I bought two pairs of these, as my four boys are always losing or breaking headphones.....usually one ear stops working. However, bought these as were a reasonable price. Needless to say they have stood the test of time, mainly because they won't use them. I have even tried them myself. The sound seems fine - not that I am a connoisseur, but they squeeze your head so firmly, that after only five minutes you have to take them off because they hurt your ears and actually give you a headache. My recommendation would be only to buy them for very small children if earphones are required, but even then, kids heads are almost adult size from a very young age.
Low rating given on comfort - or lack thereof.
