Earphone/Microphone Assemblies are designed to allow the user to connect either Hard-wire or Through-water communications to a helmet or full face mask (FFM). Due to the many styles of ffm on the market, we offer a wide variety. The configurations can be endless depending on the application. The listed configurations are the most commonly used. Custom Earphone/Microphone (E/M) Assemblies can be manufactured upon request. However, off-the-shelf assemblies will be more readily available.

The OTS Guardian/Spectrum Ear‑Mic Assembly is a high‑performance communication interface designed for full‑face masks (FFM) and helmet systems like the Guardian and Spectrum series. Featuring dual 150‑ohm earphones, a top‑tier salt‑water‑resistant microphone (e.g., ME‑150 “Hot Mic”), and a rugged EP4 connector interface, this assembly is ideal for commercial, search & rescue, public‑safety, and technical diving operations. Whether configured for hard‑wire or through‑water comms, it delivers clarity, durability, and integration with professional diver systems.
