🎧 Overview & Compatibility

This earpiece is purpose-built to work with Radioworx’s 4G LTE PoC radios—specifically the K300 and the Radioworx G7. It connects via a USB Type‑C style plug, matching the accessory port on these radios. Ideal for usage, in security, Whilst driving, cycling etc.



Design & Build

Over‑Ear Hook Style: Features a flexible loop that comfortably hooks over the ear. The speaker sits just outside the ear canal, resting on the ear’s outer ridge—balancing comfort and stability over extended wear.

Durable Construction: Made with sturdy yet supple materials: non‑abrasive PU or TPE cable, flexible strain reliefs, and a reinforced plug housing to resist wear and accidental pulls.

Cable and Plug Interface: A short lead connects the over‑ear module to a rigid USB‑C plug assembly designed to mate snugly with the radio’s accessory port. Overall length is practical—not too bulky or restricting.

PTT/Mic Integration: Many variants combine a push‑to‑talk button and mic inline in the cable (some models include dual PTT—roof‑square plus rounded button) for hands‑free transmission control in noisy environments .


Acoustic Performance

Receive‑With Mic:

Audio Clarity: The earpiece delivers clear signals with moderate passive noise isolation. Over‑ear placement prevents occlusion and allows ambient awareness—useful in operational settings where hearing surroundings matters



Comfort & Ergonomics

Lightweight Hook Design: The open‑hook earloop reduces pressure and heat—suitable for extended shifts.

Balance of Isolation and Awareness: It’s not fully sealed like an in‑ear earbud, allowing situational sound alongside radio comms.

Language & Fit: Intended for either ear; adaptable ear‑loop shape fits a variety of ear sizes.
