Details
The integral inductive loop is part of a communication system and is used with an inductive in-ear receiver.
The inductive loop consists of a reception unit， a PTT button (PTT: push to talk)， an inductive coil and an integral omni-directional microphone. Covert communication between 2 way radio and wireless earpiece can be carried out via this loop.
Wireless PTT uses water proof high quality material. It is typically used for 2-way radio PTT concealed remote control. It looks like car remote control and is convenient to applications under specific circumstance.
