1-Wire Surveillance Earpiece with Clear Acoustic Tube, In-Line Mic & PTT

The Motorola PMLN7158A 1-Wire Surveillance Earpiece provides discreet, reliable communication for professionals who need to receive and transmit radio calls without drawing unnecessary attention. Its clear acoustic tube routes incoming audio directly to the ear, helping conversations remain private in busy or public environments.

This single-wire surveillance kit combines the earpiece, in-line microphone, and push-to-talk button into one streamlined cable. The simplified design reduces wire clutter while allowing users to communicate without repeatedly removing their radio from a belt, pocket, or carrying case.

Designed for comfortable extended wear, the PMLN7158A is an excellent choice for security, hospitality, retail, event management, education, and other operations that require discreet hands-free communication. Its professional black finish and low-profile clear acoustic tube help the accessory blend naturally with work attire.
