If you want

  • 96% layout includes a numpad and arrow keys in a compact form.
  • Features a silent scissor switch mechanism with pre-lubed keys for quiet typing.
  • Offers adjustable typing angles (6.5° and 9°) for better ergonomics.

Your primary need dictates the choice. If you require a full layout for number crunching, value silent typing, and want adjustable angles, the Keychron B35 is the more capable daily driver. If your priority is portability, a low-profile typing experience, or a specific ISO layout, the slimmer and lighter Keychron B1 Pro is the better fit. Both provide reliable tri-mode connectivity at a similar price.

Best for

What will you mostly use it for?

The B35 is the clear choice for office work and content creation due to its numpad, silent operation, and adjustable ergonomics. The B1 Pro wins for travel and programming, where its ultra-slim, lightweight design and ISO layout options are more valuable. For gaming and modding, the keyboards are evenly matched, sharing core wireless performance but similar limitations in rollover and hardware customizability.

For gaming

It's a tie

  • Both offer a 1000 Hz polling rate over 2.4 GHz for responsive input.
  • Both lack N-key rollover, which may be a limitation for complex key combinations.
  • The B1 Pro's low-profile design may appeal to some gamers, while the B35's silent typing is better for shared spaces.

FAQ

Keychron B1 Pro vs B35: your questions

The Keychron B35 is designed for quiet environments. Its vendor description specifically highlights silent typing with a scissor mechanism and pre-lubed keys to minimize noise, making it more suitable for shared office spaces than the standard low-profile switches of the B1 Pro.

Only the Keychron B35 has a number pad. It uses a 96% layout that integrates a numpad, arrow keys, and navigation cluster into a compact form. The B1 Pro is a 75% layout, which omits the numpad and some navigation keys to save space.

No, neither keyboard supports hot-swapping. The product specifications do not list hot-swappable sockets, and both are described as pre-built. Customization is limited to the Keychron Launcher software for key remapping and macros.

According to their vendor pages, the Keychron B1 Pro claims up to 1200 hours of battery life, while the B35 claims up to 320 hours. Both use an 800mAh battery, but the B1 Pro's ultra-slim, low-profile design likely contributes to its significantly higher claimed efficiency.

The Keychron B1 Pro is significantly more portable. It weighs 425g compared to the B35's 510g, and is only 5mm thick versus the B35's 17.94mm front height. Its 75% layout is also more compact than the B35's 96% layout.

Yes, both the Keychron B1 Pro and B35 support macOS and Windows. Their product listings mention Mac/Win support and a system toggle switch. The Keychron Launcher software also allows for configuring separate keymaps for each operating system.

The Keychron B35 has an adjustable typing angle. According to its specs, it offers angles of 5°, 6.5°, and 9°. This is more versatile than the B1 Pro, which has a fixed, low typing angle of 3°.

Yes, the Keychron B1 Pro is listed as a low-profile keyboard. Its specifications include 'Low Profile' as a feature, and its vendor description calls it an 'ultra-slim' and 'ultra-thin' keyboard with a 5.2mm integrated body thickness.

Both keyboards offer tri-mode connectivity: 2.4 GHz wireless with a 1000 Hz polling rate, Bluetooth 5.2, and a wired USB-C connection. This allows you to connect to multiple devices simultaneously and switch between them easily.

The Keychron B35 offers more ergonomic adjustability. It features user-adjustable angles (6.5° and 9°), while the B1 Pro has a fixed 3° angle. The B35's vendor description also mentions its taller keycaps and scissor mechanism are designed for stability and reduced fatigue.

The available information does not mention ISO or UK layout options for the Keychron B35; it is listed with an ANSI layout standard. For a UK layout, the Keychron B1 Pro is the better choice, as its vendor page explicitly lists a UK-ISO version among its many ISO layout options.

No, neither the Keychron B1 Pro nor the B35 have RGB backlighting. The specifications for both keyboards clearly list 'RGB: No'. They are non-backlit keyboards.
