Best for

What will you mostly use it for?

The B6 Pro is the clear choice for office work and content creation where a number pad is non-negotiable, and it adds RGB lighting. The B1 Pro wins for travel and programming due to its compact, lightweight design that saves space. For gaming and modding, the decision is more nuanced, tied to layout preference versus lighting and specific mounting details.

For gaming

It's a tie

  • Both have a 1000 Hz polling rate over their 2.4 GHz connection for responsive input.
  • Both support the same switch types (linear, tactile, clicky) for personal preference.
  • The B6 Pro's north-face RGB lighting may offer better visibility in dim environments.
  • The B1 Pro's lighter weight and smaller footprint can free up more desk space for mouse movement.

“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.”

FAQ

Keychron B1 Pro vs B6 Pro: your questions

The main difference is the layout size. The B1 Pro is a 75% keyboard, which omits the number pad and some navigation keys to save space. The B6 Pro is a full-size 100% keyboard that includes a dedicated number pad. The B6 Pro also adds north-face RGB backlighting, which the B1 Pro lacks.

The Keychron B1 Pro is better for travel. It is significantly more compact at 296mm wide and lighter at 425g compared to the B6 Pro's 429mm width and 623g weight. The smaller 75% form factor is easier to pack and fits on tighter surfaces like airplane trays or small cafe tables.

Yes, the Keychron B6 Pro features north-face RGB backlighting. The Keychron B1 Pro does not have any backlighting, which is a key differentiator between the two models for use in low-light conditions.

Yes, both keyboards support ZMK (Zephyr-based Mechanical Keyboard) firmware customization. This is done through the Keychron Launcher web app, which allows for key remapping, macro creation, and setting up shortcuts according to the vendor descriptions.

Both the B1 Pro and B6 Pro support triple connectivity: 2.4 GHz wireless using a dongle, Bluetooth, and a wired USB-C connection. The vendor pages state they support Bluetooth 5.2 and a 1000 Hz polling rate over the 2.4 GHz connection.

The B6 Pro has a larger 1200mAh battery, while the B1 Pro has an 800mAh battery. However, the vendor descriptions for both claim up to 1200 hours of battery life. The actual runtime may vary based on usage, with the B6 Pro's RGB lighting likely consuming more power if used.

Yes, both keyboards are listed with Mac/Win support. The vendor descriptions note they offer a Mac layout with specific multimedia keys but remain compatible with Windows. The Keychron Launcher also allows you to configure keymaps for both operating systems.

The vendor description for the Keychron B1 Pro specifically mentions it includes a protective, washable silicone skin that fits over the keys. The description for the B6 Pro does not mention this accessory, so it may not be included.

The Keychron B6 Pro has a fixed typing angle of 3 degrees, as per the specifications. The vendor description further clarifies this as 3.2 degrees. The B1 Pro also has a 3-degree angle, but neither model has adjustable feet for changing the tilt.

The Keychron B6 Pro is more suitable for accounting or data entry due to its full-size layout with a dedicated number pad. The B1 Pro's 75% layout lacks a number pad, which would require using a layered function key or a separate numpad, slowing down data-intensive work.

Both keyboards use ABS keycaps and are low-profile designs. While the vendor descriptions do not specify if the keycaps are standard and swappable, the presence of a silicone skin for the B1 Pro suggests the keycaps are not sculpted in an unusual way. For confirmed compatibility, checking for low-profile keycap sets is recommended.

Based on the listed price ranges from vendors, both keyboards are in a similar, budget-friendly price tier. The B6 Pro, with its larger size and RGB lighting, may command a slightly higher price at the upper end of its range, but overall they are comparably priced.
