Keychron B6 Pro vs K6 ProUltra-Slim Full-Size vs Compact Custom

Both keyboards offer Mac layout support and compatibility. The B6 Pro's product description specifically states it provides the same multimedia and function key functions as Apple keyboards for Mac users. The K6 Pro also includes keycaps for both macOS and Windows. Both can be configured for Mac use via the Keychron Launcher.

No. The product metadata and description for the Keychron B6 Pro do not list hot-swappable sockets as a feature. The switches are not designed to be user-replaceable without soldering. The K6 Pro, in contrast, is explicitly listed as hot-swappable.

No. The Keychron K6 Pro is a 65% layout keyboard. This compact size removes the numpad, function row, and dedicated navigation cluster to save desk space. The B6 Pro is a full-size 100% keyboard and includes a numpad.

The Keychron B6 Pro is listed with a 1200mAh battery, and its manufacturer claims up to 1200 hours of use on a single charge. The K6 Pro has a larger 4000mAh battery, but its product description does not provide a comparable runtime claim. Therefore, based on available information, the B6 Pro has a stated longer battery life.

The K6 Pro is designed for a premium typing experience. Its product listing mentions an upgraded typing experience with sound-absorbing foam, a silicone dampening pad, a steel plate, and pre-lubed K Pro switches. It also features screw-in stabilizers and OSA profile PBT keycaps, which contribute to a stable and comfortable feel.

The B6 Pro uses an ultra-slim, low-profile design with a fixed 3° angle and likely low-profile switches, aiming for a laptop-like typing experience. The K6 Pro is a traditional mechanical keyboard with standard-height switches, a thicker case, adjustable typing angles, and a focus on acoustic and tactile customization through its build materials and hot-swap capability.

Yes, both keyboards support the Keychron Launcher web app for key remapping and macro creation. Additionally, the K6 Pro supports the open-source QMK firmware and VIA software, which offer even more advanced and granular programming capabilities beyond what the Launcher may provide.

The Keychron B6 Pro is more portable by the numbers. It is significantly lighter at 623g versus 890g for the K6 Pro, and it has a much thinner profile at 5mm. However, the B6 Pro is a full-size keyboard, so it takes up more desk area despite being thinner and lighter.

The product metadata confirms the B6 Pro has RGB lighting with north-facing LEDs. The vendor description does not emphasize this feature, but the technical specification lists it. The K6 Pro offers both white backlight and RGB versions with south-facing LEDs.

While the exact contents are not fully itemized, the K6 Pro product page mentions it comes with OSA profile double-shot PBT keycaps and pre-lubed K Pro switches in the assembled version. It also lists a barebone version available without switches and keycaps. The page shows optional accessories like palm rests, switch sets, and coiled cables.

The B6 Pro uses mechanical switches, as listed in its metadata with Linear, Tactile, and Clicky options. However, they are low-profile mechanical switches, which are different in height and travel from the standard MX-style switches found in the K6 Pro. The typing feel will differ significantly between the two models.
