I had it all, from Sony to Sennheiser and many were extremely fast broken or have somehow lost in sound intensity. So long as these headphones, as yet no thought. Had she now over a year and they've unfortunately lost last weekend and will buy me one more time. Sound is definitely very good and people who do not buy 50 euro or expensive in-ear earphone, will make us very happy. People who previously bought the headphones always 10-20 euro range, these feel definitely very good sound :)
