What will you mostly use it for?
The B11 Pro is the clear travel-oriented option because it folds and is substantially lighter. The K10 Ultra leads in gaming, programming, and modding based on its higher polling rate, hot-swap support, and customization features. Its full-size layout and multimedia keys also make it the more feature-rich choice for office and content-creation desks. Choose the B11 Pro instead when compact portability and an Alice layout matter more than a full-size set of keys.
Pick the Keychron K10 Ultra
- K10 Ultra lists 8000 Hz polling over wired and 2.4 GHz, compared with the B11 Pro's 1000 Hz.
- K10 Ultra supports N-key rollover in wired and wireless modes.
- The B11 Pro has a 1000 Hz polling rate in wired and 2.4 GHz modes.
