The Sport Wireless + Bluetooth Headset from Jabra is designed for playing back music, taking calls, and listening to FM radio stations while working out. It has an integrated mic for answering calls and an FM radio that allows you to listen to music without bringing a portable audio device with you while working out. The headset's built-in rechargeable battery provides up to 8 hours of talk time and up to 120 hours of standby. A 3-month subscription to the digital personal trainer Endomondo Premium is included along with a USB cable, carry bag, and three pairs of ear gels to provide you with the most comfortable fit.
