the sound be fine , but the head band be too tight . it press so hard against my ear that after 30 minute they hurt . so you think I be a Fat Head ! but no - I have a normal size adult male head . I have tie to bend the spring steel part of the band , but the plastic section be make with a small radius and can not be bent . I be sure unit be fine for kid and pea brain ! I also wish this only have one wire out the left side , rather than two wire -lrb- one to each earphone -rrb- . but most of these phone -lrb- except for the cheaper Sony -rrb- be make this way .
