Cobra’s line of 2.1 Bluetooth wireless headsets for hands-free phone operation comes with noise cancellation technology and Voice Over Internet Protocol, meaning calls can be made through Internet connection. The headsets can be worn on either ear and store up to eight paired devices. Features include a one-touch on and off button and volume controls. The battery has time for 5 hours of talk, 5 hours of music streaming and 300 hours of standby. The Sport Headset, also new, is smaller than the 2.1 model, its earpiece sits flush against the ear, and it offers 7 hours of talk time and 100 hours of standby time. Both headsets come with USB and vehicle chargers.
