Review on Enhance In-Car Entertainment: 4-Pack of Folding Universal Rear Entertainment System Infrared Headphones - Wireless IR DVD Player Headphones for TV, Video, and Audio Listening by Cody Mckechnie

Bought for my Yukon for my kids. Haven't had any problems yet. They've watched a few movies and I haven't had to change the batteries yet, so I'd say the battery life is good. The sound quality is good, I'm sure there are better ones, but for the price I can't beat it until I run into some hiss or something. I have a 5 year old and a 3 year old and they fit both, my 3 year old is a bit big but they work.
