Our Verdict

Microsoft Surface Keyboard

Keychron K4

The Microsoft Surface Keyboard and the Keychron K4 are very different keyboards. Both are Bluetooth keyboards, but only the K4 has a multi-device pairing feature. The Microsoft uses scissor switches and chiclet-style keys, while the Keychron is a mechanical keyboard that you can customize with the switches of your choice. The LK Optical Brown switches on our K4 provide a better typing experience, but the Microsoft's low profile makes it a bit more comfortable to type on without a wrist rest. The Keychron has backlighting, which the Microsoft doesn't have, and it has a built-in rechargeable battery instead of using disposable batteries.
