twelve south 12-2259 AirFly SE Bluetooth Wireless Audio Transmitter for AirPods /Wireless Headphones, 20+Hrs Playtime, Use with any 3.5 mm Audio Jack on Airplanes, Gym Equipment or iPad/Tablets

AirFly bluetooth audio transmitter lets you stream wireless audio to your AirPods or other bluetooth headphones from devices that do not have built-in Bluetooth, such as in-flight entertainment systems on airplanes, gym equipment in fitness centers and anywhere else with only wired headphone jacks. Simply plug AirFly into the headphone jack on an airplane seat or treadmill at the gym to listen movies or shows with your AirPods. It’s that easy. AirFly stays charged for over 20 hours (much longer than the competition so you won't run out of battery in the middle of a long flight) and includes a USB charging cable and travel pouch. AirFly SE uses technology for high-fidelity, lag-free audio.
