Glorious GMMK 3 Pro HE Wireless 75%

Manufacturer: Glorious

The Glorious GMMK 3 Pro HE Wireless 75% is a compact 75% layout gaming keyboard that combines wireless flexibility with a gasket-mount construction for a more cushioned typing feel. It connects via Bluetooth, 2.4GHz wireless, or USB, and ships with a wrist rest and detachable cable included. The case is built from a combination of plastic and aluminum in either black or white, and the aluminum plate gives the board added rigidity beneath the keycaps.

At the heart of the GMMK 3 Pro HE are Glorious Fox HE Hall effect switches with a linear feel, an actuation force of 28 g, and an adjustable actuation range spanning 0.1 mm to 4 mm. This enables features like rapid trigger, dual actuation, and analog input, all of which can be tuned to preference. The keyboard runs at up to 8000 Hz polling rate, supports full NKRO, and uses PBT double-shot keycaps in an OEM profile on a standard ANSI layout. A rotary dial and per-key RGB lighting round out the feature set, while battery life is rated at 24 hours on wireless.

Pros
  • Actuation point is adjustable from 0.1 mm to 4 mm, with rapid trigger and dual actuation support for precise per-key customization
  • Connects via Bluetooth, 2.4GHz wireless, and USB, offering flexible setup options without being tied to a single connection method
  • Hot-swappable Hall effect switches allow for switch replacement without soldering
  • Gasket mount construction provides a softer, more cushioned typing feel compared to tray or top-mount designs
  • Includes a wrist rest and adjustable feet out of the box, adding ergonomic utility without requiring extra accessories
  • Full N-key rollover ensures every simultaneous keypress is accurately registered
Cons
  • At 1810 g, the keyboard is notably heavy for a 75% form factor, which may limit portability
  • Battery life is rated at 24 hours, which may require frequent recharging in wireless use
  • No support for QMK, ZMK, or VIA, restricting open-source firmware customization options
  • Media functions are only accessible via the Fn key, with no dedicated media keys on the layout
  • No USB passthrough port is available on the keyboard itself
Who is this for?

This keyboard is a strong fit for competitive or precision-focused gamers who benefit from adjustable actuation and rapid trigger functionality, as the Hall effect switches allow fine-tuned control down to 0.1 mm. The 8000 Hz polling rate and full NKRO support make it well-suited for users who demand consistent, low-latency input registration. Those who prefer a wireless setup at a desk will also find value in the tri-mode connectivity and the included wrist rest, which adds comfort during extended sessions.

Who is this NOT for?

At 1810 g, this is not a practical choice for users who frequently travel or need a portable, lightweight keyboard. The 24-hour battery life may also be a limitation for those who rely heavily on wireless use without regular access to charging. Additionally, users who require open-source firmware customization through QMK, ZMK, or VIA will find the keyboard restrictive, as none of these are supported. It is also not designed for Mac users, making it a poor match for that ecosystem.
