About Zifriend RX75

The Zifriend RX75 is a standout contender in the budget-to-midrange mechanical keyboard market, striking a precise balance between enthusiast-grade features and approachable pricing. Utilizing the popular 75% layout (80 keys), it retains the essential function row and arrow keys while significantly reducing the desk footprint compared to full-sized boards.

The core of the RX75’s appeal is its gasket-mount structure. Unlike traditional tray-mount designs, the gasket system uses internal dampening layers (often five layers of foam) to provide a softer, more cushioned typing feel. This design effectively eliminates metallic "ping" and produces the "thocky" or "creamy" sound profile highly sought after by keyboard hobbyists.

Hot-Swappable PCB: The board features a 5-pin hot-swap socket, allowing you to easily swap out the stock switches (often Outemu or Zifriend's custom TNT switches) for any 3-pin or 5-pin alternatives without soldering.

Multifunction Knob: A tactile metal knob in the top-right corner allows for quick volume adjustments and media control, adding a layer of convenience for both gaming and productivity.

PBT Keycaps: It comes equipped with double-shot PBT keycaps, which are far more durable than standard ABS plastic. These resist the "shiny" texture that develops over time and ensure the legends (letters) never fade.

Dynamic RGB: The RX75 features south-facing RGB backlighting, which offers better compatibility with different keycap profiles (like Cherry) and provides a more vibrant glow toward the user.

While the RX75 is celebrated for its stable wired Type-C connection, the "Pro" variant often includes Tri-mode connectivity (Wired, 2.4GHz Wireless, and Bluetooth) powered by a massive 4000mAh battery.

Whether you're a gamer needing N-key rollover or a writer looking for a refined tactile experience, the Zifriend RX75 serves as an excellent entry point into the world of custom mechanical keyboards.t.
