First a thank you to Amazon for the quick delivery! The headphones Kahmen namely after 2 days on. The packaging is very high quality and leaves a lasting impression in advance. To Headphones more essays are also included (for small or big ears) and a bag, which I consider to be very practical, in the box. So and now to headphones se ... Typical Sony not only the packaging but also the headphone is very high quality and super. The noise-cancling system works without problems. And now the prop. For good, the sound .... which is, as I can only connect my predecessors, the best has to offer an in-ear headphones. The bass is very concise but not drown out the rest. The highs are incredibly clear and do not scratch off also in higher tones. Also the comfort is very good. That's my opinion all this criteria also appropriate. So ultimately I can only headphones empfelen and only again say that one of the award should not shy!
