AirFly is a wireless headphone adapter that lets you use your favorite wireless headphones or earbuds in places that only have a headphone jack – like airplanes and treadmills. Plug this tiny transmitter into a headphone jack to listen to in-flight movies or the TVs at the gym. AirFly Pro lets two people listen to the same soundtrack, podcast or music with their favorite noise-cancelling headphones or AirPods. Connect two pair of headphones to share music, movies and more. New 16+ hour battery lasts as long as your longest coast-to-coast flight. Use AirFly Pro as an AUX IN adapter for your car, boat or non-Bluetooth speaker.
