What will you mostly use it for?
The K3 Max SE wins the gaming and travel categories thanks to its 2.4 GHz connectivity and much lighter weight. The K2 Pro takes programming and modding due to its standard switch compatibility, steel plate, and screw-in stabilizers. Office and content creation end in a tie because both keyboards offer the same core QMK/VIA flexibility and dual-OS support, differing primarily in shape and battery capacity.
Pick the Keychron K3 Max SE
- The K3 Max SE offers a dedicated 2.4 GHz connection with 1000 Hz polling on wireless and wired modes, ideal for low-latency gaming.
- Weighs 566g, making it easier to move for LAN events or desktop adjustments.
- The vendor notes that the K3 Max SE's 2.4 GHz wireless is built for 'blazing-fast responsiveness' in intense gameplay.

“I have been using the keychron K2 V2 for more than a year so when this came out, I knew I had to get this. and boy I never imagined the smoothness and thock on this thing. I replaced the brown switches with lavender purples and it feels even better.”

Keychron K2 Pro vs K3 Max SE: your questions
The K3 Max SE is better suited for gaming due to its 2.4 GHz wireless connection, which provides lower latency than Bluetooth. It also maintains a 1000 Hz polling rate in both 2.4 GHz and wired modes, as stated by the vendor.
Yes, the K2 Pro ships with keycaps for both macOS and Windows, and the vendor confirms compatibility with both operating systems. The keyboard includes Mac-specific multimedia and function keys for a seamless experience.
Yes, the K3 Max SE supports both QMK firmware and the Keychron Launcher web app for customization. The vendor highlights that you can remap keys, create macros, and adjust backlighting through these tools.
It depends on the version you choose. The hot-swappable versions allow you to change switches without soldering, accepting most 3-pin and 5-pin MX-style switches. However, the Black Fully Assembled version is not hot-swappable and lacks the sound-dampening foam.
The K2 Pro has a steel plate and a case available in aluminum or ABS plastic, offering a heavier build. The K3 Max SE uses an aluminum plate with an ABS plastic body and wooden side frames, resulting in a lighter and more unique aesthetic.
The K3 Max SE is significantly more portable, weighing just 566g compared to the K2 Pro's 1070g. Its ultra-slim low-profile design also makes it easier to slide into a bag, as the vendor emphasizes its 'lightweight' and 'ultra-slim' characteristics.
No, the K3 Max SE uses low-profile switches and LSA profile keycaps. The vendor only lists low-profile keycap sets as compatible accessories, and standard MX keycaps would not fit properly on these switches or the keyboard's shorter stem height.
No, the K2 Pro does not support 2.4 GHz wireless. It offers Bluetooth and wired USB-C connectivity, as stated in the specs. For lower-latency wireless, you would need to use the wired connection.
The K2 Pro has screw-in PCB stabilizers, which provide more stability and less wobble on large keys compared to the K3 Max SE's plate-mounted stabilizers. The vendor notes the K2 Pro's stabilizers are designed for a 'smoother typing experience' with less wobbliness.
The K2 Pro has a larger 4000mAh battery, while the K3 Max SE uses a 1550mAh battery. The vendor states the K3 Max SE offers up to 120 hours of wireless working time; the K2 Pro's battery capacity suggests longer endurance, though exact hours are not specified in the provided data.
No, the K3 Max SE is only available in ANSI layout. If you need an ISO layout, the K2 Pro offers UK, German, Nordic, Swiss, French, and Spanish options, making it the better choice for users in those regions.
The K2 Pro is easier to mod due to its standard MX switch compatibility and abundance of aftermarket parts. It also comes in a barebones version, and its steel plate and screw-in stabilizers provide a mod-friendly platform. The K3 Max SE's low-profile nature limits switch and keycap choices.
