Description

A slim keyboard with a quiet sound

The Banana switch is tactile: you feel a light bump at the start of the press that tells you the keystroke has registered. The POM switches come pre-lubed and give a deeper sound than most low-profile designs. Inside, IXPE, EPDM and latex foam layers soften the key noise. The tilt has three positions: 2.5°, 4.2° or 6.5°. LSA-profile ABS keycaps let the RGB backlight shine through the legends, with more than 22 effects.

Who this keyboard is for

People who type a lot at home or in the office and switch between a computer, tablet and phone; Mac users, as the Mac layout and keycaps are included along with a separate Windows set; and travellers who want a low keyboard that fits in a bag. Every key can be remapped in the Keychron Launcher web app without installing any software.

Questions & answers

Does the keyboard have Estonian letters?

No. The layout is English QWERTY (ANSI) and Õ, Ä, Ö, Ü are not printed on the keys. Add the Estonian keyboard layout in your operating system to type them.

Does it have a 2.4 GHz receiver?

No. This version connects wirelessly only over Bluetooth 5.2 (up to three devices), plus a USB-C cable. For gaming the cable is faster: 1000 Hz versus 90 Hz wireless.

How long does the battery last?

The battery is 1550 mAh and the manufacturer rates it at up to 124 hours. Real runtime depends on how much you use the backlight.
