The GMMK 3 Pro HE Wireless 65% is a compact gaming mechanical keyboard built on a standard profile with a gasket mount and a 65% layout. It supports wireless and wired connectivity through Bluetooth, 2.4GHz wireless, and USB, and delivers a polling rate of 8000 Hz. The battery is rated for up to 24 hours of use, and the keyboard includes a detachable cable. Physical dimensions come in at 335 mm wide, 125 mm deep, and 42.5 mm thick, with a total weight of 1810 g. The keyboard is not designed for Mac, covers a 2-year warranty period, and is not USB passthrough-equipped.
The keyboard features a plastic and aluminum case paired with an aluminum plate, and is available in both white and black colorways. It includes a backlit layout with full RGB lighting, giving users control over per-key illumination. A wrist rest is included in the box, and adjustable feet allow for tilting the board to a preferred typing angle.
This keyboard uses the Glorious Fox HE, a Hall effect switch with a linear feel and a light actuation force of 28 g. The actuation distance is adjustable between 0.1 mm and 4 mm, with a total travel distance of 4 mm, allowing for a wide range of sensitivity settings. The switches are hot-swappable, making it straightforward to replace them without soldering.
The keyboard supports rapid trigger, dual actuation, adjustable actuation, and analog input, making it well-equipped for precision-sensitive use cases where fine control over key behavior matters. N-key rollover is also present, ensuring every simultaneous keypress is registered. On the other hand, the board does not include USB passthrough, a display, or support for QMK, ZMK, or VIA firmware.
The keyboard uses an ANSI (United States) layout with a standard key arrangement and OEM profile keycaps made from double-shot PBT. Media functions are accessible via the Fn key rather than dedicated keys, and a rotary dial is included on the board. The layout follows standard keycap sizing, making keycap replacement straightforward.
