These are perfect for backseat entertainment. Purchased four headsets for our vehicles. All four arrived perfect and worked right out of the box. No problems, just turn them on and go. The units fit both kids (2 & 5 year olds @ my house), and comfortably fit my wife and I as well (34 yr old kids). I would not hesitate recommending these to anyone/everyone as they seem to be solid performers so far. Auto-on/off feature helpful with the little ones to conserve batteries.
