The compact black unit pairs quickly and includes volume controls on the device.

Build integration

Plug the transmitter into a standard 3.5 mm auxiliary port on an airplane seat, treadmill or tablet and pair it with your Bluetooth headphones. No extra cables or adapters are required and the USB-C charging cable allows the unit to operate while charging. The 25 in form factor slips into a pocket or bag for easy transport.

Capacity and headroom

The internal battery delivers over 20 hours of continuous playback on a single charge, covering long-haul flights or multiple workout sessions.
