SpecPicks Verdict

SpecPicks scored Das Keyboard 4 Professional Wired Mechanical Keyboard using a rating × review-volume × price-fit model applied to published specs and reviews across the gaming peripherals category. Das Keyboard's gaming peripherals lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Frequently Asked Questions

Does the Das Keyboard 4 Professional support N-key rollover over USB?

Yes. It supports full N-key rollover over USB. Press Shift + Mute to toggle NKRO on. The manufacturer says this works on both Windows and Linux, so you don't need a PS/2 adapter.

Do the USB 3.0 hub ports need a second cable to the PC?

No. The keyboard and its 2-port USB 3.0 hub share one 6.5 ft (201 cm) cable with a single USB-A connector. The hub is rated for transfers up to 5Gb/s, and the ports can charge devices.

How loud are the Cherry MX Blue switches?

MX Blue switches make an audible click along with the tactile bump at the actuation point. Most typists like that feedback, but if you work in a quiet shared room or take a lot of calls, the click may be noticeable to people near you.

How long will the switches and keycaps last?

Das Keyboard rates the gold-plated Cherry MX Blue switches for up to 50 million keystrokes. The keycaps are laser-etched, so the legends hold up to heavy use. Check the product listing for current warranty terms.

Can I adjust the keyboard's typing angle?

Yes, with the included magnetically detachable footbar, which doubles as a ruler. Attached, it raises the keyboard to a 4-degree angle. Remove it if you want the board flat.
