Differences Between Sizes And Variants
The Corsair M75 AIR is available in Black, White, or Gray color options. Corsair also sells a limited "Launch Edition" bundle, which includes the mouse in a Thunderbolt Yellow colorway, a mousepad, glass mouse skates, and grip tape, but it's only available directly on their website. We bought and tested the Black color model, and you can see the label for our unit here.
Compared To Other Mice
The Corsair M75 AIR is a wireless gaming mouse that's Corsair's first entry into the lightweight competitive gaming mouse market. It has a much more subtle design language than many of Corsair's other gaming mice, which are often laden with RGB lighting and aggressive styling. It has a medium-large, symmetrical shape that's suitable for all grip types and medium to large hand sizes.
This mouse's MSRP puts it in a premium price bracket, but it's regularly been on sale in the months following its launch. It offers excellent overall performance that rivals other premium lightweight gaming mice. That said, it's a great choice if you want the flexibility of its symmetrical shape but have larger-sized hands or prefer a larger mouse.

The Corsair M75 AIR and the Logitech G PRO X SUPERLIGHT 2 are high-end wireless gaming mice. They both are very lightweight and weigh virtually the same. The two perform similarly, but the Logitech has slightly better sensor latency performance. The Corsair has a maximum polling rate of 1000Hz, while the Logitech has a maximum polling rate of 8000Hz natively. Lastly, the two mice are both symmetrically shaped, but the Corsair is larger, making it more suitable if you have larger hands.
The Corsair M75 AIR and the Corsair SABRE RGB PRO WIRELESS are wireless gaming mice from Corsair. They are both strong performers, with similarly low click latency and sensor latency, but the M75 AIR has better mouse feet and build quality and is significantly lighter than the SABRE. They are both large-sized mice but with different shapes. The M75 AIR is symmetrical, and the SABRE has a right-handed shape. Lastly, the SABRE has RGB lighting, while the M75 AIR doesn't.
The Corsair M75 AIR and the Logitech G PRO X SUPERLIGHT are high-end, lightweight wireless gaming mice. They both have great gaming performance, but the Logitech has slightly better sensor latency performance and mouse feet that glide more easily than the Corsair. The Logitech also has slightly better build quality than the Corsair. On the other hand, the Corsair is larger than the Logitech, making it a better fit if you have bigger hands.
The Corsair M75 AIR and the Razer Viper V2 Pro are high-end, lightweight, wireless gaming mice with symmetrical shapes. The Corsair is notably larger than the Razer, so it's a better choice if you have bigger hands. The two mice perform similarly overall, but the Razer has slightly better sensor latency performance and mouse feet that glide more easily. The Corsair has a maximum native polling rate of 1000Hz, and the Razer supports a polling rate of up to 8000Hz, but you have to buy a HyperPolling dongle separately to reach that polling rate.
Test Results
The Corsair M75 AIR Wireless has a matte black plastic build with glossy black accents on the body and side buttons. It has a bright yellow scroll wheel, a glossy black Corsair logo on the palm rest area, and "// M75 AIR" written in gray on the left side of the mouse. There's no RGB lighting, but it has a small status LED beneath the L/R clicks.
This large-sized mouse isn't designed specifically for portability, but it has a compartment on its underside where you can store the USB receiver.
The Corsair M75 has very good build quality overall. The body is made from a slightly textured plastic that feels grippy. There's no noticeable flex in the body, but you can activate the back side button if you apply substantial pressure to the side of the mouse underneath it. There's also a rattling sound when you shake the mouse, but these issues aren't noticeable during normal use.
This mouse is very lightweight, making it easy to move accurately and quickly.
The Corsair M75 AIR has a symmetrical shape that's best suited for medium and large-sized hands. It has a centered hump and a shape that slightly tapers from the back to the front. The result is a versatile shape that's suitable for all grip types, but those with smaller hands might have trouble reaching the side buttons.
You can connect to this mouse wirelessly using its 2.4 GHz USB receiver or Bluetooth. Corsair advertises that it has up to 34 hours of battery life with the USB receiver or up to 100 hours via Bluetooth. You can also connect to two devices simultaneously and switch between them using the button on the bottom of the mouse.
The Corsair M75 AIR includes a braided USB-C charging cable. It has mediocre flexibility and retains some permanent kinks from its packaging.
This mouse's feet glide smoothly across desks and mousepads but have a slightly scratchy sound; this doesn't affect gliding performance. Third-party replacement feet are also available, and Corsair sells compatible glass mouse feet on their website.

You can reprogram the right-click, scroll click, and the two side buttons on this mouse. There's a power/connection button on the underside of the mouse.
This mouse has superb click latency performance that delivers a very responsive experience suitable for gaming in any genre. We performed this test at its maximum polling rate and with Button Response Optimization disabled.
Button Response Optimization is a software setting that adds debounce delay to prevent slam clicks. We ran an additional test to see how much click latency it adds and found that it increased it to 17.5ms. Here is the graph of our results.
This mouse has remarkable CPI performance overall. The physical movements you make with it translate extremely closely to your cursor movements on the screen.
This mouse has excellent sensor latency performance overall. It reacts quickly to your movements, and you won't notice any delay, making it suitable for casual and competitive play. We tested this mouse at its maximum polling rate.
The Corsair M75's available polling rate settings are 125Hz, 250Hz, 500Hz, and 1000Hz. An LED below the left-and right-click buttons indicates your current CPI setting. Unfortunately, there isn't a dedicated button that cycles through CPI settings, so you must manually change your CPI mode using the companion software.
Note: When we originally tested this mouse, its maximum advertised polling rate was 2000Hz. Corsair has since removed this rate from the software and some of the marketing material.
We've retested the Click Latency and the Sensor Latency and found no significant difference in performance. This is because its 2000Hz implementation operated at an effective polling rate of 1000Hz. It worked by sending two reports to your computer at 1-millisecond intervals, while most other mice with a 2000Hz polling rate send one report every 0.5 milliseconds.

The Corsair M75 AIR has a rubberized scroll wheel with fine grooves for added grip. Scrolling is precise, with smooth but noticeable step increments. There's an audible noise when you scroll quickly, but it still operates quietly overall.
The left- and right-click buttons, side buttons, and the scroll wheel operate quietly and are unlikely to bother anyone around you.
Corsair's iCUE software lets you customize various settings like CPI, polling rate, lift-off distance surface calibration, button optimization, and more. It's reasonably straightforward to use. However, some settings, like macro programming and button assignment, are less intuitive. That said, most users won't have much difficulty with it.
Additionally, much like similar software options from other major manufacturers, this software is the source of criticism from the broader community. While we didn't experience any issues during the testing of this mouse, many users online criticize this software for requiring frequent updates and taking up disproportionate system resources, among other complaints. This software may be frustrating if you prefer more lightweight software options or no software at all.
