Excellent sound, but I figured realized that once the open box that these headphones are not compatible with the Android system. And to my great regret, it only lasted just one year. Compared to other headsets in the market is not bad you will say to me then, for I was thinking that it would hold 40th more than that. But there's a little more that I appreciate is that the material or rather the shape of the wire prevents it difficult to unravel once pocketed. :)
