Ear Hook - 1 Wire - Both Lines out of Bottom of PTT

This is a one wire ear hook earpiece with both lines routed out of the bottom of the push-to-talk module.

One wire means the speaker and the microphone share a single cable to the PTT, so there is one line to manage rather than two. The ear hook holds the earpiece in place over the ear instead of relying on a friction fit inside it, which suits a user who is moving rather than seated.

Routing both lines out of the bottom of the PTT is the detail buyers get wrong. It decides how the assembly hangs once it is clipped on, and an earpiece built the other way will wear differently on the same person.

⚠️ Earpiece connectors differ between radio series even where the earpiece looks identical. Call CMI at (310) 753-0991 and we will identify the correct connection for the radios you already own.
