What will you mostly use it for?
The K5 QMK V2 is the clear choice for gaming, programming, modding, and content creation due to its high polling rate, extensive firmware support, and acoustic enhancements. For general office use, both keyboards are equally capable with their shared low-profile design and wireless features. Neither keyboard has a distinct advantage for travel due to their shared full-size form factor.
Pick the Keychron K5 QMK V2
- The K5 QMK V2 lists a 1000Hz polling rate in wired mode, which the K5 SE's description does not mention.
- The K5 QMK V2 vendor page states its latency is hardly noticeable in competitive games.
- Its PCB mount style may offer a more consistent typing feel compared to the K5 SE's tray mount.

“Genuinely happy with the keyboard. Had a low-profile one from another brand that has been used for 12+ years, and it degraded over time. This K5 feels very good. Still have to get used to the distance between the "primary," arrows, and numpad blocks, but…”
“Got this keyboard so I could keep my K5 Pro at work and this one at home. Both are the RGB version with brown switches, the K5v2 is quieter than the Pro and just as good to use. It also reports battery state over Bluetooth, which is a nice QoL improvement…”

“This is my favorite keyboard. After assembling my desktop pc, I had always felt a little awkward typing on normal sized mechanical keyboards. This keyboard solved that for me. I currently use mine for my desktop, and on the go with my Steam Deck.”
“Found this keyboard while cleaning out my closet and remembered why it's the worst purchase I've ever made. I used it for barely 2 months in total. First, keys started sticking. There were zero replacement parts on their website, so I contacted Keychron…”

Keychron K5 QMK V2 vs K5 SE: your questions
The primary difference is firmware and construction. The K5 QMK V2 supports QMK and VIA for extensive programming, includes multiple acoustic foams, and has a PCB mount. The K5 SE is a more budget-friendly model with a reinforced aluminum top case but lacks advanced firmware support and uses a tray mount.
Yes, both models offer hot-swappable versions. However, they are compatible with different switches. The K5 QMK V2 hot-swap version works with Keychron Milk POM or Gateron/Keychron low-profile mechanical switches. The K5 SE hot-swap version works with low-profile Keychron optical switches or low-profile Gateron mechanical switches.
The K5 QMK V2 is better suited for gaming. Its vendor description explicitly mentions a 1000Hz polling rate in wired mode and states the latency is hardly noticeable in competitive games. The K5 SE's gaming performance is not detailed in the available specifications.
Yes. The K5 QMK V2 vendor description states it is compatible with both Windows and macOS, includes keycaps for both systems, and even has specific multimedia keys for Mac users. The K5 SE is also listed as compatible with Mac and Windows.
Yes, both the Keychron K5 QMK V2 and K5 SE are 100% layout keyboards, which means they include a full number pad.
Both keyboards use low-profile switches. The K5 QMK V2 features Keychron Milk POM switches (linear, tactile, or clicky). The K5 SE offers low-profile Gateron mechanical switches or low-profile Keychron optical switches in various linear, tactile, and clicky variants.
The K5 QMK V2 is designed with enhanced acoustics in mind. Its vendor description highlights the inclusion of IXPE acoustic foam, EPDM foam, and latex foam to improve sound and comfort, suggesting a more refined typing sound profile compared to the K5 SE.
Yes, but with limitations. Both keyboards use low-profile keycaps with specific stems. The K5 QMK V2 vendor page shows optional low-profile PBT keycap sets for sale, indicating replaceability. The K5 SE uses MX-style stems on its low-profile switches, which should allow for compatibility with other low-profile MX-stem keycaps.
According to its specification list, the K5 SE has a 2000mAh battery. With the backlight off, it can last up to 90 hours. With RGB backlight at the lowest brightness, battery life is up to 30 hours. Lab results may vary with actual use.
The available information for the K5 SE does not mention any software or firmware for key remapping, macro programming, or QMK/VIA support. Its customization appears limited to the hot-swappable switches and adjustable backlighting.
The Keychron K5 QMK V2 offers more layout options. Its metadata lists support for ISO-DE, ISO-Nordic, ISO-UK, ISO, and ANSI. The K5 SE is listed with ANSI and JIS layouts only.
Neither keyboard includes a wrist rest in the standard package. However, the K5 QMK V2 vendor page shows a separate Keychron Silicone Palm Rest for low-profile keyboards as a frequently bought together item.
