Earphones of my daughter, not really known for its delicacy with hardware. That one month it has on the ears do not even have snatched anything, very good point robustness issue. The sound quality, always in this price range, is more than satisfactory. Low but not that much present, the highs are fine, precise and delicate. Tested on the famous "Cologne Concert" by Keith Jarrett (the test kills) where the entire sound spectrum is represented, I can not admit being pleasantly surprised I am more used to Seinheiser. I recommend very strongly, remains to be seen how long in time. Question delivery, Amazon presiste in excellence, hardly ever ordered in the mailboxes. Congratulations!
