Compact gasket design

The Redragon K673 MAX is a 75% layout gaming keyboard with 81 keys and a gasket-mounted structure that uses precision-locked covers for even feedback and reduced rigid noise. Its compact form factor suits setups where desk space is limited while retaining a dedicated control knob for quick media and backlight adjustments.

Suits users who want quiet wireless flexibility

This keyboard targets typists and gamers who value dampened acoustics from the five-layer noise dampening system and the versatility of USB-C wired, 2.4 GHz wireless, and Bluetooth connectivity. Buyers who require a full-size layout with a separate number pad or dedicated macro keys should look at larger form factors.

Hot-swap socket compatibility

The board features a hot-swap socket that accepts nearly all 3-pin and 5-pin mechanical switches, letting you change the feel without soldering. If you prefer a fixed, non-hot-swap PCB or need a specific switch type not supported by the socket, this model will not meet that requirement.

Questions about this item

What comes in the box with the Redragon K673 MAX and do I need to buy switches or keycaps separately?

The keyboard ships fully assembled with 81 keys, PBT keycaps and pre-lubed Custom Mint Mambo linear switches installed. The hot-swap sockets accept most 3-pin and 5-pin switches if you want to change them later, but no extra purchase is required to start typing.

Which version of the K673 MAX should I choose for the gasket mount and 5-layer noise dampening?

The single model described includes the gasket structure, five dampening layers (3.5 mm PO foam, IXPE switch foam, PET sound pad, bottom socket foam, silicone bottom pad plus silicone gasket) and the Custom Mint Mambo switches — there are no alternative versions listed.

How does the 75 % layout with 81 keys and the dedicated knob feel in daily use compared to a full-size board?

The 75 % form factor keeps the function row, arrows and navigation cluster while saving desk width; the single knob controls backlight brightness and media volume or play/pause without extra key combinations.
