Compact 75% Gasket Keyboard

The YUNZII B75 PRO is a 75 percent layout mechanical keyboard with 82 keys and a multimedia control knob. It targets users who want a smaller footprint than a full-size board while keeping dedicated function and arrow keys. The gasket-mount design with five layers of padding aims to deliver a creamy typing sound and solid feel for both gaming and office work.

Tri-Mode Wireless with Large Battery

Connectivity options include Bluetooth, 2.4 GHz wireless and a wired USB connection. A built-in 4000 mAh battery provides extended wireless runtime for long work sessions or gaming. The board uses pre-lubricated Cocoa Cream V2 linear switches with a 50±10 gf actuation force, 2.0 mm pre-travel and 3.30 mm total travel for a smooth, quiet keystroke.

Upgrade from Membrane or Non-Hotswap Boards

This keyboard suits buyers moving from membrane keyboards or fixed-switch models who want hot-swappable sockets, gasket mounting and a programmable knob. It is not for users who require a dedicated numpad, a larger 96% or full-size layout, or an integrated display module. The 75% form factor saves desk space while retaining essential keys.

Questions about this item

How do I install the 2.4 GHz wireless dongle and what step do people often miss?

Plug the USB receiver into a free port, turn the keyboard's power switch on, then press the pairing key combination shown in the quick guide; the step most users skip is holding the Fn plus the designated key until the indicator flashes.

What maintenance will the Cocoa Cream V2 switches need over time?

The switches are factory pre‑lubed and rated for 50 million keystrokes; no re‑lubrication is required, but you can hot‑swap individual switches if a key feels different after heavy use.

What limit appears first during long gaming sessions?

The 4000 mAh battery will run down before the switches reach their 50 million‑press rating, so plan to recharge via USB‑C after extended wireless play.
