, I’ve been very pleased with the Sony INZONE Mouse A G500. I’ve been using it for gaming, but more for regular work (which is what I do most of the time anyways). No complaints while using it. The connectivity and signal power is wonderful, I placed the wireless adapter several feet away, and I can still use the mouse with no issues. I’d highly recommend it just for that “feature”. I have at least one other gaming mouse with Bluetooth connectivity, and I get the sense that this one, the Sony Mouse A, is more reliable connection/signal-wise. The device is easy to customize to your needs. Need to move faster? Need to move with more precision for that graphics detail? Need to assign functions to your buttons? You can do all of that and much more. Nee >> Power on/off indicators Why care about power indicators? Well, this device doesn’t really have any light source/indicator on it to let you know whether it is on/off. You’d need to: - Move the mouse and if you see the cursor moving on the screen, then it is on. - Press the power button located at the bottom of the mouse and if it is on you’d see a light. - Look at the wireless receiver, if the light is on, then the mouse is on. However, it could be that the receiver light is off if there was no mouse activity, so you’d still need to move the mouse and see if the receiver light stays on. Another aspect I don’t like too much is that you need to press and hold the power button for a few seconds for the mouse to turn on or off. Perhaps an on and an off position would have been better for this device. >> Battery Initially, I wasn’t sure the battery life was decent, since I recall I used it for a couple of days in wireless mode, without turning the Sony Mouse A off, and it ran out of battery after those couple of days. The second charge took about the same as the first one, about 15 minutes (how to know if it is charging? The front light in the mouse becomes amber). Now, it’s been a few days on that second charge, and the mouse has been running fine with the Hub App showing still 100% battery, which seems strange (or incorrect). The only inconvenience I see is that it is not very predictable when to recharge the mouse. Well, you do it when the mouse dies of course. Perhaps there are early signals, such as amber or red light on the mouse, but I haven’t seen anything like that yet. >> INZONE Hub App You’d need to install the INZONE Hub App if you want to have access to the Sony INZONE Mouse A specific settings, and if you want to have profiles with settings customized for different tasks/scenarios. The App allows up to 4 profiles, and in my case for my main gaming machine, I have three profiles configured: Work, Game, and Graphics, which serves me well for all my main tasks. There are two groups of settings: 1) performance settings, to adjust sensitivity and others, and 2) Allocation settings, where you can decide what each button in the mouse can do under a certain profile. The App seems to have all what is needed to configure the mouse; however, there is a Battery indicator, that I am not sure provides the right number. It’s been consistently showing 100% even when my mouse was about to run out of juice. >> INZONE Web App Now, if you don’t want to install the Desktop App, you can use the Web App by going to https://inzone-hub-for-web.sony.net/, which I did after I installed the Hub Desktop App and to my surprise, after connecting the Mouse A to the Web App, all my profiles and settings were available there! So, I guess both use the same location to store the data. One important thing about the Web App, once the mouse is connected to the host computer, in order for the Web App to access the configuration, you do need to click on the “Connect Device” option at the top left area in the Web App and select the mouse.

    Light, comfortable and adjustable

    This is one of the lightest mouses I have every used, the curve is great for long use. I do wish it was a bit wider as when using it portion of my hand sits off the mouse. I used it for 8 hour plus days and my wrists were never fatigued; this was the same for gaming. The mouse can be used wirelessly or wired and I have been using it for over 4 days and the battery life is excellent. The mouse works flawlessly on all surfaces and the reaction/response times are excellent. Sony mentions it was designed with Fnatic and you can tell as all clicks register and precision is excellent for all types of gaming sessions. Response times are crucial for competitive gaming and this mouse is perfect for competitive gaming. The INZONE app is nicely laid out with tons of adjustments you can do to make the mouse more personal. The configurations can be done by downloading the program or just through the web portal (no sign in required). All buttons and the scroll wheel can be changed to fine tune your experience, one of the best adjustments for me personally was using the scroll wheel as a media play/pause button. The wireless transmitter allows you to keep your mouse setting no matter what computer you use. Not only can you keep your profile settings, but you can change profiles by simply by holding the power button below the mouse and back button. One of my favorite adjustments was being able to use the scroll wheel click as a start/stop for media. I have a thunderbolt dock and 4 laptops and no matter which one I use all my settings carry forward even without downloading Inzone software or using the web portal. This is huge as you’re not having to download a app when changing machines and let’s be honest no one wants to download any more programs/apps. Sony has done a great job engineering a mouse that can be used for gaming and everyday use. The mouse feels great in hand and is perfect for gamers who want precise control while gaming and comfortable for long office hour/general use.

    Next Level Mouse

    The Sony INZONE Mouse-A is positioned as a pro level gaming mouse that was developed in collaboration with Fnatic that comes in at just 48.4 g making it super lightweight. That message is a tall order, so I was excited to put his mouse through its pace and see does it live up to the hype. Sony says this mouse was designed to deliver speed and lasting comfort for competitive gamers. So, to test this out I put in over 75+hours of gameplay in COD, APEX and Fortnite. MOUSE The mouse design comes in a comfortable form factor that ergonomically matches my hand curvature when I place my hand on it. It’s small enough yet wide enough where there was zero discomfort in its smooth shape. It can be used via cord or its 2.4Ghz wireless connection via the USB type-A to Type-C. The mouse comes with a Sony 3950IZ sensor that has a resolution ranging from 100-30000 DPI which can be adjusted in increments and up to 750 IPS tracking speed. This can all be fine tuned in the INZONE HUB. Using Mouse testing software, I was able to test the polling, DPI and mouse latency. Latency: Wireless 2.4 Ghz= Averaged 1.12-1.18ms Wired=1.6-1.8ms DPI: I conduct 35K moves Wireless 2.4 Ghz Average: 98% Wired Average: 96.9% Cursor Drift was .5mm when repositioning the mouse on screen in boundaries. Battery Life Sony states 90 hrs. of battery life on a single charge, I clocked in just over 82 hours total usage and had 10% of battery life remaining which shows a very accurate estimate of 90 hours on one charge. In Game Testing In COD, APEX and Fortnite my speed and accuracy were super smooth and accurate. I felt like my mouse glide with precision and the optical sensor switches were highly responsive. At times with same settings, I switched between a $200+ mouse and it performed worse at times unable to beat the Sony INZONE-A mouse. I had zero fatigue in all my game testing and was able to improve my K/D ever so slightly by being more accurate and quicker response on clicking. Overall: With Sony first entry with this gaming centric mouse, it’s a homerun. It hits every metric it claims and even exceeds it and then some on its DPI claims. If you’re a serious gamer who wants the best mouse and to have the competitive edge, I would make this mouse your main.
