EARPHONE / MICROPHONE ASSEMBLIES

The EM-OTS2 earphone and microphone assemblies are designed to connect hard-wire or through-water communications to a helmet or full face mask (FFM). The latest generation features an updated design focused on increased durability and reliability in high-use diving environments.

Improvements include a new PTT circuit, Kevlar reinforcement in the Hi-Use cable, enhanced earphone cable length and strength, and the addition of the ME-150 microphone. Due to the wide variety of FFM styles and applications, multiple configurations are available. Custom E/M assemblies can be built on request, while standard configurations offer easier availability.
