The sound quality for an average person is really good, even with loud music. The call acceptance function works very well. I use these headphones very much for calling and listening to music when I'm traveling. Annoying is something the transfer of cable noise. Especially if you are traveling outside and the micro times comes to the jacket, it hears the other person immediately. Very well-fitting ear pads that you do not lose as quickly. Relatively thin cable but are well sealed against cable break. The processing makes a solid impression. But on the whole I am satisfied with the headphones at the price-performance ratio. This is already the 2nd pair of what I bought.
