After browsing the net to gather some opinions on quality headphones, cheap, my choice fell on it. I do not regret that choice. At first listen I was immediately seduced by the sound quality by listening to CDs on my hifi. I had the opportunity to test it with my mp3 player in-store compared to more expensive products but more adapted to mobility. At level sound quality, no problem. It is a bit bulkier around the neck (large atria) on the head but it is also lighter. That's why I put versatile. It is rather for listening indoor but occasionally it can bend and enters the pocket of a parka or jacket, so that you can travel with. Not practicing jogging or public transport every day I can not say more on this. I am now waiting to push him into a corner man in studio to see if I have to choose something more professional for that use. The short cable is an advantage but the move is problematic listening inside. There are Extensions of 3 m for 3-4 small jack. With the large jack adapter supplied, is happiness for under 35.
