Super sound at an unbeatable price

In this price range normally found not reasonable, but in this in-ear headphone that looks quite different. The basses come across super. Even otherwise, the headset looks absolutely not tinny. I've previously expensive in-ear headphones used by Sony or Senheiser that were concerning the sound is not better but have sometimes tasted loose between 20 and 35 euros and after a half to one year or then have given up the ghost (one side was quiet or skipped entirely, presumably internal cable break). I use the In-ear headphones almost exclusively while jogging. This then sit on well and do not dissolve from the ear. A small smear have these headphones: the smallest rubber attachment is for me almost too large. I have difficulties to put them firmly into his ear. Had the speaker diaphragms perhaps 0.5 to 1 mm smaller from here through fair, that would certainly be easier. But perhaps I have also quite close ear openings. This slight drawback leads for me but to no star deduction. Who is testing these headphones, certainly comes to the conclusion that there is no better brand, what more sound brings. The value for money is unbeatable here.
