The Yaesu SSM-512B is a professional ergonomic earpiece microphone engineered to deliver crisp, discreet, and reliable audio communication for handheld two-way radios and transceivers. Built into its microphone module is an integrated mode switch that allows operators to easily toggle between manual push-to-talk (PTT) transmission and voice-activated (VOX) hands-free operation without needing to adjust the radio body.
Its ergonomic ear-hook fits comfortably and securely over the contour of the ear, preventing slippage during sudden movements or prolonged shifts. The inline microphone unit features a sturdy 360-degree rotating metal clip designed to anchor firmly to shirts, lapels, or tactical vests, keeping the cable tidy and ensuring consistent, close-proximity voice pickup even in active work environments.

Frequently Asked Questions
How does the VOX / PTT switch function?
The switch on the microphone capsule allows you to select VOX mode—which triggers automatic transmission as soon as your radio detects your voice—or standard PTT mode, which only transmits while holding down the tactile button.
Is this earpiece comfortable for long work shifts?
Yes. Because the contoured hook sits over the outer ear rather than wedging deeply into the ear canal, it eliminates the ear fatigue and discomfort common with standard in-ear earbuds.
