The black One-Wire Monitoring Surveillance Kit with Acoustic-Tube Earpiece and PTT Microphone from Otto Engineering is designed for security work, crowd control, and other applications where discreet two-way communication is desired. The kit offers clear and intelligible sound and an in-line push-to-talk microphone and features an HX connector for use with the Hytera PD606 and PD602 two-way radio systems.
The single-wire design uses a silicon eartip and can be worn on either the left or right ear, while the kit's clear acoustic tube helps to reduce background sound and can be quickly disconnected, making the unit easy to share between shifts. The rugged build is engineered to withstand the rigors of everyday use and features a durable clip for secure clothing attachment.
