What will you mostly use it for?
The K2 Max is the more feature-rich fit for gaming, office work and hands-on modification, particularly if 2.4 GHz wireless or its acoustic construction matters. For travel, the K3 Pro is the lighter and slimmer choice. Programming is a close match because both boards support QMK and VIA, but the K2 Max adds 2.4 GHz and its listed construction features. Either can serve content workflows, with the choice mainly between the K2 Max's connection and build features and the K3 Pro's low profile.
Pick the Keychron K2 Max
- The K2 Max supports 2.4 GHz wireless at a listed 1000 Hz polling rate; the K3 Pro does not list 2.4 GHz connectivity.
- The K2 Max vendor description specifies 1000 Hz polling in both 2.4 GHz and wired modes.

Keychron K2 Max vs K3 Pro: your questions
The K2 Max adds 2.4 GHz wireless, layered acoustic foam and a steel plate. The K3 Pro has a low-profile design, weighs 525g and is listed in ISO-FR and ISO-ES layouts.
Yes. Keychron lists 2.4 GHz, Bluetooth and wired connectivity for the K2 Max, and specifies 1000 Hz polling in 2.4 GHz and wired modes.
The K3 Pro is listed with Bluetooth and wired connectivity, not 2.4 GHz. Its vendor description specifies 1000 Hz polling in wired mode.
The Keychron K3 Pro is listed at 525g, while the K2 Max is listed at 940g. The K3 Pro also has a lower-profile design.
No, the K3 Pro compatibility details specify low-profile switches and keycaps only, so standard MX keycaps will not fit. The K2 Max vendor says its hot-swap version supports almost all 3-pin and 5-pin MX-style mechanical switches.
Both are listed in ANSI, ISO-DE, ISO-Nordic, ISO-SW and ISO-UK layouts. ISO-FR and ISO-ES are listed for the K3 Pro but not the K2 Max; the K3 Pro is also listed in JIS.
Both have hot-swappable versions. Keychron says the K2 Max hot-swap version accepts almost all 3-pin and 5-pin MX-style mechanical switches, while the K3 Pro hot-swap version is limited to low-profile Gateron mechanical switches.
The K2 Max vendor description names multiple acoustic foam layers, including IXPE, PET and EPDM, along with a steel plate. The K3 Pro description does not specify those foam layers.
Both list Mac/Windows support and include keycaps for both systems in their vendor descriptions. The K2 Max has a system toggle, while the K3 Pro description says users can configure different keymaps for Mac and Windows.
Both list QMK and VIA support. Keychron also describes key remapping and macro commands through its Launcher web app for each board.
Compatibility details warn that south-facing LEDs on the K2 Max can leave shine-through legends dark, and some sculpted keycaps may clip the LEDs. The K3 Pro also has south-facing LED variants with that warning, and its north-facing LEDs can interfere with Cherry-profile keycaps.
The K2 Max is listed with a 4000mAh battery, while the K3 Pro is listed with a 1550mAh battery. Battery life is not specified here, so capacity alone does not establish how long either board runs between charges.
