Keychron K4 HE
Magnetic
Build quality in the top 10% of 96% boards under $150.
- Magnetic switches offer adjustable actuation and Rapid Trigger.
- 2.4 GHz, Bluetooth, and wired connectivity are listed, with 1000 Hz polling in 2.4 GHz and wired modes.
- Dynamic Keystrokes supports up to four actions per key based on press depth.
- Magnetic switches only. Standard MX switches will not fit.
- North-facing LEDs. Cherry-profile keycaps can hit the switch housing.
- Compact full-size layout. The numpad is present, the gaps of a full-size board are not.
Pick the K2 Pro if a smaller layout and broad compatibility with common MX-style mechanical switches matter more than dedicated magnetic gaming features. Choose the K4 HE if you want adjustable actuation, Rapid Trigger, and 2.4 GHz connectivity, and are comfortable with its larger layout and more limited magnetic switch choices. Check the specific K4 HE layout and switch version before buying.

What will you mostly use it for?
The K4 HE has the clearer gaming edge because its magnetic switches add adjustable actuation, Rapid Trigger, and layered key actions. The K2 Pro suits buyers who want a smaller board, conventional mechanical switches, or wider switch-swap options. For office use and travel, its 75% layout is the main advantage, though neither model is especially light by the listed weights. Both offer QMK and VIA support, so the choice for programming and customization turns on layout and switch flexibility.
Pick the Keychron K4 HE
- The K4 HE has magnetic switches with adjustable actuation and Rapid Trigger.
- Its 2.4 GHz connection supports a 1000 Hz polling rate, as does wired mode.
- Dynamic Keystrokes can assign up to four actions to a key based on press depth.

Keychron K2 Pro vs K4 HE: your questions
The K4 HE has magnetic switches with adjustable actuation, Rapid Trigger, and Dynamic Keystrokes. It also supports 1000 Hz polling in wired and 2.4 GHz modes, while the K2 Pro’s listed polling rate is 1000 Hz without a listed 2.4 GHz connection.
The K2 Pro is a 75% keyboard, and the K4 HE is a 96% keyboard. The K2 Pro is the smaller layout option, while the K4 HE includes a larger layout.
Rapid Trigger is listed for the K4 HE, not the K2 Pro. The K2 Pro uses hot-swappable mechanical switches and supports QMK and VIA.
Yes, the K2 Pro is hot-swappable. Keychron says its sockets support almost all 3-pin and 5-pin MX-style mechanical switches without soldering.
No. Keychron says the Ultra-fast Lime version supports only Keychron Ultra-fast Lime magnetic switches, and the Gateron Double-Rail version supports only Gateron Double-Rail magnetic switches.
Yes, the K4 HE supports adjustable actuation for its magnetic switches. The vendor gives different actuation ranges for the Lime and Gateron Double-Rail switch versions, so check the exact version before purchase.
Both keyboards list QMK and VIA support. Their vendor descriptions also identify Keychron Launcher for key remapping and macros.
The K4 HE lists 2.4 GHz, Bluetooth, and wired connectivity. The K2 Pro lists Bluetooth and wired connectivity, but not 2.4 GHz.
Keychron lists up to 110 hours of wireless use for the K4 HE and notes that actual results may vary. Both keyboards list a 4000 mAh battery.
The K2 Pro is listed at 1070 g, while the K4 HE is listed at approximately 1090 g. Their listed weights are close, so layout size is the more notable portability difference.
The K2 Pro metadata lists ISO and ANSI standards, and its vendor page describes several ISO versions. The K4 HE’s main vendor specifications list ANSI, while its page points buyers to a separate ISO collection.
The K2 Pro offers broader mechanical-switch flexibility, with Keychron specifying support for almost all 3-pin and 5-pin MX-style switches. The K4 HE is hot-swappable too, but magnetic switch compatibility is limited to the matching switch family for each version.
