Full-size wired mechanical keyboard

The Redragon K668 is a full-size wired mechanical keyboard with a 108-key layout and a USB-C connection. It ships with linear Red switches that are hot-swappable, plus sound-absorbing foam for a quieter typing experience. RGB backlighting offers up to 19 preset modes with adjustable brightness and speed, including a music-sync option. Two sets of mixed-colour keycaps and a keycap puller are included for easy customisation.

Gamers and typists who want hot-swap flexibility

This keyboard suits users who want to experiment with different 3-pin or 5-pin switches without soldering, and who appreciate dedicated media shortcuts that can be remapped via software. The linear Red switches keep noise low for shared spaces, while full 104-key anti-ghosting handles rapid multi-key input. Buyers who need a detachable wrist rest or wireless connectivity should look at other models, as this unit has neither.

Check your desk space and USB-C port

Verify that you have room for a keyboard measuring 17.3 by 4.7 inches and a free USB-C port on your PC for the wired connection. The package includes a USB-C cable, a switch puller, four spare Red switches and a user manual. No additional drivers are required for basic operation, though the companion software unlocks macro programming and deeper lighting control.

Questions about this item

Does the USB-C connection require a free USB-C port on my PC, or can I use an adapter?

The keyboard connects via a detachable USB-C cable, so you need either a native USB-C port or a USB-C-to-USB-A adapter on the computer.

Will the hot-swappable sockets accept the Cherry MX switches I already own?

Yes, the upgraded sockets support almost any 3-pin or 5-pin mechanical switch, so existing Cherry MX switches will fit without soldering.

How can I confirm the RGB lighting is responding to music after I enable the sync mode?

Play audio on the PC; the 19 preset modes include a music-sync option that makes the backlight pulse in time with the desktop sound output.
