TWELVE SOUTH AIRFLY PRO

Enjoy wireless audio with this Twelve South AirFly Pro Bluetooth transmitter. AirFly Pro is a wireless adapter that lets you use your wireless headphones or earbuds in places that only have a headphone jack, like airplanes and treadmills. Plug this tiny transmitter into the headphone jack to listen to in-flight movies or TVs at the gym. The 3.5mm jack pin connects to an aux input for simple streaming, while the built-in battery delivers reliable power for up to 16 hours of use per charge.
