The Redragon K689 PRO is a full-size, 108-key mechanical keyboard that connects by cable, Bluetooth or a 2.4GHz wireless receiver. It is built around a gasket mount and sound-dampening foam, aiming for a softer, quieter typing feel than a traditional rigid board. It also has RGB lighting and software for custom effects and macros.
What a gasket mount changes
In a traditional keyboard the plate and circuit board are screwed rigidly to the case. A gasket design instead holds the internal assembly between soft pads, so it can flex slightly under each keypress. Redragon says its precision-locked covers and gaskets give even feedback and reduce harsh, rigid noise, for a cushioned and softer typing feel. How pronounced that is varies from person to person, but the general idea is a less jarring bottom-out.
Three layers of dampening
Redragon lists several foam layers: 3.5mm PO foam, IXPE switch foam and bottom socket foam, along with the silicone gasket. Foam inside a keyboard typically absorbs the hollow, echoing sound a plastic case can make. Redragon says the result is a cleaner, lower-pitched typing sound.
Linear switches you can swap
The board uses Redragon's custom Mint Mambo linear switches, which the brand describes as thick-lubed with cushioned, smooth travel. Linear switches go straight down with no tactile bump or click, which many people prefer for fast, quiet typing and gaming.
The switch sockets are hot-swappable, so switches pull out and replace without soldering. Redragon says the upgraded socket accepts nearly all 3-pin and 5-pin switches. That lets you try different switch types over time, though you should confirm compatibility for any switch you buy.
Three ways to connect
The tri-mode setup covers USB-C wired, Bluetooth (3.0 and 5.0) and 2.4GHz wireless. A wired connection is generally the most dependable for gaming, while Bluetooth lets one keyboard serve a laptop or tablet without a receiver. The 2.4GHz mode typically offers low latency without a cable.
Layout, keycaps and software
The 108-key layout includes a number pad plus four extra hotkeys. The round PBT keycaps are mixed in three colours, and PBT plastic typically resists shine and wear better than ABS. Two-stage adjustable feet change the typing angle. The weight is listed as 1.9 lb (about 0.9 kg).
Redragon offers software, found on its own site, for designing lighting modes and effects and for setting macros with custom keybindings or shortcuts.
Who it suits
It suits people who want a full-size board with a number pad, who like a cushioned linear feel, and who may want to experiment with switches later. It also suits those who move between a desktop, laptop and tablet and want wireless options.
What to check before you buy
- Size: a full-size board with a number pad needs more desk width than a compact one. Measure your space.
- Software support: check that the Redragon software runs on your operating system.
- Switch feel: linear switches have no tactile bump. If you prefer a clicky or tactile feel, you would need to swap them.
- Replacement switches: confirm the pin count and fit before buying.
- Charging: wireless use relies on the built-in battery, so plan to charge it by USB-C.
- Layout: check that the key layout matches your language and habits.
