Using Logitech’s MX Master mouse can really feel such as you’re slipping your hand right into a cradle form-fitted to your palm. Even if the MX Master lineup has been constantly good, the MX Master 3 proved such a staple that some customers proceed to flit round on their 8-year-old mouse even because it disintegrates between their getting old fingers. Logitech could lastly have the replace we’ve been ready for with an MX Master 4. Logitech doesn’t have to vary a lot for it to be one among the greatest productiveness mice as soon as once more, although it’ll have to think about one thing novel to entice present customers to improve.
The recurrently dependable leaker Evan Blass shared on X an image of what he steered was the Logitech MX Master 4. It already appears to be like very, similar to the MX Master 3 from 2017 and the MX Master 3S redux from 2022. He even steered that the calming mint inexperienced define round the thumb groove is “illustrative” and received’t be on the ultimate design. That’s a disgrace, as the further accent might have been one among the few options that actually set the design aside from earlier years.

The upcoming mouse launch is an open secret. Logitech already spoiled the shock in latest back-to-school promos. Back in May, the Brazilian-language web site Tecnoblog (by way of 9to5Mac) first reported on the Bluetooth certification paperwork for the MX Master 4. Reddit customers have additionally shared photographs of early teasers that Logitech posted to Instagram, confirming the leaked design. The wi-fi mouse nonetheless appears to make use of the seven-button design with the metallic prime and facet scroll wheels.
Fans of the MX Master 3 who haven’t already destroyed their mice in the eight intervening years could also be scratching their heads as to why they need to improve. There are very delicate modifications solely common customers would discover, like transferring the side-to-side scroll wheel up on the mouse, perched like a crow’s beak between the barely bigger click on buttons. The thumb relaxation now appears to have a brand new texture, although we’re eager to know if it’s sporting any new materials that might show extra sturdy for longtime use. So lengthy because it maintains the metallic scroll wheel and quiet clickiness that made the authentic so standard, then it is going to nonetheless be one among the greatest mice for working at a row of computer systems in right now’s white-collar digital meeting line.
The MX Master 3S’s predominant improve from the 2017 mouse was the transfer from a max of 4,000 to eight,000 DPI, or dots per inch. This measures the sensitivity of a mouse, which determines how exact it’s in hand. The MX collection is a productivity-first design, although that doesn’t cease some foolish customers from taking it into their favourite video games. What it’s missing is a polling price that goes past 125Hz. Polling price is how typically the mouse refreshes and transmits its place to the PC. The snappiest, high-end gaming mice, like the latest $170 Razer Deathadder V4 Pro, can hit a max 8,000Hz polling price. That’s such a excessive refresh price, even the most hardcore gamer wouldn’t be capable of inform the distinction. Other high-end productiveness mice like Razer’s $120 Pro Click V2 have a polling price as much as 1,000Hz, and if Logitech can match that quantity, the MX Master 4 might give customers a couple of extra choices for the place and the way they’ll use their mouse.
The leaks have had much less to share about the anticipated launch date or value, however we don’t anticipate the MX Master 4 will likely be any cheaper than the present $100 MX Master 3S, not with Trump tariffs nonetheless inflicting provide chain chaos throughout the PC panorama. I can solely anticipate that the one, excellent mouse for any and all of your wants will value much more going ahead.
