Compact 75% Layout for Gamers

The YUNZII RT75 PRO is a 75 percent mechanical keyboard with 81 keys plus a knob, built for players who want a smaller footprint without losing the function row or navigation cluster. Hall Effect magnetic switches replace traditional contacts for adjustable actuation and rapid trigger response. Triple-mode connectivity covers USB-C wired, 2.4 GHz wireless and Bluetooth for desktop and laptop setups.

Hall Effect Switches and Multi-Layer Damping

Outemu Magnetic Red switches use Hall Effect sensing for contactless keystrokes, while a five-layer sound-damping stack and top-mounted structure reduce ping and hollow resonance. Double-shot PBT&PC Cherry-profile keycaps resist shine and keep legends clear. South-facing RGB LEDs shine through the keycaps without switch-shadow interference. The board is fully hot-swappable for switch experimentation.

8000 mAh Battery and 8K Polling

An 8000 mAh lithium-ion cell powers the keyboard through extended wireless sessions; Bluetooth runs at 125 Hz polling while wired and 2.4 GHz modes reach 8K Hz for 0.1 ms and 1 ms response respectively. The ABS case measures 332 by 137 by 38 mm and weighs 1129 g, staying stable on the desk during intense play. Web-based driver software configures TGL, SOCD, DKS and MT functions on Windows and macOS.
