I bought one of these last year for the first time, as a probably-never-use-but-good-to-have and it was life changing. With the demise of Virgin Int'l we started using United and they don't offer the semi-quality headphones we were used to, so thank god for this device that allowed me to use my own headphones on board. I have since purchased more of them for the rest of the family to use, as we continue to fly United on our international travels and they still dont offer better headphones. Ha. Paired with the Kooshy headband headphones and the kids travel SO well on the 16-28hr journeys!
