Keychron K2 HE (75%/Magnetic Hall Effect/Tri-Mode Wireless + Wired/Hot-Swappable/8000Hz Polling) Review
For anyone typing "wireless Hall Effect keyboard" into a search bar, the Keychron K2 HE answers directly — magnetic switches with adjustable actuation, but untethered over Bluetooth or 2.4GHz.
This is the board we'd point to first if wireless matters more to you than the extra 8000Hz-wired polling rate other Hall Effect boards advertise, since almost nobody actually plays wired-only anymore.
Hall Effect Goes Wireless
Most magnetic-switch boards are wired-only to protect their 8000Hz polling claims; the K2 HE keeps the adjustable actuation and Rapid Trigger while adding Bluetooth and 2.4GHz, a real trade some buyers will happily take.
Compact 75% Footprint
An 84-key layout keeps arrow keys and a small function column without the bulk of a full TKL board, useful on smaller desks where the extra few centimeters actually matters.
Comparison to Alternatives
Against the Wooting 60HE+, that board drops to 60% and is wired-only, trading portability and battery for a marginally more mature actuation curve; the K2 HE is the pick if you specifically want to also use the board away from a desk. Against Keychron's own Q1 HE, the K2 HE is plastic and wireless where the Q1 HE is aluminum and wired-only — pick based on whether cable-free matters more than case heft.

Best for

- Laptop users who travel with their keyboard.
- Buyers who want one board for both gaming and daily typing.
Not for
