The Keychron B1 Pro is a compact, wireless-compatible membrane keyboard that bears a strong resemblance to the Logitech MX Keys Mini. With its low-profile, slim design, the B1 Pro is a good choice for hybrid office workers who need a portable, versatile keyboard.
At a price of $39.99 USD, the B1 Pro stands out by undercutting both the Logitech MX Keys Mini and Apple Magic Keyboard, providing a more affordable option for users seeking a compact and stylish keyboard. It also supports ZMK customization via Keychron Launcher, giving users the ability to remap keys, program macros, and set up shortcuts - a feature not available in its direct competitors.
Available in Space Gray and Ivory White, the B1 Pro offers flexibility in connectivity, with options for wired, 2.4 GHz wireless receiver, or Bluetooth modes. While some users may prefer the more reactive keys and solid construction found higher-priced models, the B1 Pro remains a practical choice for everyday typing needs.
WHAT YOU NEED TO KNOW
THE GOOD
- Price
At $39.99 USD, the Keychron B1 Pro is much more affordable than competitors like the Logitech MX Keys Mini and Apple Magic Keyboard, offering a budget-friendly option for users seeking a compact, versatile keyboard.
- Customization
Unlike its competitors, the B1 Pro is compatible with ZMK customization via Keychron Launcher.
- Portability
The low-profile, lightweight design makes it easy to carry, ideal for hybrid office workers who need a keyboard on the go.
THE BAD
- Build Quality
The all-plastic chassis can lead to a noticeable board flex during typing, which may not appeal to users accustomed to more rigid constructions.
THE REST
- Overall
The Keychron B1 Pro is a budget-friendly alternative to popular compact keyboards, offering customization options and a sleek, portable design. However, its build quality might not satisfy all users, especially those looking for more premium features.
The Keychron B1 Pro package includes the keyboard, a USB Type-C cable, a USB Type-A to Type-C adapter, a USB Type-A 2.4 GHz receiver, and a silicone skin protector for the keyboard. It has a compact 75% layout with a full function row and shared media control keys.
The keyboard's all-plastic chassis contributes to its lightweight design, but it also introduces some board flex during use. The ABS plastic keycaps have a slight concave shape, providing a smoother typing experience, although they lack the pronounced contour of the Logitech MX Keys Mini. The B1 Pro can connect via wired, wireless, or Bluetooth. These connectivity options can be selected with a switch on the keyboard, as well as a switch for swapping between Windows and macOS systems.

The B1 Pro's customization capabilities are powered by the Keychron Launcher, which utilizes ZMK software. This allows users to remap keys, set macros, and configure shortcuts, enhancing productivity across various tasks. The keyboard is compatible with multiple operating systems, including macOS, Windows, and Linux.
One of the trade-offs of the B1 Pro's design is the lack of backlighting, which may be a limitation for users who prefer typing in low-light environments. However, this feature helps extend the device's battery life making it more efficient for travel and daily use.
The Keychron B1 Pro utilizes membrane switches with a typing feel, employing scissor switches that provide a smooth and quiet typing experience. While these switches may feel scratchy to users accustomed to mechanical keyboards, they are sufficient for everyday typing tasks.
In Bluetooth mode, the keyboard has a relatively high latency of 30.7 ms, while in wired and wireless receiver modes, it achieves latencies of 22.7 ms and 24.6 ms, respectively. Though not built for high-speed gaming, the B1 Pro performs adequately for casual, daily use.
The B1 Pro does not include a wrist rest, but its low-profile design and fixed 3° incline angle help to make extended typing sessions more comfortable. The B1 Pro's compact and portable design makes it a convenient choice for users who need a keyboard that can easily travel between different work environments.
