What will you mostly use it for?
The K3 Max wins for office use and travel due to its slim, lightweight design. The Q3 Max is the clear choice for modding and has an edge for programming and content creation with its TKL layout and knob option. For gaming, both are technically matched on core specs, leaving the choice to a preference for low-profile versus standard key feel. Content creators may value the Q3 Max's programmable knob and heftier build.
It's a tie
- Both have a 1000 Hz polling rate in 2.4 GHz and wired modes for low latency.
- Both feature N-key rollover for simultaneous key presses.
- The Q3 Max's heavier aluminum build may feel more stable, while the K3 Max's low-profile switches offer a different key travel.

“Noce keyboard, i appreciate the level of customization QMK provides. One thing was little disappointing - the tactile feeling comparing to K3. Other than that its very good kb!”
“I sold my k3 pro and got this. The one I got drops connection intermittently or doesn't type or respond right away. It sounds nice, but stiff reds are not as pleasant to type on as previous keyboards reds. I really thought I ordered hotswap RGB max but seems…”

Keychron K3 Max vs Q3 Max: your questions
Both keyboards are listed as having Mac/Win support and include keycaps for both operating systems. The K3 Max's vendor description specifically highlights its Mac layout and suitability for users transitioning from an Apple Magic Keyboard. The Q3 Max also includes system-specific keycaps and a system toggle.
No. According to the manufacturer's description, the K3 Max is only compatible with Gateron and Keychron low-profile mechanical switches. It cannot accept standard-profile MX-style switches due to its low-profile design and switch housing.
The Q3 Max uses a double-gasket mount, where the plate is suspended on soft gaskets to absorb vibration and create a softer, more cushioned typing feel. The K3 Max uses a plate mount, where the plate is fixed more rigidly to the top case, typically resulting in a firmer, more direct feedback.
Keychron's specifications for the Q3 Max state a battery life of up to 180 hours with the backlight off, and up to 100 hours with RGB lighting at its lowest brightness. This is enabled by its large 4000mAh battery.
Yes, both the K3 Max and Q3 Max offer a 1000 Hz polling rate when using their 2.4 GHz wireless dongle or a wired USB-C connection. Their vendor pages note the polling rate drops to 90 Hz when in Bluetooth mode.
Both have sound-dampening features. The K3 Max includes IXPE and latex foam. The Q3 Max features a more comprehensive set of acoustic foams (IXPE, PET, Latex) and a double-gasket design aimed at reducing metal resonance. The Q3 Max's construction likely offers a deeper, more muted sound signature.
Yes. Both the K3 Max and Q3 Max support QMK and VIA firmware, allowing for extensive key remapping, macro creation, and lighting control through the Keychron Launcher web app or compatible software.
The K3 Max comes with low-profile LSA (Low-profile Spherical-Angled) keycaps. The Q3 Max offers a choice between KSA (a taller profile) keycaps or OSA side-printed shine-through keycaps, depending on the variant purchased.
Yes. The vendor description for the Q3 Max states you can reprogram the knob's function using the Keychron Launcher web app, allowing it to control volume, scrolling, or other macros.
The Keychron Q3 Max features south-facing RGB LEDs. The K3 Max uses north-facing RGB LEDs. South-facing LEDs are often preferred as they prevent interference with certain Cherry-profile keycaps.
Yes, both product listings include screw-in stabilizers as a feature. The Q3 Max's page specifically mentions PCB-mounted screw-in stabilizers for less wobble on larger keys.
