Keychron C4 HE vs K2 MaxWired Hall Effect vs Wireless 75%

The Keychron C4 HE uses Hall Effect magnetic switches, which detect key presses via magnets rather than physical metal contacts. According to Keychron, this allows for features like adjustable actuation points. The K2 Max uses traditional mechanical switches like the Keychron Super series.

Yes, the Keychron K2 Max supports a wired USB-C connection in addition to its 2.4GHz and Bluetooth wireless modes. Using it wired also allows for configuration via the Keychron Launcher web app.

Both aim to enhance typing feel with sound-dampening foam and PBT keycaps. The C4 HE uses a gasket mount and Cherry profile keycaps, while the K2 Max uses a plate mount and OSA profile keycaps. Preference depends on your desired level of flex and keycap shape.

Yes, both the Keychron C4 HE and K2 Max list Mac and Windows support. The K2 Max specifically mentions including keycaps for both systems and a system toggle switch.

Yes, both keyboards are hot-swappable. The C4 HE supports compatible Hall Effect magnetic switches. The K2 Max supports standard 3-pin and 5-pin MX-style mechanical switches.

Keychron lists the K2 Max as having a 4000mAh battery. The vendor description does not provide an estimated battery life in hours, which will vary based on backlight usage and connection type.

Both have RGB backlighting with over 22 modes. The C4 HE uses north-facing LEDs, which may provide better shine-through for keycap legends. The K2 Max uses south-facing LEDs, which prevent interference with Cherry-profile keycaps and offer a different lighting angle.

A higher polling rate can reduce input lag. The 8000Hz rate on the C4 HE is marketed for competitive gaming where milliseconds count. For general use, the difference from a standard 1000Hz keyboard (like the K2 Max) may be less perceptible.

The C4 HE listing mentions a Type-C cable and a Type-A to Type-C adapter. The K2 Max description does not detail included accessories, but both are pre-built keyboards that should include necessary cables for operation.

Yes, both keyboards support key remapping and macro creation. They are compatible with both the open-source QMK firmware and the Keychron Launcher web app for customization.

The Keychron K2 Max is more portable due to its smaller 75% layout, wireless capability, and slightly lower weight (940g vs 970g). The C4 HE is a larger, wired-only board designed for a stationary setup.
