Corsair M75 Wireless Review: A Blend of Style, Flexibility, and Performance

Following the successful launch of the M75 Air, Corsair has unveiled its newest iteration, the M75 Wireless. This model is not a complete overhaul but rather a refined version, incorporating RGB lighting and a true ambidextrous design. These new features come with additional weight, giving the mouse a more balanced feel compared to its lightweight predecessor. I had the opportunity to use the Corsair M75 Wireless for three weeks to see how it measures up against other top gaming mice currently available.

Design

If you’ve seen the M75 Air, the design of the M75 Wireless will be familiar. The signature humped form factor remains, though the new model weighs in at 89 grams, up from the Air's 60 grams. This added weight provides a more centered and substantial feel, albeit perhaps at the expense of being the ideal choice for fast-paced FPS games.

The most noticeable change in design is the inclusion of two RGB strips along the back, illuminating the sides around an equally luminous Corsair logo. This tasteful touch adds a sleek edge to the white model, making it stand out more prominently on your desk. Configurable in two zones via iCue software, the RGB lighting offers an immediate visual upgrade from the original Air, fitting seamlessly into any RGB-illuminated setup.

The mouse’s shape is versatile, lending itself well to both palm and claw grips. The humped middle, steep gradient along the main clicks, and softer slope at the back provide excellent control. However, the additional weight and length make it less suitable for fingertip grips.

You’ll also find two buttons underneath: one for managing DPI settings and the other for connections. Moreover, the PTFE feet are divided into three sections to guarantee a seamless glide on different surfaces. The functionality of each button is indicated lightly on the side, which can be difficult to see initially. There’s even a handy storage spot for the USB-A dongle underneath the mouse.

Overall, the design is commendable. The white model I tested looks pristine against a black mouse pad, though I would have preferred a white scroll wheel for a more cohesive aesthetic.

Features

The standout feature of the Corsair M75 Wireless is its ambidextrous design. It comes with side buttons on both flanks and additional caps that can be swapped out for a true left or right-handed experience. While the extra pieces offer flexibility, identifying the right component for each side can sometimes feel overly complex due to their similar thickness. Each side can be fitted with slightly raised buttons for the main side and nearly flush buttons for the opposite side. By default, both sides are active but can be customized or deactivated via iCue software.

In terms of programmable buttons, the M75 Wireless falls short. More buttons or functionality would have justified the price better. Adding features like a sniper button, tilt-clicks on the scroll wheel, or a dedicated DPI shifter would have enhanced its appeal, especially since it moves away from an ultralight design.

Despite the limited programmable options, the core features are impressive. The Marksman sensor offers 26K DPI at 650 IPS, providing ultra-precise tracking. While some competitors, like the Razer Viper V2 Pro, push DPI up to 30K, the M75 Wireless still outperforms many other models like the Logitech G Pro Wireless in this aspect.

Another noteworthy feature is the on-the-fly DPI adjustment. Although it lacks a dedicated DPI shifter, holding the DPI button at the mouse's base while clicking the side buttons allows for fine-tuned sensitivity adjustments directly on the device. This is particularly handy for customizing settings across different games without needing to dive into any software.

The M75 Wireless also excels in battery life. Corsair estimates about 105 hours when connected via 2.4GHz, and I managed around 70 hours with RGB on, which is a considerable improvement over the original M75 Air's 34 hours.

Performance

The M75 Wireless truly shines in adventure games. While its added weight and larger size may be a disadvantage for fast-paced games like Apex Legends and CS:GO, the sensor and tracking capabilities remain top-notch. During complex MOBA sessions, I occasionally found myself glancing at the Darkstar Wireless due to its specialized features. Nevertheless, the M75 Wireless provides precise and responsive tracking, excelling in everything from frantic battles to precise sniping.

The mouse’s heavier build doesn’t significantly hinder its performance. It glides well across surfaces, offering a balance between speed and comfort. Corsair has equipped the main buttons with Quickstrike switches, which feel responsive and offer a satisfying click. They handle repeated clicks effortlessly, maintaining a good balance of precision and comfort.

Should You Buy the Corsair M75 Wireless?

The M75 Wireless may not be ideal for solo FPS players due to its weight or for MMO gamers due to its limited number of buttons. However, it is an excellent all-rounder, offering a comfortable form factor, thoughtful extra features, and a high-quality sensor. If you're using the older M75 Air, the M75 Wireless might not offer enough new features to warrant an upgrade. Still, for those seeking a stylish and versatile right or left-handed gaming mouse, it’s worth considering.

Comparatively, it stands out against the Logitech G Pro Wireless, particularly regarding its sensor, switches, and battery life. If you're looking for top speed and don't mind spending a bit more, the Razer Viper Ultimate could be the ideal option. It also features dual side buttons and often comes with a wireless charging cradle.

If wireless functionality isn't essential, a wired version of the M75 is available for a lower price.

Testing Insights

I utilized the Corsair M75 Wireless for three weeks, integrating it into my daily activities for work and gaming. My tests included Apex Legends, Assassin’s Creed Odyssey, and House Flipper, along with stress tests in CS:GO, Halo Infinite, and Elder Scrolls Online.
