Unfortunately I had to return the headphones, as they were for me as a woman with a smallish head too big and have found no hold on me. Quality itself was not objectionable, the sound is fine, as well as operation. Only the rear bracket stood by me from a few centimeters, so that the headphones naturally slipped and thus out of the question came. Have found another, adequate headphones that fits.
My rather poor rating relates solely to the fit and has nothing to do with the quality. In my opinion, it should be mentioned in the description that the product is not suitable for small heads ....
