If you play with a Sony DualSense controller or , you're probably very familiar with haptic feedback by now. It is practically unheard of for mouse and keyboard players, though, yet recent leaks suggest Logitech could be employing the rumbly tech.
According to , the new Logitech MX Master 4 has haptic feedback "to provide feedback [[link]] on actions such as changing computers, adjusting the cursor, and similar actions". It seems that, instead of being used to heighten immersion in games, it has a much plainer, but likely more productive, use.
This is not Logitech's first time putting any sort of feedback in a mouse, but it is Logitech's first one in some time. The iFeel was an optical wired mouse from 2000 that employed feedback. With a whopping DPI of 800, this little rodent looks very .
Winfuture also claims that the new MX Master 4 has a "new, more durable, slightly textured surface", which should make it easier to clean, too. The report claims Logitech will be implementing a new "Actions Ring" function, which is an overlay near the thumb rest that can be customized to perform certain actions from within Logitech's software. It will also reportedly get quieter clicks and a Darkfield sensor that goes up to 8000 DPI.
Finally, Winfuture claims that the Logitech MX Master 4 will have up to 70 days of battery life and will launch on September 30, 2025 for €130. US pricing is not given, but that equates to around $151. The is currently on sale for $100, with the coming in at $120.
That does appear to be a hefty price increase, so we'll have to hope it's a big enough improvement over the last mouse to justify the cost.
