This earpiece is the perfect solution to communications problems found in casinos, hotels and restaurants. The Messenger uses a coiled accoustic tube, the most comfortabe earpiece design. Custom earpiece focuses on comfort and durability in our designs, that is why a coiled wire plugs into your radio and runs up to a small, discreet, microphone and push-to-talk (PTT) unit. The coiled wire provides a shock absorber, so if you drop the radio, neither the radio nor the earpiece will be damaged by the fall! The clear coiled tube provides great discretion and comfort. It also adds to durability, the top quality wire is not twisted when you turn your head. We are so confident these will last you, that we will replace them for one year, no questions asked - and even pay the shipping both directions!
