Keychron M4 4K Wireless Mouse Review: Compact Design Meets Daily Use

I’ve spent a fair bit of time contemplating how to approach this review of the Keychron M4 4K Wireless Mouse. On one hand, its size and weight are intriguing, offering a distinct take in the vast sea of gaming peripherals. On the other, it doesn’t significantly break new ground compared to Keychron’s other lightweight offerings like the M3 Mini or the M2 Mini. It’s more about the design preference—do you find its shape appealing?

Introduction to the Keychron M4 4K Wireless Mouse

Personally, while I haven’t dwelled much on the M2 models previously, their design never quite appealed to me, not due to their functionality but purely based on aesthetics. The M4, with its unique size, stands out, but it’s a double-edged sword. Its compactness, though a potential boon for portability, led to hand cramps within just a week of use—a testament to the fact that sometimes, smaller isn’t always better.


Despite these shortcomings, the mouse’s lightness is undeniably appealing, particularly when you’re not using it for intensive tasks. It’s when the workload ramps up, requiring precision and endurance, that the M4’s limitations become apparent. It’s perfect for those looking for a minimalist, portable mouse, but for long-term use in work-intensive scenarios, it might not be the best fit.

The Design and Usability of the Keychron M4

Exploring further, the M4’s appeal doesn’t wane when it comes to its design and the ‘cool factor’ of its lightness. Yet, its practicality for extended use, especially in tasks demanding precise control and comfort, begins to wane. The novelty of its size and weight, while initially fascinating, doesn’t necessarily translate to a seamless user experience for activities beyond casual browsing or light gaming.

The aesthetics of the M4, coupled with its portability, make it a compelling choice for those on the move. Its low-profile design ensures it blends in rather seamlessly with your workspace, especially if you’re someone who appreciates a minimalist setup. However, the small form factor, as I’ve found, might not suit everyone—myself included.


When it comes to its performance and specifications, the M4 doesn’t stray far from what you’d expect from a modern wireless mouse within Keychron’s lineup. The distinctions between this and other models like the M3 Mini 4K, particularly in terms of functionality, are marginal at best. It’s here that the design and size preferences really come into play, shaping your decision more than any technical specification might.

Final Thoughts and Recommendation

In closing, while the Keychron M4 4K Wireless Mouse boasts an impressively light frame and an aesthetic design, it falls short for those seeking ergonomic comfort for prolonged use. Its size, while perfect for portability, might not cater to everyone’s needs, especially for those with larger hands or those who use their mouse for intensive tasks over long periods.

Would I recommend the Keychron M4? It depends on what you’re looking for. If you value a mouse that’s light and portable, easy to carry around without feeling its weight, the M4 is an excellent choice. But if you’re like me, prioritising comfort and ergonomics for long hours of use, you might find the M4 lacking. It’s a great mouse within its design intentions but consider your usage patterns and preferences before making the leap.


At the end of the day, the Keychron M4 4K Wireless Mouse is a testament to Keychron’s commitment to offering diverse options catering to different user preferences. It’s not about one size fitting all but about providing choices that meet varied needs. For me, the search for the perfect mouse continues, but the M4 will undoubtedly appeal to those looking for portability and sleek design in their peripherals.
