Great for the S-Bahn, too hard to run

I drive every morning about 40 minutes S-Bahn and've always used an in-ear headphones. With the Sony MDR the sound experience is quite different: the fact that the ears are completely enclosed, it is "totally isolated" from its surroundings in positven sense, ie the sound experience and the whole tram ride are thus really become very relaxing. The sound quality I feel - especially when compared to my previous in-ear headphones - as very good (although I miss the comparison with other fully-enclosing headphones).

Say negative, I want, I feel the headset too heavy to walk with him (of the race I do not want to talk), ie through the steps / the movement "teeters" headphones noticeably up and down. I use it therefore exclusively in the S-Bahn or home.

A note in the context of use with an iPhone: Several reviewers had reported here about bad results with iPhone (interruptions, etc.). I have also observed this with iOS 6; iOS 7 since the situation has improved massively, ie it only comes rarely to very short interruptions. In my view, therefore, recommended also for iPhone.
