Query: dont buy it

I returned this product because it had a constant buzzing on one side of the headphones but I would even return it if that werent the case. It doesnt fit around your ears at all- there is a gap between the headphone and the ear that feels very uncomfortable. The quality of sound is also poor. It is made of cheap material altogether. The controls are also hard to get used to. It looks brilliant when you think of it- mp3 player on headphones! But it doesnt work at all.
