Unlike the Koss the centers are clear and stand out better from the depths off. The bass is powerful and round, but not drowned as with Koss. Alicia Keys, Ayo, Corinne Bailey Rae, Norah Jones ... sound very good. The headphones has no noise to poor audio sources such as the high-sensitivity earphones Ultimate Ears.
Do not press on the ears, but they enclose the ears not completely, so they often initially around pushing to achieve the perfect fit. He is not well ventilated, so that one often has a humid throng on the ears. The cables to the volume control is too short for large people to disappear the volume slider in the lower pocket (in your pocket already not). Sounds good to iPhone / iPod, an MP3 player with EQ (iriver) and iMac. At first I found the volume control rather superfluous, but at the supermarket checkout time needed to get off than to the MP3 player, because he always hangs out.
The headphones themselves appear very valuable and robust. The cable is thick and durable. The plug is not gilded and a little too long for my taste. The volume control is made of very light plastic and looks a bit cheap.
For the price it is a very good sounding, robust headset, which can be well stowed in a jacket pocket.
