Vertex MH-100 Earpiece: discreet, receive-only audio for your remote speaker mic
Receive-only earpiece · 3.5 mm audio jack · Connects to Vertex standard RSM · Listed for 8 Vertex radios · Vertex brand
The MH-100 is a receive-only earpiece that plugs into your Vertex standard remote speaker microphone (RSM) through a 3.5 mm audio jack. It directs incoming audio straight to your ear instead of broadcasting it from the RSM speaker, so you can monitor traffic discreetly, hear clearly in high-noise environments, and keep conversations private. You keep transmitting through your RSM as usual.
Who it's for
It is ideal for anyone who needs to monitor radio traffic without broadcasting audio out loud: security teams, event and venue staff, retail and warehouse crews, and anyone working in loud surroundings or where keeping incoming audio private matters.
Key features
- Receive-only audio: routes incoming audio to your ear only, so traffic stays private and discreet.
- Clear in high noise: directs audio to your ear instead of the open speaker, making it easier to hear in loud environments.
- Simple 3.5 mm connection: plugs into the audio jack on your Vertex standard RSM and reroutes audio instantly.
- Keeps your existing setup: works alongside your remote speaker mic, which you still use to transmit.
- Broad Vertex compatibility: listed for eight Vertex two-way radio models when paired with a standard RSM.
