Keychron 81 Pro Keyboard Manual

Workspace Minimalism

With ever more devices, today's desks have become cluttered workspaces. This significantly inhibits creativity and productivity. The Keyboard 81 Pro addresses this problem with different orientations. Choose from the standard orientation or flip the keyboard upright from the user-facing side. This minimalist design inspires focus so you stay in your creative zone.

Touch Evolved

The mechanical keyboard utilizes Marble-mallow for the keycap material. Compared to ABS/PBT, the softer and more elastic properties ensure a superior tactile experience. Unlike other soft keycaps, such as silicone, Marble-mallow enjoys higher resistance to text fading and color degradation.

Powered by Co-Creation

We strongly believe in the power of community. We invited OnePlus fans to co-create the keyboard switches with our product manager. After multiple rounds of discussion, we decided on two great choices for our switches:

• Summer Breeze (linear switch, Klein Blue) delivers a smooth and consistent keystroke with fast yet near-silent actuation.
• Winter Bonfire (optimized tactile switch, OnePlus Red) features a tactile peak point of 0.5mm. Together with a stronger rebounding force, the larger tactile drop delivers a more solid typing experience.
