What will you mostly use it for?
The B36 is the clear choice for office use and content creation due to its silent operation and full-size layout with media keys. For travel, the B1 Pro's compact, lightweight design is superior. Gaming and programming are ties, as both offer core programmability and performance, leaving the choice to personal layout preference. Modding potential is similarly limited on both pre-built boards.
It's a tie
- Both feature a 1000 Hz polling rate over their 2.4 GHz connection for responsive input.
- Both support tri-mode connectivity (2.4 GHz, Bluetooth, wired).
- The B1 Pro's compact 75% layout frees up mouse space, while the B36's full layout offers dedicated macro keys.

“I really like this keyboard, particularly due to its ISO PT layout. For the next iteration, I suggest using a higher-quality plastic, as the keycaps feel a bit cheap. I would easily pay 20/30 EUR more if the keyboard felt more premium.”

“The battery life easily lasts weeks for me. Bluetooth and 2.4GHz both feel stable, and the adjustable angles help reduce wrist strain.”
