Summary: Discovered new sound in the music I've been listening to. Great set of headphones if you are into classic rock. Not very useful for low bass sounds. I've owned these for five months now. Not planning on buying another pair soon.
Summary: Fantastic sound when used with Amps or iPhone (other portable music players available) Was interested when I first saw these come out, but at £40 - it was a must-buy. Others have mentioned questionable build quality. I've had mine for around 4 weeks now and can't fault them so far.
