Chilkey ND75 LP vs Keychron K3 V3: your questions
The Chilkey ND75 LP is better for wireless gaming because it includes a 2.4GHz wireless mode with a 1000Hz polling rate. The Keychron K3 V3 only supports Bluetooth and wired connections, with its vendor page specifying a 90Hz polling rate in Bluetooth mode.
No. The Chilkey ND75 LP is not compatible with QMK or VIA firmware according to its vendor specifications. It is programmable through Chilkey's own proprietary software instead.
Yes. The Keychron K3 V3 is compatible with both macOS and Windows. Its vendor description notes it includes keycaps for both operating systems and allows configuration of different keymaps for each.
Switch compatibility may be limited. A user review states the hot-swap sockets on the Chilkey ND75 LP do not appear to be compatible with common low-profile switches from Kailh, Cherry, or Gateron. It comes pre-built with Aster linear switches.
The Chilkey ND75 LP has a larger 3600mAh battery, which should provide longer wireless usage between charges compared to the Keychron K3 V3's 1550mAh battery. Actual runtime depends on usage patterns like RGB lighting and connection type.
Yes, but with specific compatibility. The vendor page states the hot-swappable version of the K3 V3 is compatible with Keychron Milk POM switches or Gateron/Keychron low-profile mechanical switches. It notes that QMK does not support low-profile optical switches.
The Keychron K3 V3 is the clear choice. It is available in multiple ISO layouts including UK, German, Swiss, and Nordic. The Chilkey ND75 LP is only listed with an ANSI (US) layout.

The Chilkey ND75 LP includes five layers of sound dampening foam. The Keychron K3 V3 vendor description mentions it uses advanced IXPE acoustic foam, EPDM foam, and latex foam for enhanced acoustics and typing comfort.
Yes, both offer adjustable angles. The Keychron K3 V3 provides three adjustable angles (2.5°, 4.2°, 6.5°). The Chilkey ND75 LP has a fixed 6.5° to 7° typing angle according to its specifications and vendor description.
The Keychron K3 V3 has a specified weight of 540g and dimensions, making its portability quantifiable. While the Chilkey ND75 LP's weight is not listed, its full aluminum case and larger battery may make it heavier, potentially affecting portability.
