Our Verdict
Logitech MX Keys
Keychron K4
For most uses, the Logitech MX Keys is better than the Keychron K4. Both are wireless keyboards, and both have a multi-device pairing feature for multitasking. Although both feel great to type on, they provide very different typing experiences since the Logitech is a low-profile keyboard with scissor switches, and the Keychron is a mechanical keyboard with a fairly high profile. The Logitech has software support, which the Keychron doesn't have, and it produces less typing noise, which is better for quiet offices.
