The Marmitek BoomBoom 50 plugs into the 3.5 mm audio output of a TV, hi-fi system, or any sound source and transmits audio wirelessly via Bluetooth to paired headphones or a Bluetooth audio receiver. This allows silent listening at full volume without disturbing others in the room.

USB-powered (5V), it connects directly to a TV USB port or a USB mains adapter. Auto-pairing means the device reconnects to your headphones automatically each time it is switched on.
