Our Verdict

Logitech MX Keys

Das Keyboard 4 Professional

The Logitech MX Keys and the Das Keyboard 4 Professional are very different keyboards. The Logitech is a wireless keyboard, which means it can be used with mobile devices, and you won't have a cable running from the TV to the couch in a home theater PC setup. It has backlighting, multi-device pairing, and it provides a better and quieter typing experience. The Das Keyboard has dedicated media keys and USB passthroughs, which the Logitech lacks. Neither keyboards are recommended for fast-paced gaming as they both have relatively high latency.
