The SNUG children headphones are currently the new favorite toy of our great Daughter (4 years).
The sound is somewhat muffled and is not just a very high level, but it is also far better than you would expect at first glance. For children's songs and radio plays it was good enough. Unlike ear plugs, which in children sit badly and that they themselves can not operate well often, overEar headphones like this one are perfect. We run this with a small MP3 player with a AAA battery and it now holds since 3 days the stresses of our daughter through. At a party we have also been approached by other parents who also search for appropriate solutions, the example. The old Walkman headphones slip quickly and can not adjust the strap on small children's heads. In addition, the headphones dampen the sound from the outside, what with eg. Weddings for young children but quite fast too much can be. Here the child can possibly withdraw his own music or radio play and stay still sit with Papa on the lap :-)
