EPC is now shipping the Micro Sound 1A tubeless receive-only earpiece for any remote speaker-mic with a 3.5mm audio jack. It uses a micro-speaker and eliminates the transducer and acoustic tube. Speaker audio is clearer over time as compared to a tube that accumulates dirt and moisture.
The EP-MS1A-B includes a black Fin Ultra Ambi that can be worn on either ear. It is also available with a clear Fin Ultra EP-MS1A-C. The Fin Ultra is more comfortable than standard ear tips and allows for better situational awareness.
The Micro Sound 1A has a 12 month warranty.
