Wireless ear-headphones with JBL's signature sound, up to eight hours of battery life, and a practical clip for the neck so they are held comfortably in place for long sessions. On the cable between the plugs there is a three-button remote control for controlling and making calls and music without receiving the phone. You switch easily from what is being played to the caller. The headphones are connected via Bluetooth to your smartphone.
Frequency range 20-20,000 Hz. Impedance 16 Ohm. Include USB charging cable and case.
