I was looking for a headset that I can carry around with me and that Sennheiser is ideal. He can bend and becomes very compact, then I just have to put it in the bag that came with and I can get it in a pocket of my coat. It really is perfect for those who want to enjoy their music at any time and who prefer headphones to the headphones without having to backpack to store a helmet too big. I have no complaints about the sound, I use it with an iPod Touch and for me it is useless to put hundreds of dollars in a helmet while with the PX 200 II was something very easily transportable, that offers its nickel. I had read somewhere that it lacked bass or other comments on the sound but frankly for the music I listen to (hard rock, heavy / thrash metal ...) there's no problem there. The headphone ear headphones cover just as it should be (it does not surround the ear is above) and honestly it still insulates better than what I expected. So in summary if you want a headset that you can take everywhere with her properly I can only advise you on!
