The wireless adapter can convert any audio signal from a 3.5mm device or a dual 3.5mm jack (commonly found in airplanes) into a Bluetooth signal that is compatible with any wireless Bluetooth headphones. It offers 16 hours of playback or continuous playback when connected via the included USB-C cable, allowing the Wireless Flight Adapter to stream throughout the entire flight and much more. With a range of 10 meters, you can stand up and move around without missing anything. The modular 3.5mm connectors retract into the sturdy adapter housing when not in use. Use just one connector for standard analog audio devices like MP3 players, portable consoles, or fitness equipment, and both for in-flight entertainment systems. Watch the same movie. Share a song or your favorite podcast. By briefly tapping the button on the wireless adapter, another headphone can be paired, enabling simultaneous audio playback.
