Enjoy flexible Bluetooth wireless connectivity with your B&W Zeppelin Classic, Mini or Air speaker with the older 30 pin docking connector. Now using this receiver that inserts in the Aux Input socket, you can continue to enjoy your speaker dock and avoid obsolescence due to the later Apple iPhone/ipod connector not being compatible. Allows wireless connection to any Bluetooth enabled device such as iPhones, iPod Touch, iPads, Android phones, tablets, laptops and PCs.. 

Charging USB cable and instructions included.

Typical use of 10 hours between charges or continuous if connected to charger via USB.
