The wearing comfort is due to the angled design that I did not know before, Excellent, you have the handset only once stuck in his ear, and they sit, as if they were not there. No slipping, no discomfort, no wherewithal touching up the position in the ear - just perfect.
The sound of my previous headset I felt actually already very good - the again significantly better sound of Sony's there almost a stunner, especially when it comes to bass - friends of bass-heavy music will get their costs. Otherwise true with regard to the sound and everything else, in any piece of music reminds me of a serious difference to my system at home.
The attenuation of ambient noise is properly even when there is no movement of the cable rustling or similar.
So I am very pleased with the Sony MDR-EX57LPB. Therefore, I find the price for money really good. The only thing I can not yet assess the service life - at least I hope, that I can still enjoy some time the headphones!
