Compare Keychron K3 Max SE vs K3 V2 Differences Side by Side

This comparison is for buyers who want a low-profile 75% keyboard but are torn between additional features and lower cost. The decision is difficult because both keyboards share the same core DNA: a compact 75% layout, low profile design, hot-swappable switches, and a 1550mAh battery. The K3 Max SE is an iterative upgrade that adds 2.4 GHz wireless, QMK/VIA support, a wooden side frame, and PBT keycaps. The K3 V2, on the other hand, is the older model that remains relevant by offering more layout standards and a lower price point. The main trade-off is between modern connectivity and customization versus cost savings and layout variety.

Pros and Trade-offs

If you value low-latency wireless performance and the ability to customize every key function, the Keychron K3 Max SE is the clear choice. Its 2.4 GHz connectivity, QMK/VIA support, and PBT keycaps provide a superior typing and gaming experience. However, if your priority is budget savings and you need a specific ISO layout for your region, the Keychron K3 V2 remains a functional low-profile option, though it compromises on customization and wireless performance.

Keychron K3 Max SE

  • +Supports 2.4 GHz, Bluetooth 5.2, and wired connections with a 1000 Hz polling rate on 2.4 GHz and wired modes.
  • +Full QMK and VIA support for deep key remapping, macros, and custom firmware.
  • +PBT keycaps with double-shot molding for oil resistance and long-lasting legends.
  • +Includes multiple sound dampening layers (EPDM foam, bottom case acoustic foam, PET film, and latex foam) for a quieter typing experience.
  • −Heavier weight at 566g compared to the K3 V2, though the K3 V2's exact weight is not provided.
  • −Only available in ANSI layout, lacking the ISO options found on the K3 V2.
  • −Generally priced higher than the K3 V2, reflecting its premium feature set.

  • +Features multi-media keys out of the box, which are not explicitly mentioned for the K3 Max SE.
  • +Comes with 12 extra keycaps and a dust cover according to the vendor.
  • −Lacks 2.4 GHz connectivity, relying solely on Bluetooth and wired modes.
  • −Does not support QMK or VIA firmware, limiting customization to what is programmed at the factory.
  • −Uses ABS keycaps which are prone to developing shine over time compared to PBT.
  • −Only has Bluetooth 5.1 support, one generation behind the K3 Max SE's Bluetooth 5.2.

Which Keyboard Is Better for Your Needs?

The K3 Max SE wins out in gaming, programming, modding, and content creation due to its superior connectivity and customization features. It offers a 1000 Hz polling rate, 2.4 GHz wireless, QMK/VIA support, and multiple sound dampening foams. For office and travel, the two are essentially tied, as both share similar form factors and battery life. The K3 V2 remains a viable option largely due to its lower price and wider range of layout standards, but it cannot match the Max SE's feature set for demanding users.
