AirFly for Wireless Headphones. Use your AirPods or wireless headphones with any wired headphone jack.
For those moments you need to use your cordless, wireless headphones or earphones with a source that does not emit wireless sounds. E.g. Wired player. Airplane entertainment systems.
Basically a bluetooth transmitter ? 🙂
Accordingly to the web site:
• Allows wireless headphones to connect to wired headphone jacks
• Use to pair AirPods with airline in-flight entertainment systems
