Listen to music on your smartphone or mp3 player while remaining vigilante and on-top of your job with this Two-Way Radio Headset with Dual Plug Ins! Connect your two-way radio with the 2-pin plug and your smartphone or music player with the 3.5mm plug to simultaneously listen to both at the same time!

Don't worry about people finding out your music playlist. When someone speaks on your radio line, the music is automatically muted so the radio line takes priority and when the communications end, the music also automatically resumes. When you speak, you can still hear the music but nobody else can and the other person on the line will still be able to hear you clearly.

Works well with discreet radio communications without the music interfering your work. Switch button also allows you to play and pause music at whim so you can be ready to adjust to your work pace anytime. You can even hide the button under your clothes so you can control the settings discreetly. Also works with Google Assistant.
