What will you mostly use it for?
The B31 wins for general-purpose use as a primary keyboard in office, programming, and travel scenarios due to its complete layout and portability. The Q0 HE dominates for specialized gaming and modding, offering unparalleled switch customization and gaming features. For content creation, the Q0 HE is a powerful accessory, but it requires a separate main keyboard to be functional.
Pick the Keychron Q0 HE
- The Q0 HE features Hall Effect magnetic switches with adjustable actuation points from 0.2 to 3.8 mm and Rapid Trigger support.
- It includes gaming-centric features like Last Key Priority (LKP), Snap Click, and Analog Mode for controller-like input.
- Its 1000 Hz polling rate in 2.4 GHz and wired modes matches the B31, but the switch technology is specifically designed for gaming precision.

Keychron B31 vs Q0 HE: your questions
No, the Q0 HE is exclusively a number pad. It lacks alphanumeric keys, function rows, and arrow keys. It must be paired with a separate main keyboard to perform standard typing tasks.
According to their vendor listings, the B31 claims a significantly longer wireless battery life of up to 320 hours. The Q0 HE is rated for up to 56 hours of wireless use with its RGB backlighting turned off.
The specifications for the Keychron B31 explicitly state "Keycaps are not replaceable." This limits customization compared to the Q0 HE, which comes with standard PBT keycaps on a hot-swappable PCB.
Hall Effect switches, like the Gateron double-rail magnetic switches in the Q0 HE, use magnets and sensors instead of physical metal contacts. This allows for features like adjustable actuation points, rapid trigger, and analog input without wear-related chatter.
Yes, both the Keychron B31 and Q0 HE list Mac and Windows support. They include a system toggle switch and compatible keycaps for both operating systems.
No, the Keychron B31 is not hot-swappable. Its product specifications list "Hot-swappable: No," meaning the switches are soldered to the PCB and not designed for user replacement.
The Keychron Q0 HE specifications list a polling rate of 90 Hz when connected via Bluetooth. Its 1000 Hz polling rate is available in both the wired and 2.4 GHz wireless modes.
The Keychron B31 is marketed for silent typing, featuring a scissor mechanism and pre-lubed keys designed for a quiet experience. The Q0 HE's sound profile can be modified with its included foams, but its mechanical switch type may not be as inherently quiet as a scissor mechanism.
Yes, the Keychron Q0 HE supports both QMK open-source firmware and VIA for advanced, real-time key remapping and macro programming, offering deeper customization than the web-based Launcher app alone.
The Keychron Q0 HE features a premium all-metal construction. The vendor description specifies the body is made from 6063 aluminum, and the top case option includes solid copper for a premium feel and acoustics.
No, the Keychron B31 has no backlighting. Its specifications list "Backlight: Non-Backlit." In contrast, the Q0 HE features south-facing RGB LEDs with per-key and mix zone lighting controls.
