What will you mostly use it for?
The V3 Ultra takes more categories, particularly for office use, travel, and content creation, due to its longer claimed battery life, lighter weight, and inclusion of a control knob. The K8 HE stands out for modders interested in its unique magnetic switch system and aluminum construction. For gaming and programming, the keyboards tie, offering different paths to high performance: magnetic customization versus ultra-high polling rate.
It's a tie
- The K8 HE offers magnetic switch features like adjustable actuation (0.2-3.8mm), rapid trigger, and analog mode for nuanced control.
- The V3 Ultra provides an 8000 Hz polling rate in both wired and 2.4 GHz wireless modes for minimal input lag.
- Both feature N-key rollover and are listed as supporting Mac and Windows systems.

Keychron K8 HE vs V3 Ultra: your questions
The core difference is the switch technology. The K8 HE uses Gateron Double-Rail magnetic (Hall effect) switches with features like adjustable actuation and rapid trigger. The V3 Ultra uses standard mechanical Keychron Silk POM switches but offers a much higher 8000 Hz wireless polling rate and a gasket mount design.
According to their vendor pages, the V3 Ultra claims a significantly longer battery life. It is rated for up to 660 hours with backlighting off, compared to the K8 HE's listed up to 110 hours. Actual results will vary with usage patterns and lighting settings.
No. The Keychron K8 HE's product description states it is compatible exclusively with Gateron Double-Rail Magnetic Switches. It does not support other magnetic switches or standard mechanical MX-style switches.
The V3 Ultra is hot-swappable for standard 3-pin and 5-pin MX-style mechanical switches. The vendor page lists compatibility with switches from Cherry, Gateron, Kailh, and others, offering broad customization for standard switch types.
Yes, both the K8 HE and V3 Ultra offer 2.4 GHz wireless, Bluetooth, and wired USB-C connectivity. They can both connect to multiple devices, with the K8 HE supporting Bluetooth 5.2 and the V3 Ultra supporting Bluetooth 5.3.
The V3 Ultra is likely better suited for a quiet office. Its gasket mount design, polycarbonate plate, and multiple sound-dampening foam layers are engineered to reduce acoustic resonance. The K8 HE, while also foamed, has an aluminum plate and tray mount which can produce a sharper sound.
The K8 HE uses QMK firmware and is configurable via the Keychron Launcher web app and VIA. The V3 Ultra uses ZMK firmware and is also configured through the Keychron Launcher web app, offering deep key remapping and macro programming for both.
Yes, there is a slight difference. The K8 HE has a primary typing angle of 5 degrees, while the V3 Ultra has a primary angle of 4 degrees. Both offer additional angle adjustments via their feet.
Neither keyboard includes a palm rest in the standard box. However, both Keychron product pages list a silicone palm rest as a separately sold accessory that can be purchased.
No. The K8 HE Special Edition uses OSA profile double-shot PBT keycaps, while its Standard Version uses Cherry profile shine-through PBT. The V3 Ultra uses OSA profile double-shot PBT keycaps. All keycaps are PBT for durability.
No. Adjustable actuation point is a feature specific to the magnetic switch technology in the K8 HE. The mechanical switches in the V3 Ultra have a fixed actuation point determined by the switch's physical design.
