What will you mostly use it for?
The K15 Max has the edge for gaming and content creation, particularly for buyers who want its Alice layout or 2.4 GHz connection. Its acoustic foam and broader stated switch compatibility for the hot-swappable version also make it the stronger fit for office typing and switch experimentation. The K3 Pro is the more travel-friendly choice based on its lower weight and smaller listed dimensions. Programming is a close call, with QMK and VIA on both boards and different layout options to consider.
Pick the Keychron K15 Max
- The K15 Max supports 2.4 GHz wireless with a stated 1000 Hz polling rate.
- Both list a 1000 Hz polling rate, but the K3 Pro specifies that rate for wired mode.

Keychron K15 Max vs K3 Pro: your questions
The K15 Max has an Alice 75% layout and supports 2.4 GHz, Bluetooth, and wired connections. The K3 Pro has a conventional low-profile 75% layout and is offered in ISO and JIS variants.
Yes, the K15 Max lists 2.4 GHz, Bluetooth, and wired connectivity. Its specifications state a 1000 Hz polling rate, and Keychron's description identifies that rate for 2.4 GHz and wired modes.
The K3 Pro is listed with Bluetooth and wired connectivity, not 2.4 GHz. Keychron's description specifies a 1000 Hz polling rate for wired mode.
The K3 Pro is listed at 525g, while the K15 Max is listed at 700g. The K3 Pro also has smaller listed dimensions, which may suit buyers prioritizing a more compact carry.
Yes, the K15 Max is listed with an Alice ergonomic layout and Keychron describes it as a 75% Alice keyboard. Choose it if that split, angled layout is a priority.
Yes, the K3 Pro is listed in ISO and several ISO variants, including ISO-UK, ISO-DE, ISO-FR, and ISO-Nordic. JIS and ANSI are also listed.
No, both are specified for low-profile switches and keycaps, and standard MX keycaps will not fit. Check that replacement caps are designed for the relevant low-profile keyboard.
Both are listed as hot-swappable, though Keychron describes hot-swapping as an option for particular versions. The K15 Max vendor description names Gateron and Keychron low-profile mechanical switches, while the K3 Pro description specifies Gateron low-profile mechanical switches.
The K15 Max is listed with a 2000mAh battery, compared with 1550mAh for the K3 Pro. Battery capacity alone does not establish how long either keyboard will run between charges.
Both list QMK and VIA support. Keychron's descriptions also mention using its Launcher web app for key customization, remapping, and macros.
The K3 Pro compatibility notes warn that Cherry-profile keycaps can hit the switch housing on north-facing LED versions. South-facing LED versions have separate caveats: shine-through legends stay dark, and some sculpted caps can clip the LED.
The K15 Max is a sensible choice if you want an Alice layout and the IXPE and latex foam named in Keychron's description. The K3 Pro may suit you better if you need an ISO layout or place greater weight on its lower listed weight.
