Harman/Kardon BT

BT, Bluetooth Harman Kardon® BT headphones feature an exclusive acoustic system that integrates superb mechanical design, materials and electronics. User-exchangeable bows, self-adjusting housings, soft leather cups and slow-retention ear-cup foam ensure a comfortable fit and an optimal acoustic seal on the ear. The lightweight, comfortable headphones employ AAC (Advanced Audio Coding) and apt-X® coding for the highest-quality wireless audio, and incorporate a built-in microphone and playback buttons. The USB-rechargeable BT headphones have a battery that lasts up to 40 hours. And unlike competitive Bluetooth® headphones, the headphones will still work when connected by the supplied bypass cable to a playback device, even when the headphones’ battery dies.
