Conclusion: Pros : Light and comfortable, very well balanced frequency response. Cons : The plastic construction is flimsy, the cable is tick and stiff (I have already changed it). Overall it is a very good open headphone considering the price.
Summary: In short, they make Justin Bieber sound amazing. Sound is just amazing and at a reasonable price. Personally, I couldn't tell any difference in Audio Technica's Mh40x which my friend bought recently and these. Played my guitar and the clarity was exactly what I was looking for.
Summary: Beyerdynamic has always delivered products of good quality and this does not disappoint also. the build of the headphone does however look a bit flimsy with the plastic band, but the ear cups are very comfortable. The cable is a very thick cable with gold connectors at the end.
Summary: Very good indeed - extremely comfortable, and highs and lows exactly where you'd expect. Only snag is that their accuracy can expose deficiencies further up the chain - on a cheap'n'cheerful CD player they sound fantastic, but on my iPod I get a confused midrange.
