Corsair M75 Air Wireless review: Lightweight contender

Corsair M75 Air

The Corsair M75 Air Wireless is the latest entry in the crowded lightweight, untethered gaming mouse category. Weighing in at 60g, it competes with the likes of the Logitech G Pro X Superlight 2 and Razer Viper V2 Pro.

Quick specs:

  • 60g
  • 100hr battery (Bluetooth) / 34hr battery (2.4GHz)
  • Optical sensor: 26,000 DPI / 650 IPS tracking / 50g acceleration
  • USB-C charging / USB-A Slipstream Wireless dongle

There's nothing fancy about the M75's design. It comes in black with dashes of yellow, and would look right at home even in an office setting. Though symmetrical, the M75 is primarily meant for right-handers due to the position of the side thumb buttons. There are no fancy lights, just a single LED on the top surface that lets you know which mode the mouse is in. On the bottom of the mouse is a button to toggle between 2.4GHz, and Bluetooth modes. There's a receptacle to store the wireless dongle, too. Finally, a USB-C port for charging is at the front.

I like how the M75 feels in the hand thanks to its matte surface. Its raised hump isn't overly pronounced, and fits my small hands nicely when using a palm grip. I found the buttons responsive during my time playing FPS games, which Corsair attributes to its use of optical switches. These are also supposed to be more reliable, which could be a factor for users who have had issues with mechanical switches. Button presses come with an audible click. This is a bit louder than my Razer Viper but it isn't loud enough to be annoying.

The M75's polling rate goes up to 2,000Hz, DPI up to 26,000, and up to 50g acceleration. I personally use a lower DPI, which I had to adjust using the iCue software. Those who want to cycle between different DPIs during games won't be able to do so, as the iCue software doesn't have such an option. You can, however, assign a key to toggle Sniper mode, which switches to a lower, preset DPI, and upon letting go of the key, returns to your previous DPI setting. The M75 gets up to 100 hours of battery life on Bluetooth. However, most users will probably be using the 2.4GHz mode with its dongle, which has up to 34 hours battery life. During my week-long test, I got about 30 hours of use before having to charge.

With so many similar features, and good performance, the S$199 Corsair M75 is a worthy alternative to the Logitech G Pro X Superlight 2. We do find the Logitech to be slightly more refined with better battery life, but it is also more costly at S$249. The Corsair M75 Air Wireless retails at S$199 from Shopee and Lazada.
