Glorious GMMK 3 HE Wireless 75%

Manufacturer: Glorious

The Glorious GMMK 3 HE Wireless 75% is a compact 75% gaming keyboard that combines wireless flexibility with a gasket-mounted build for a more cushioned typing feel. It supports three connection modes — USB, Bluetooth, and 2.4GHz wireless — making it adaptable to a range of setups without being tied to a single device. The keyboard ships in black or silver colorways and features an aluminum and plastic case with an aluminum plate, giving it a reasonably solid construction at this form factor. Adjustable feet allow for some tilt customization, and the detachable cable adds convenience for wired use.

On the technical side, the GMMK 3 HE is built around Glorious Fox HE Hall effect switches with a linear feel, 45 g actuation force, and 4 mm total travel distance. These switches are hot-swappable, and the board supports rapid trigger functionality alongside full N-key rollover at an 8000 Hz polling rate. Keycaps are PBT double-shot in an OEM profile with a standard ANSI layout, and a rotary dial is included for on-the-fly adjustments. RGB backlighting is present throughout, while media controls are accessible via the Fn key layer. The keyboard carries a 2-year warranty.

Pros
  • Supports three connection modes — USB, Bluetooth, and 2.4GHz wireless — offering flexible setup options
  • Gasket mount construction provides a softer, more cushioned typing experience compared to standard tray mounts
  • Hall effect switches are hot-swappable, allowing switch changes without soldering
  • Rapid trigger support enables more responsive input registration for fast-paced use
  • 8000 Hz polling rate delivers highly frequent input updates
  • Full N-key rollover ensures every simultaneous keypress is registered accurately
Cons
  • No support for QMK, ZMK, or VIA firmware, limiting custom remapping and macro options
  • Media controls are only accessible via the Fn key layer, with no dedicated media keys
  • No wrist rest is included in the package
  • Not designed for Mac use, restricting out-of-the-box compatibility
  • No analog input or dual actuation support, reducing versatility for users who rely on those features
Who is this for?

This keyboard is well-suited to users who want a compact 75% layout without giving up function row access, particularly those who work across multiple devices and value the flexibility of USB, Bluetooth, and 2.4GHz wireless connectivity. The gasket mount construction and hot-swappable Hall effect switches make it a strong fit for enthusiasts who care about typing feel and want the option to swap switches over time. The rapid trigger functionality and 8000 Hz polling rate also make it a reasonable choice for competitive or fast-paced gaming scenarios where input responsiveness matters.

Who is this NOT for?

Users who rely on QMK, ZMK, or VIA firmware for deep customization, complex macros, or open-source configuration will find this keyboard limiting, as none of these are supported. It is also a poor fit for Mac users, since the keyboard is not designed with macOS compatibility in mind. Additionally, those who prefer dedicated media keys or require analog input and dual actuation for specialized use cases will find the feature set insufficient for their needs.
