Designed for use with a Vertex standard transceiver, the MH-45B4B noise-canceling speaker microphone is a heavy-duty accessory that connects via a 3.55mm earphone jack and clips securely to your uniform, enabling faster communication and less chance for dropping a radio that’s clipped to your belt.

Built to be intrinsically safe for even potentially combustible environments, this unit weighs just 8 ounces and features a volume toggle switch that greatly reduces the speaker’s volume levels without turning it off completely. This enables the user to make sure that the communications coming in from teammates can be heard even in loud, chaotic environments.


Works with most Vertex handheld devices, including:

  • VX-160
  • VX-230
  • VX-350
  • VX-410
  • VX-420
  • VX-420A
  • VX-261
  • VX-264

NOTE: The MB-45B4B will work with the Vertex EVX-534 radio. However, the microphone is not IP rated like the radio, so it is recommended that you use the MH-66A4B waterproof speaker microphone instead.
