Keychron K2 HE: Specs, Price, Pros & Cons
HE in the name stands for Hall effect, and it brings the three things magnetic switches make possible to a compact wireless Keychron: an actuation point you choose, rapid trigger, and analog input that lets a key act like a joystick axis.
Analog input is the one many magnetic boards leave out. It turns a key into a throttle or a steering input in games that read gradual movement, so pressing halfway means going halfway. Rapid trigger resets a key the moment it starts to rise, which suits quick direction changes in shooters. Onboard profiles keep those settings on the board when it moves to another computer.
The layout keeps the function row and the arrow keys and drops the number pad, which makes it a board you can write on without learning layers. It connects over a cable, a receiver or Bluetooth to three devices, a spread that is less common on magnetic boards than on mechanical ones. The switches sit in hot-swap sockets, the keycaps are PBT, and the case carries sound dampening inside. Cutting the cable shows in the battery rating of 110 h, well short of most wireless keyboards. The front edge also stands high, so plan on a wrist rest for long sessions, and there is no rotary knob.
It sits in a small group: keyboards built to type like an enthusiast board and play like a magnetic one. The buyer it suits spends as many hours in documents as in games, wants the Hall-effect features without a wire, and can live with charging more often. Chasing the lowest possible input lag leads to faster-polling wired boards instead.

How this VS Score was computed
Score 67: each known spec is measured against the median of all keyboards (101 products), then weighted; 50 means level with that median. In classes of six or more, a value beyond the class’s 10th–90th percentile range counts as that limit, so one extreme product cannot set the scale. 63% of the scoreable weight could be used; unknown values, features not applicable to this class and proxies (battery capacity where a rated life exists) add or remove nothing.

Editor’s note
The K2 HE is the most complete Hall-effect specification here for someone who also wants to type on the thing.
It has the full magnetic feature set: adjustable actuation, rapid trigger and true analog input, so keys can act as joystick axes. The 75% layout keeps a function row and arrow keys, which a 60% board makes you learn layers for. Connection is tri-mode: wired, 2.4 GHz and Bluetooth for up to three devices.
Where it differs from the competition is construction. The case and plate are both aluminum with a top mount and screw-in PCB stabilizers, plus sound dampening, the recipe an enthusiast mechanical board uses, applied to a magnetic one. At 965 g it feels planted, and it types like a considered product rather than a gaming peripheral.
One number caps its competitive credentials: polling runs at 1,000 Hz, against 8,000 Hz on the Wooting and the NuPhy. In practice the difference is fractions of a millisecond and invisible to almost everyone, but if you are buying a Hall-effect board specifically to shave input lag, that is the specification to weigh.
Keycaps are PBT, the backlight is per-key RGB, and there is onboard profile storage so settings survive moving between machines.
Buy it if you want magnetic-switch gaming features on a keyboard that is pleasant to write on, wirelessly. Buy the Wooting if the last fraction of a millisecond is the point.

The bottom line
The Keychron K2 HE earns a VS Score of 67, above the median of the 101 keyboards it is measured against (a score of 50 is level with that median).
- Who it’s for
- Players who want magnetic-switch features for games but spend as much time writing, and want to switch wirelessly between three devices.
- Who should look elsewhere
- Players shaving every fraction of latency will want a faster-polling wired board. It is also tall, so plan on a wrist rest.
- The trade-off that matters
- Wireless costs battery. It needs charging far more often than a mechanical board, which matters if the cable was the thing you were escaping.
- The main alternative
- NuPhy WH80: magnetic switches with wireless and a much bigger battery, if you can live without analog axes.
