Wireless mechanical keyboard

The Redragon K688SP-RGB-PRO is a wireless mechanical keyboard built for users who switch between multiple devices. It connects via Bluetooth 5.0, 2.4 GHz wireless, or USB-C wired modes. The board supports simultaneous pairing with up to five devices for quick switching.

Gasket structure with hot-swappable cream switches

A gasket mount and five layers of silencing material create a soft, elastic typing feel with reduced cavity noise. The PCB accepts both 3-pin and 5-pin switches for full customisation. Pre-lubed linear cream switches deliver a smooth, creamy sound profile out of the box.

Side-printed PBT keycaps with RGB backlighting

Translucent side-printed keycaps allow vibrant RGB lighting to shine through for dynamic effects. The keycaps are made from durable PBT material. A multi-function knob provides quick access to media or system controls.

Questions about this item

Will the USB-C wired mode work with a desktop that only has older USB-A ports?

Yes, the keyboard connects through its USB-C port and a USB-C to USB-A cable satisfies the single USB port requirement.

How can I confirm the gasket structure and pre-lubed cream switches are delivering the intended softer feel and creamy sound?

Press several keys and listen for a deep, muted thock without hollow ping; the five-layer silencing and single-key PCB slotting should make each keystroke feel cushioned and consistent.

Does the box include the 2.4 GHz receiver and a USB-C cable, or must I buy them separately?

The package supplies the 2.4 GHz dongle and a USB-C cable for wired use and charging; no extra purchase is needed for either connection method.
