MH-102A4B Two-Wire Surveillance Kit: discreet inline-PTT audio for VX Series radios
Two-wire surveillance headset · Clear acoustic tube · Mushroom ear tip · Inline mic with PTT · Single-pin VX Series connector · Wears in either ear
The MH-102A4B is a two-wire surveillance-style headset that routes earpiece audio through a clear acoustic tube to a low-profile mushroom ear tip, with a separate wire carrying an inline microphone and push-to-talk button. The discreet routing keeps your audio private, making it well suited to security, event, and team-coordination work. It is built for VX Series two-way radios that use a single-pin accessory port.
Who it's for
Security teams, event staff, and crews who need to coordinate quietly and key up without reaching for the radio. If you run VX Series radios with a single-pin accessory port and want discreet, hands-on-task audio, this kit fits that workflow.
