OnePlus Keyboard 81 Pro Review: The Dark-Horse Mechanical

OnePlus entered the mechanical keyboard market through a collaboration with Keychron, and the Keyboard 81 Pro wears that lineage openly. It is a 75 percent layout board with an aluminum chassis, a double-gasket mounted plate, hot-swappable switches, and open-source firmware support, connecting over USB-C or Bluetooth to Windows and macOS alike.

Why I Bought It

Curiosity, in part; a phone manufacturer shipping a serious mechanical keyboard warranted investigation. More practically, the specification list read like an enthusiast build: gasket mounting, an aluminum case, hot-swap sockets, and QMK-compatible firmware at a price below comparable boutique boards.

Real-World Use

Typing feel is where the double-gasket design shows its worth. Keystrokes land with a cushioned, slightly flexible bottom-out and a deep, muted sound profile that required no modification out of the box, which is uncommon even among enthusiast keyboards. The tactile switches are smooth and appropriately weighted for long writing sessions. The rounded keycap profile draws attention, and opinions in my household are divided; the look is distinctive, but the sculpt takes adjustment. Bluetooth pairing across multiple devices has been reliable, and the physical OS toggle is more convenient than software switching. Firmware customization through open-source tooling worked as advertised for remapping and macros.

The chassis deserves its own paragraph. The aluminum case gives the board a planted, dense presence on the desk, with no flex, rattle, or hollowness anywhere in the structure. Stabilized keys, the space bar and modifiers, arrived properly lubricated and free of the tick and rattle that budget boards accept. The hot-swap sockets invite experimentation; a partial switch change to test alternatives took minutes and no soldering. Battery life over Bluetooth has proven sufficient for weeks of intermittent wireless use, though the board spends most of its life wired, where latency concerns vanish entirely.

What I Dislike

The keycaps are the board’s most polarizing decision, and I remain unconverted; the rounded profile looks striking and types adequately, but replacement with a conventional profile improved my accuracy. The absence of a 2.4 GHz dongle is also a curious omission at this tier.

Why I Recommend It

The Keyboard 81 Pro delivers an enthusiast-grade typing experience without the group-buy waiting lists and assembly required by the hobby’s usual path. For a first serious mechanical keyboard, it is an unusually complete package.
