The Insignia 3.5 mm to Bluetooth Audio Adapter is a unique adapter both transmits and receives signals, which means the same accessory that lets you play music from your phone to your car stereo can also send the audio from the airplane movie to your wireless headphones. And you no longer have to share headphones to watch the in-flight entertainment—transmit mode can pair with multiple devices, allowing you to sync up both sets of headphones.
