The Bluetooth convertible unit allows the user to use their Big Ear dual or triple transducers as a hard-wired set or a Bluetooth set with the simple transition of two metal prongs. Simply unplug the earpiece from the Bluetooth set when the battery dies and plug them into the wired chord and continue to listen to your music or communications while you charge the Bluetooth lanyard. The product displayed here is our triple transducer. The plug blocks out 32 dB of attenuation from the outside wind and road noise all while putting a 5.2 surround sound experience in your head. We designed the plug to come out of the face plate, so it has a dual purpose. You can bring it straight down to slide a motorcycle helmet on and go in the front or around the back of your neck. On our  Triple set, we use a passive noise canceling technology that is far superior to any active noise canceling technology ever created, as we are not creating sound to get rid of sound and the plugs are hearing protection first.
