- Offers a low-profile design with adjustable typing angles for ergonomic comfort.
- Explicitly compatible with Windows, macOS, and Linux, and includes keycaps for both Mac and Windows layouts.
- Uses north-facing RGB LEDs with shine-through ABS keycaps, which may limit compatibility with some aftermarket keycap sets.

What will you mostly use it for?
The Keychron K5 QMK V2 wins in most categories due to its strong combination of programmability, cross-platform compatibility, and ergonomic low-profile design. It is the clear choice for programmers, office users who switch between Mac and Windows, and modders. The Ducky Zero 6108 remains a competent, more traditionally styled full-size keyboard. Its advantages include PBT keycaps and a 2.4 GHz wireless dongle, but it lacks the software and layout flexibility of the Keychron.
Pick the Keychron K5 QMK V2
- The Keychron K5 has a specified 1000 Hz polling rate in wired mode, which the Ducky's listing does not mention.
- The K5's vendor page states its latency is 'hardly noticeable even in competitive games'.
- Both offer N-key rollover and hot-swap capabilities for switch customization.

“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…”

Ducky Zero 6108 vs Keychron K5 QMK V2: your questions
The Keychron K5 QMK V2 is explicitly designed for Mac compatibility. Its vendor page states it includes Mac-specific keycaps and multimedia key layouts, and it is compatible with macOS. The Ducky Zero 6108's vendor description states it is not Mac compatible.
No. The Keychron K5 QMK V2 hot-swap version is listed as compatible only with specific low-profile mechanical switches, such as Keychron Milk POM or Gateron/Keychron low-profile switches. It does not support standard MX-style switches due to its low-profile design.
User reviews for the Ducky Zero 6108 mention a lack of available software to modify RGB lighting or other settings. The vendor description does not list any companion software, suggesting control is limited to onboard shortcuts.
QMK and VIA support allows for deep, open-source firmware customization. You can remap any key, create complex macros, and adjust lighting effects through a web-based app (Keychron Launcher) without installing software, offering nearly limitless programmability.
Based on the listed specifications, the Ducky Zero 6108 has a larger 2500mAh battery compared to the Keychron K5's 2000mAh battery. This suggests the Ducky may have a longer battery life, though actual runtime depends on usage patterns like backlighting and wireless mode.
Yes. The Ducky Zero uses a standard MX stem and Cherry profile keycaps, making it compatible with many aftermarket sets. Its south-facing RGB LEDs also prevent interference with thicker keycaps, offering broader compatibility.
The Keychron K5's vendor page highlights a 1000 Hz polling rate in wired mode and states the latency is 'hardly noticeable even in competitive games.' It also features N-key rollover. This makes it a capable option for gaming, especially in wired mode.
Low profile refers to a keyboard with slimmer switches and keycaps, resulting in a thinner overall board. Keychron states the K5 uses switches that are 33% slimmer than standard ones, making it an 'ultra-slim' keyboard designed for ergonomics and portability.
The Keychron K5 QMK V2 is likely more portable due to its low-profile, ultra-slim design, which typically reduces weight and thickness. Both are full-size 108-key keyboards, so neither is compact, but the K5's lower height makes it easier to slip into a bag.
Yes, both the Ducky Zero 6108 and the Keychron K5 QMK V2 feature a USB-C port for wired connectivity and charging, as listed in their specifications and vendor descriptions.
The Ducky Zero 6108 includes PU bottom foam, according to its vendor page. The Keychron K5 QMK V2 lists multiple foam layers: IXPE acoustic foam, EPDM foam, and latex foam for enhanced sound and typing feel.
No. The Keychron K5 QMK V2 only supports connectivity via Bluetooth and a wired USB-C cable. It does not include or support a 2.4 GHz wireless dongle, unlike the Ducky Zero 6108 which offers that option.
