The ZIFRIEND RX75 is a feature-rich mechanical keyboard designed for gaming and productivity users who want flexibility and customization. It supports tri-mode connectivity (typically Bluetooth, 2.4GHz wireless, and USB wired), powered by a high-capacity 4000mAh battery for extended wireless use.

Its hot-swappable switch sockets allow users to replace mechanical switches without soldering, while durable PBT keycaps provide long-lasting texture and resistance to wear. The gasket-mounted structure improves typing comfort by reducing vibration and creating a softer keystroke feel. RGB backlighting adds full customization, and the integrated knob provides quick control for volume or other functions depending on configuration.
