The Quad Lock AUX Bluetooth Adapter provides a compact way to add wireless audio to equipment fitted with a 3.5mm AUX socket. It can connect your Bluetooth earbuds or headphones to in-flight entertainment systems, gym equipment and older car stereos without relying on a wired listening connection.

Transmit mode sends sound from an AUX source to compatible Bluetooth headphones, while receive mode allows audio from a phone or other Bluetooth device to play through an AUX-equipped stereo. It supports connection with up to two headphones in transmit mode or two devices in receive mode, making it practical for travel and shared use.
