Compact 75% layout with volume knob

The Epomaker QK81 is an 81-key mechanical gaming keyboard built on a 75% form factor that frees desk space for mouse movement. A metal volume knob sits at the top right for quick audio control and can be remapped through software. Tri-mode connectivity covers 2.4 GHz wireless, Bluetooth and wired USB so the board works with a desktop, laptop or tablet without extra dongles.

Check switch preference and hot-swap compatibility

The unit ships with factory-lubed Wisteria linear switches that deliver a smooth keystroke without tactile bump or click. The PCB is hot-swappable, letting you pull switches and replace them with any 3-pin or 5-pin MX-style option without soldering. Verify that your preferred switch brand uses the standard MX stem and that you are comfortable with a linear feel before ordering.

Gasket mount, adjustable feet and stored receiver

A gasket-mounted structure adds cushion between plate and case for a softer typing sound and feel. Two embedded kickstand feet flip out to give a choice of typing angles. The 2.4 GHz USB receiver tucks into a dedicated slot on the underside so it stays with the keyboard during transport. Per-key RGB backlighting offers 16.8 million colour options configurable through VIA.

Questions about this item

What comes in the box with the QK81 and what must I buy separately?

The box contains the 81-key keyboard, a 2.4 GHz dongle that stores in a dedicated slot, a USB cable for wired use and charging, and a keycap puller. No extra accessories are required for tri-mode operation.

Which switch version should I choose for a linear feel?

The Wisteria switch listed is a pre-lubed linear option; the hot-swappable PCB lets you replace them with any 3-pin or 5-pin MX-style switch later if you prefer a different weight or sound.

How does the 16.8M RGB figure translate to daily use?

It means each key can display any of 16.8 million colours, letting you set per-key lighting, reactive effects, or static colours through VIA software to match your setup or highlight gaming layers.
