Vertex Standard MH-450S Medium-Duty Remote Speaker Microphone with 3.5mm Earpiece Jack

The Vertex Standard MH-450S is a medium-duty remote speaker microphone designed for convenient, hands-accessible communication with compatible two-way radios. It allows users to hear and transmit radio traffic without repeatedly removing the radio from a belt or carrying case.

An integrated push-to-talk button provides quick transmission, while the built-in speaker delivers incoming audio near the user’s shoulder. The included lapel clip keeps the microphone securely positioned during everyday work activities.

A built-in 3.5mm audio jack supports a compatible receive-only earpiece for more discreet listening in noisy, public or customer-facing environments.

Compatibility

The MH-450S is designed for select Vertex Standard two-way radios using the appropriate accessory connection.

Radio compatibility depends on the model and connector configuration. Verify your radio’s complete model number and accessory connector before ordering.

3.5mm Earpiece Connection

The integrated 3.5mm jack allows a compatible receive-only earpiece to be connected directly to the speaker microphone. This provides more private incoming audio while transmissions continue through the microphone’s push-to-talk button.

The connected earpiece must have the appropriate 3.5mm plug and electrical configuration.
