Summary: I have ordered my Sony XBA-4iP after a really deep research and I had a very high expectations. When they arrived, at first I was very disappointed with the sound quality. It was very sharp, without any energy and the bass was barely there at all. And then I have read a very useful reviews, saying that these headphones need some 'warm-up'. And this is totally true. After roughly 10 hours, they started to sound better and better.
Summary: they look amazing, and have really nice build, but unfortunately they will only work with a ipod, the sound quality was terrrible in a normal device, but great in a iPod, the remote also only functions with a ipod and nothing else, so if you want to use this for a few things, do not buy it, shame sony has done this,
