Query: Oh, dear...........

This is the worst headphone I have ever bought.It's actually quite sad. The sound is great. Problem is - on your ears, the little 'phones stick <i>away</i> from your ears.So there is: - NO MUSIC THAT U HEAR - NO ISOLATION - LOTS OF AMBIENT NOISE - NOT HIGHLY EFFICIENTAll in all, great headphones that refuse to let u listen. QUITE ANNOYING. And I shelled out $10 for these. Oh, well........IF YOU HAVE A HUGE HEAD - the problem of the speakers jumpin away from your ears at an akward angle is non-existent. My sister uses these phones, and she loves em. If you're like me, and have an average-sized head, or have an average-to-small sized head without any hair hanging down, these probably won't fit on you very well.
