Pros and Trade-offs

Your decision hinges on software freedom versus switch variety. The Keychron K5 QMK V2 is the definitive upgrade for enthusiasts, delivering superior firmware customization, a more refined internal build with acoustic foams, and broader layout support. Choose the original Keychron K5 if you specifically want the option for low-profile optical switches and do not require deep programmability, potentially at a lower cost.

Keychron K5 QMK V2

  • +Supports QMK and VIA open-source firmware for extensive key remapping and macros.
  • +Includes enhanced IXPE, EPDM, and latex acoustic foams for a refined typing sound.
  • +PCB mount style and redesigned stabilizers for a more consistent feel.
  • +Offers multiple ISO layout options (DE, Nordic, UK, Swiss, ANSI).
  • +Explicitly lists a 1000 Hz polling rate in wired mode.
  • −Compatible only with specific low-profile mechanical switches (Keychron Milk POM or Gateron), not optical switches.
  • −Full-size layout is not portable.
  • −Uses ABS keycaps, which may develop shine over time.

Keychron K5

  • +Offers a choice between low-profile Gateron mechanical switches and low-profile Keychron optical switches.
  • +Vendor reviews praise its quiet operation and build quality.
  • +Hot-swappable option is available for the optical switch version.
  • +Generally available at a lower price point than the QMK V2.
  • −Lacks QMK/VIA firmware support, limiting software customization.
  • −Uses a tray mount style, which may feel less uniform than PCB mount.
  • −Only lists ANSI layout support, no ISO options.
  • −Vendor reviews note some users experienced issues with Bluetooth stability.
