As for the sound, I must say I like it quite well. The music acts differentially oriented, and now I can switch between the mighty guitar, bass and drum set with Napalm Death, Misery Index and other grind bands properly follow and enjoy the go - no comparison to the Ipod headphones!
Unfortunately, the headset is now broken after 4 months, it has suffered the same fate as actually all my headphones - Cable break the plug :(
Nevertheless, I will bring it to me again, he has good quality and yet I'm still guaranteed.
But he only held by the same length as all my other headphones from Apple, Philips and Co, only 4 stars!
