Have read many recessions and Test Results. Eventually I had enough, because one says so and the other different. Since gemäkelt, and then the others complain because rum. Few who are satisfied with any earphones and have nothing wrong. There is always a gnat shit found, which gives rise to complain. I am very pleased with these earphones. Whether I now any treble, bass, bass and what else is there to hear it all, really top notch hear. I can put this super plugs in my ears, without these being a nuisance or my ears induce a rejection response in the form of itching. Even to fall asleep on the pillow they are top without pushing something. Would I buy it again! As a layman, I am very satisfied!
