I have previously had in-ear headphones from AKG and was time well satisfied. However, just went after 1,5 years from now on after broken. The membrane of the earphone seems to be defective, he has only smashed and vibrates was clearly heard that it is defective. On Amazon I then searched and have become aware of these headphones, because they have received a positive review. "For the money, I can not do anything wrong ...", I thought to myself and ordered the headphones. I was very pleasantly surprised! The headphones are great, give a dynamic and rich bass and great highs. Personally I like them very well and I can recommend them without exception. Above all, I am pleased, because they were so cheap and still play saugut. * Thumbs up *
