CavCom‘s Talk Through Your Ears® and RadioGear® earpieces may connect to other devices that have a 3.5mm or 2.5mm audio jack.  The Talk Through Your Ears® function of the earset, however, is only achieved when used with the Talk Through Your Ears® control unit and a 2-way radio. A better option is CavCom‘s CellEarz™ earset or other accessories which are designed specifically for use with a personal phone or music device.
