Raw Performance

The Corsair M75 AIR is Corsair's flagship wireless FPS gaming mouse that marks their first entry into the lightweight mouse market. It's a large-sized mouse with a symmetrical shape and features Corsair's MARKSMAN sensor that supports a 2000Hz maximum polling rate. You can connect this mouse wirelessly using the included 2.4 GHz USB receiver or via Bluetooth, and it also supports multi-device pairing.

Our Verdict

7.2 Work

Although not specifically designed for it, the Corsair M75 AIR is decent for work use. Overall, it has very good build quality and a comfortable, symmetrical shape suitable for any grip type. You can connect to it using its USB receiver or Bluetooth, and it also supports pairing to two devices simultaneously. It lacks some productivity features like L/R tilt inputs and free-scrolling.

Pros
  • Symmetrical shape is comfortable for most hand sizes and grip types.
  • Supports Bluetooth and multi-device pairing.
Cons
  • Scroll wheel lacks L/R tilt inputs and free-scrolling.
9.1 Video Games (FPS)

The Corsair M75 AIR is a remarkable FPS gaming mouse. It's very lightweight, making it easy to aim quickly and precisely. It also has extremely low and consistent click latency performance and excellent sensor performance overall. While this mouse has a maximum polling rate of 2000Hz, its implementation falls short of others we've tested with a 2000Hz polling rate. For more details, see the Sensor Latency section.

Pros
  • Symmetrical shape is comfortable for most hand sizes and grip types.
  • Very lightweight.
  • Excellent overall sensor performance.
  • Remarkably low click latency.
Cons
  • Unusual 2000Hz polling rate implementation that falls short of other mice tested at 2000Hz.
7.8 Video Games (MMO)

The Corsair M75 AIR isn't designed specifically for MMO gaming but is still a good mouse for this usage. It doesn't have nearly as many additional buttons as a dedicated MMO mouse, but you can still reprogram some of its buttons using Corsair's companion software. Otherwise, it has excellent click latency and overall sensor performance, and its symmetrical shape and light weight make it comfortable to use for long periods.

Pros
  • Symmetrical shape is comfortable for most hand sizes and grip types.
  • Excellent overall sensor performance.
  • Remarkably low click latency.
Cons
  • Unusual 2000Hz polling rate implementation that falls short of other mice tested at 2000Hz.
  • Significantly fewer side buttons compared to dedicated MMO gaming mice.
9.4 Raw Performance

The Corsair M75 AIR has remarkable raw performance overall. It has superbly low click and sensor latency and reacts accurately and quickly to your movements and inputs. However, it has marginally higher sensor latency than expected, and its polling rate performance is slightly less consistent than that of other mice we've tested with a maximum polling rate of 2000Hz. For more details, see the Sensor Latency section.

Pros
  • Excellent overall sensor performance.
  • Remarkably low click latency.
Cons
  • Unusual 2000Hz polling rate implementation that falls short of other mice tested at 2000Hz.

Differences Between Sizes And Variants

The Corsair M75 AIR is available in black. 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. You can see the label for the unit we bought and tested 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. It also has Corsair's MARKSMAN sensor, which supports a polling rate of 2000Hz.

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 but falls short in its implementation of a 2000Hz polling rate, which is worse than rivals like the Logitech G PRO X SUPERLIGHT 2. 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.

For more recommendations, see our picks for the best FPS mouse, the best gaming mouse, and the best lightweight mouse.

Logitech G PRO X SUPERLIGHT 2

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. Like the Logitech, the Corsair has a maximum polling rate of 2000Hz, but its implementation isn't as effective and doesn't perform quite as well. Lastly, the two mice are both symmetrically shaped, but the Corsair is larger, making it more suitable if you have larger hands.

Logitech G PRO X SUPERLIGHT

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 mouse supports a higher maximum polling rate of 2000Hz, but its implementation isn't great and doesn't give it an advantage over the Logitech model. Lastly, the Corsair is larger than the Logitech, making it a better fit if you have bigger hands.

Razer Viper V2 Pro

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 2000Hz, 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.

Corsair SABRE RGB PRO WIRELESS

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. The M75 AIR also has a higher maximum polling rate of 2000Hz. 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.

This mouse has superb click latency performance that delivers a very responsive experience suitable for gaming in any genre. We performed this test at a polling rate of 2000Hz 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 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 a polling rate of 2000Hz.

The delay to end of movement is slightly higher than we expected. We re-ran our tests multiple times to verify and are confident in our results. The performance is still fantastic but can have a marginal impact at the highest competitive levels.

Note: Like other recent Corsair mice we've tested, this mouse operates differently at its 2000Hz polling rate setting than other mice with polling rates of 2000Hz or higher. At its 2000Hz setting, this mouse sends two reports to your computer at 1-millisecond intervals, while most other mice we've tested with a 2000Hz polling rate send one report every 0.5 milliseconds. While the sensor latency performance is still excellent overall, it's measurably less consistent than most 2000Hz options from other manufacturers.

The Corsair M75's available polling rate settings are 125Hz, 250Hz, 500Hz, 1000Hz, and 2000Hz. 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.

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.
