When googling for the best in-ear headphones I am always met with the Shure SE535. Initially I was put off getting the high price. Following the motto "you only treat anything," I have but then slammed shut. Delivery went like always perfect on Amazon. But before you can hear the first sounds from the Shure SE535 is needed at all reasonable zubekommen a small training course to it's ear. At the relatively thick cables and the unusual shape of the listener needs some getting used to. It is also necessary from the wide range of foam / rubber articles to find the right for his ear. But if one is all managed to get an incredible sound. Whether he really is 4x better than that of my previous 100-Sennheiser earphones I do not judge. But in any case it is again a significant increase in the intensity and clarity of the sound. I am particularly impressed by the clear and extremely intense bass (you have to push the listeners, however, already quite deep in the ear canal or screw in). After a few days the handling is no longer an issue. I sit now the Shure as fast one, as the previous. Wen so the price does not bother who has with the Shure SE535, the near perfect in-ear earphones.
