Frequently Asked Questions

Is the Redragon K668 hot-swappable?

Yes. It uses upgraded hot-swap sockets, so you can pull the stock Dragon Chant linear switches and install different switches without soldering.

What switches does the K668 come with?

It ships with Redragon's custom Dragon Chant linear switches, thick-lubed from the factory for smooth travel. Only the linear variant is listed for this model.

Is this keyboard quiet enough for an office or shared room?

It is built for muted sound: a gasket form factor plus sound-absorbing foam damps the hollow resonance typical of plate-mount boards. Linear switches are also non-clicky, though they are not silent.

Does it work without installing software?

Yes. All 19 RGB presets, brightness, and flow speed adjust from the keyboard itself. Redragon's optional software from redragonshop adds custom effects and macro keybindings.

How many keys can I press at once for gaming?

104 of the keys are anti-ghosting, so simultaneous presses register correctly during gameplay. The board is a full 108-key layout including 4 extra shortcut keys.

Is the Redragon K668 wired or wireless?

Wired. It connects by cable only, with no Bluetooth or 2.4GHz receiver listed, so there is no battery to charge.
