75% mechanical keyboard with knob

YUNZII B75 PRO

The B75 PRO keeps the everyday controls close: a function row, dedicated arrows and a rotary knob in a 75% layout. Turn the knob for volume or switch it to lighting control. A gasket-mounted build, five damping layers and hot-swap sockets give this wireless keyboard plenty of scope for small personal adjustments.

A quick turn for volume

The knob sits at the top right, within easy reach of the main keys. In multimedia mode, turning it changes volume and pressing it mutes or unmutes. Switch to RGB mode to adjust brightness and cycle the lighting with the same control.

The layers below the keycaps

A gasket structure supports the typing assembly, with five damping layers beneath the keys. The construction diagram includes a PC plate, foam, PET and silicone components. Pre-lubricated stabilisers support the larger keys, while the double-shot PBT keycaps use a sculpted Cherry profile.

Change the feel, keep the layout

Full-key hot-swap sockets let you replace compatible 3-pin or 5-pin mechanical switches without soldering. The 75% arrangement keeps the function row and arrows together with a short navigation column. You can experiment with the switches while leaving those familiar positions in place.

Choose a connection, then set your keys

Use Bluetooth, the 2.4 GHz receiver or USB-C to connect. A 4000 mAh battery handles wireless use, with a keyboard shortcut to check its level. The Windows customisation software covers key assignments, macros and RGB; using the keyboard on macOS is separate from software support.

Frequently asked questions

Can I use it with a Mac?

Yes, for everyday keyboard use. The customisation software is Windows only, so its key-remapping, macro and lighting tools are not confirmed for macOS.

Does this B75 PRO support QMK/VIA?

QMK/VIA support is unverified for this version. Its documented customisation software is a Windows-only driver, so do not choose it on the assumption that it supports QMK/VIA.

Which switches are included?

Check the selected product option for the fitted switches. You can replace them later with compatible 3-pin or 5-pin mechanical switches using the hot-swap sockets.
