    This is my favorite accessory that I use with my EVX-531 radio. The audio is loud and clear and it is extremely lightweight and dependable.

    I use this speaker mic for my VX-231 radio. It has been great for our applications. This is the lowest price I have seen on this product anywhere online.

    Great Shoulder Microphone

    Posted by Unknown on 6th Feb 2014

    Been shopping around and everything was so expensive. Found this at a way better price than everywhere else. Works great too! Only took a couple days to get it to me too. Nice!

    My department just ordered these for our portable and mobile radios. We are excited to try them out. Two way direct was great to work with - they helped us find the one that would work best for us (price and quality wise).
