Ultrasone SIRIUS Bluetooth Adapter for Performance Series Headphone

Instead of expanding the qualities of the Performance series in a new model with Bluetooth technology, ULTRASONE have developed a module that turns every headphone in the Performance series into a Bluetooth headset. You simply disconnect the cable from your performance - and plug the SIRIUS Bluetooth module in its place. Enjoy your music via Bluetooth aptX® technology with complete freedom of movement.
