Wired magnetic gaming keyboard

The Redragon Eisa HE K686 HE is a 98-key wired keyboard built for competitive players who want adjustable actuation without physical switch contact. Its UltraMag POM magnetic switches register every press through Hall-effect sensing, so inputs arrive exactly when intended during fast stop-and-shoot moments in titles such as Valorant or CS.

Single-knob lighting and media control

One aluminium knob on the top-right corner handles both RGB brightness and media playback, removing the need to memorise extra key combinations. Eighteen preset lighting modes and ten music-sync patterns run out of the box, while the web-based driver adds fully customisable 16.8 million colour effects without installing extra software.

Adjustable actuation from point-one

Software lets you set each key’s actuation point anywhere between 0.1 mm and 3.4 mm and save multiple profiles for different games. Rapid Trigger and 8,000 Hz hyper-polling cut redundant keystrokes during quick direction changes, but the board remains a pure wired USB device with no wireless or Bluetooth option.

Questions about this item

How do I install the Redragon Eisa HE K686 HE and what step is often missed?

Plug the USB cable into a free port; the keyboard is recognised instantly, then open the web-based driver in your browser to calibrate each UltraMag switch between .1 mm and 3.4 mm actuation — skipping calibration leaves every key at the factory default.

What maintenance or replacement will the keyboard need later?

The PBT round keycaps resist shine, but the linear UltraMag magnetic switches have no metal contacts to wear out, so only the keycaps or the detachable USB cable would ever need replacing.

What limit appears first during long gaming sessions?

The 8000 Hz wired polling rate keeps input latency at its floor, so the first bottleneck you hit will be the 3.4 mm maximum actuation travel if you prefer deeper presses for typing comfort.
