Manufacturer description

The YUNZII B75 PRO is a 75% wireless mechanical keyboard built for sound and feel. It has 82 keys, so you keep the function row and arrow keys while freeing desk space for your mouse. The keyboard uses a gasket-mount design with five layers of padding, precision-tuned stabilizers, double-shot keycaps, and pre-lubed Cocoa Cream V2 linear switches. Together they give each keystroke a soft, creamy sound. If you want to change the feel later, the hot-swap PCB takes both 3-pin and 5-pin switches, and you don't need to solder. You can connect over Bluetooth, 2.4GHz wireless, or a wired USB-C…

Frequently Asked Questions

Does the YUNZII B75 PRO work with a Mac?

Yes. The listing says the B75 PRO works with Windows and macOS over Bluetooth, 2.4GHz wireless, or wired USB-C. The programming software for key remapping, macros, and RGB is described for Windows only.

How long does the battery last on a charge?

The B75 PRO has a built-in 4000mAh battery. The listing doesn't give a battery life in hours. Actual runtime depends on how bright the RGB is and which wireless mode you use, so check the manufacturer's documentation for rated figures.

Can I swap the switches on the B75 PRO?

Yes. Every key sits on a hot-swap socket, and the PCB takes both 3-pin and 5-pin mechanical switches. You can pull out the included Cocoa Cream V2 switches and put in others without soldering.

What does the knob on the YUNZII B75 PRO do?

Turn the knob to change the volume or cycle through RGB backlight effects. Press and hold it to switch between gaming mode and office mode.

Is the B75 PRO a full-size or TKL keyboard?
