Twelve South Airfly Pro

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. AirFly Pro lets two people listen to the same movie, podcast, or music with their favourite wireless headphones or earbuds. AirFly Pro also adds the ability to stream music from your iPhone to an AUX IN in a car or speaker.
