Is the Keychron C4 HE wireless?

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.

Does the Keychron K10 V2 have Bluetooth?

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.

What polling rate does the Keychron C4 HE use?

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.

Can I hot-swap switches on both keyboards?

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.

Which keyboard has a gasket mount?

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.

Does the Keychron K10 V2 come in ISO layouts?

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.

How long does the K10 V2 battery last?

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.

Do both keyboards support QMK and VIA?

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.

Which is better for gaming, the C4 HE or K10 V2?

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.

What is the difference in weight and size?

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.

Is the K10 V2 available as a barebones kit?

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.

Which keyboard has better stabilizers?

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.

Keychron C4 HE vs K10 V2: Wired 8K Hall Effect vs Wireless QMK

Compare Keychron C4 HE vs K10 V2 Differences Side by Side

Both keyboards are full-size Keychron models with hot-swap sockets, QMK and VIA support, media keys, and dampening foam, which makes the choice less obvious than the layouts suggest. The decision comes down to connectivity and switch technology. The C4 HE is wired only and pairs an 8000 Hz polling rate with Hall Effect magnetic switches and a gasket mount, while the K10 V2 adds Bluetooth 5.2, a 4000mAh battery, and ISO layout variants on a tray mount. This comparison is for buyers deciding between maximum wired responsiveness and wireless flexibility at a similar full-size footprint.

Pros and Trade-offs

Choose the Keychron C4 HE if your priority is wired responsiveness, with its 8000 Hz polling rate, Hall Effect magnetic switches, and gasket mount. Choose the Keychron K10 V2 if you need Bluetooth 5.2, a 4000mAh battery, ISO layout variants, or a DIY kit/barebones path. The gasket versus tray mount and wired versus wireless split is the core decision, since both boards share QMK, VIA, media keys, and a full-size layout.
