You should buy these even if you have better headphones. Also they havent stayed fluffy on the inside. The bed of the shoe is flat and not much support or cushioning. They were at a promotional price I think as it was under £10 and with Prime delivery, perfect deal so. Die Größen stimmen auf gar keinen Fall, ich trage Gr. It is all you need and should take you no more than 15 minutes once all the pieces are out of the packaging. Then I wait a few more seconds for it to come back on. I over tightened and stipped the prior one (genuine part) by tighting it too hard, and had to replace the whole conductor plate with bapmics one. Excellent comfort, true to size. When I came back to them, they had shrunk!
