What will you mostly use it for?
The C4 HE takes gaming through its 8000 Hz polling rate, Hall Effect magnetic switches, and adjustable actuation. Office and programming come out close because both boards share QMK, VIA, Launcher support, a 100% layout, and media keys. The K10 V2 wins travel and content creation through Bluetooth 5.2 and a 4000mAh battery, and it edges modding via the DIY kit/barebones option and wide MX switch compatibility. Buyers who never unplug should lean toward the C4 HE, while anyone who wants cable-free use should lean toward the K10 V2.
Pick the Keychron C4 HE
- 8000 Hz polling rate in wired mode, switchable to 1000 Hz or 4000 Hz via the Keychron Launcher app.

Keychron C4 HE vs K10 V2: your questions
No. Keychron lists the C4 HE as a wired keyboard using a Type-C connection, with the 8000 Hz polling rate delivered over that wired link. If you need untethered use, the K10 V2 is the wireless option in this comparison.
Yes. Keychron specifies stable Broadcom Bluetooth 5.2 on the K10 V2, and you can connect it to up to 3 devices and switch among them. A USB Type-C wired connection is also available when you prefer a cable.
The C4 HE runs at 8000 Hz out of the box in Type-C wired mode, per Keychron. You can switch between 1000 Hz, 4000 Hz, and 8000 Hz inside the Keychron Launcher web app.
Both are hot-swappable, but the switch ecosystem differs. The C4 HE takes compatible Hall Effect magnetic switches, while the K10 V2 accepts most 3-pin and 5-pin MX style switches such as Cherry, Gateron, Kailh, and Panda, per Keychron.
The Keychron C4 HE uses a gasket mount with a steel plate and EVA acoustic foam, according to Keychron. The K10 V2 uses a tray mount, and its foam stack includes PET, IXPE, and EPDM layers.
Yes. Keychron lists ISO, ISO-UK, ISO-DE, ISO-ES, ISO-FR, ISO-Nordic, ISO-SW, and ISO-CH layout variants for the K10 V2 alongside ANSI. The C4 HE is listed as ANSI only.
The K10 V2 uses a 4000mAh battery, which Keychron lists as its power source for wireless use. Actual runtime depends on factors such as backlight usage, so Keychron does not publish a single figure for all configurations.
Yes. Both boards list QMK and VIA support, and both work with the Keychron Launcher web app for key remapping and macros. Keychron notes the Launcher requires a recent version of Chrome, Edge, or Opera.
The C4 HE is oriented toward competitive gaming, with an 8000 Hz polling rate, Hall Effect magnetic switches, and adjustable actuation points. The K10 V2 runs at 1000 Hz, per Keychron, and its main edge in gaming is wireless freedom and hot-swappable MX switches.
The C4 HE weighs 970g and measures 30 x 446 x 138 mm, while the K10 V2 weighs 1160g and measures 39 x 440 x 129 mm. Both are full-size 100% layouts, so the difference is modest in practice.
Yes. Keychron lists a DIY kit/barebones option for the K10 V2, which is not offered for the C4 HE. Note that the Black fully assembled non-hot-swap version of the K10 V2 excludes sound-absorbing foam and silicone pad, per Keychron.
Both list screw-in stabilizers, though the C4 HE uses plate-mounted stabilizers and the K10 V2 uses PCB-mounted screw-in steel stabilizers on hot-swap versions. Keychron notes the non-hot-swappable K10 V2 versions mount stabilizers on the plate instead.
