Keychron B6 Pro Ultra-Slim Wireless Keyboard
A full-size, ultra-thin wireless keyboard with scissor switches, ZMK programmability, and absurdly long battery life — the closest thing to a Magic Keyboard with a real typing feel.

What we like
- Only 5.2mm thick — looks and feels like a Magic Keyboard
- Triple connection: 2.4GHz, Bluetooth 5.2, and USB-C wired
- ZMK firmware means real key remapping, not bundled junkware
- Quoted 1,200-hour battery life is genuinely days-to-weeks of use
- Scissor switches are quiet enough for shared offices and calls
Could be better
- Not a true mechanical board despite the Keychron name
- No backlighting at this price
- Plastic body feels light, less premium than aluminum slim boards
Full Review
The Keychron B6 Pro is aimed straight at people shopping the Apple Magic Keyboard or Logitech K780 and quietly wishing for something better. It’s a full-size, scissor-switch board that’s only 5.2mm thick — but unlike its Apple and Logitech rivals, it ships with ZMK firmware, multi-device wireless, and a USB-C cable in the box for $59.99.
It’s not a mechanical keyboard. Keychron’s marketing leans hard on the “custom” angle, but the switches here are low-profile scissors, similar to a MacBook keyboard. That’s the right call for this category — but worth saying plainly upfront.
Build and Feel
The B6 Pro is shockingly thin. The integrated 5.2mm body sits flatter than a Magic Keyboard, with a 3.2-degree tilt that keeps your wrists neutral without a riser. The chassis is plastic, so it weighs almost nothing — a tradeoff against the aluminum top plate Apple uses, but also why this keyboard costs a third of the price.
Typing feel is firm and quiet. Travel is short, the bottom-out is consistent, and the stabilizers don’t rattle on the spacebar or enter key. If you’ve used a recent MacBook, you already know what to expect — it’s that, but full-size with a numpad.
Connectivity and Battery
Three connection modes is the headline feature. 2.4GHz with the included dongle gets you a 1000Hz polling rate for desktop work, Bluetooth 5.2 pairs with up to three devices for laptop and tablet switching, and USB-C handles wired duty for meetings or low-battery emergencies.
The 1,200-hour battery claim is conservative because there’s no backlighting eating power. In practice, that’s weeks of typical office use between charges. Both the Magic Keyboard and the K780 need recharging or fresh batteries far more often.
ZMK and Customization
This is where the B6 Pro pulls clear of the competition. ZMK is open-source firmware with proper layer support, macros, and per-key remapping through Keychron’s web launcher. Apple gives you nothing. Logitech gives you Logi Options+, which is fine but locked to their ecosystem and limited in what it can rebind. Power users get real flexibility here without dropping into a config file.
Who Should Buy This
Buy the B6 Pro if you want a clean, low-profile desk setup and you switch between a Mac, a work laptop, and maybe a tablet. It’s the right pick for renters, hot-deskers, and anyone whose desk has to look tidy on video calls. If you specifically want mechanical switches with full travel and audible feedback, look at the Keychron K Pro or Q series instead — this board is for people choosing slim and quiet on purpose.
