The Speed Charge Battery allows for one hour of playback with just five minutes of charging time, and plays for over 11 hours when fully charged. The headphones feature an embedded RunSafe LED feature with three flashing modes for increased visibility and safety in low-light conditions.

Four simple buttons enable athletes to control their music, take phone calls, control the RunSafe LED and trigger Siri and Google Now.
