I have a high-end in-ear earphones searched for my electronic drum Roland and so tried a few. There are many good products for a lot of money, but few seem to convince. It was only after the recommendation of a fellow musician I came to the Shure SE535. The purchase from Amazon was used well. The most worried I had to find matching ear muffs. After I had tried some but immediately came to enthusiasm. This has been the first in-ear earphone in which the basses do what I expect from an earphone, they come perfectly an.Der sound is clear and the best thing I've ever heard of an in-ear. Prerequisite is indeed the perfect seat of the ear muffs because everyone should try. But there are enough to choose from included, should not be a problem. Too bad that the ear muffs are a bit difficult to change. Man has this fear, cancel something. Judging but careful about to, that's no problem. The in-ears themselves fit perfectly in the ear because moves even with strong activities nothing. This Shure is certainly not the best. But if you're willing to pay a price for quality, then it is thoroughly recommended. I'd buy it at any time again, therefore, clear 5 Stars.
