Very good velvet quality. The plastics on the inside are lower quality than the original, the padding is thicker and the hole for your ears is smaller, and pads sometimes fall out and dont fit fully but are functional and the sound quality is not degraded much comparing to the original. Would buy again, especially for the price.
The ear pads are of good quality and fit well with the Senns HD 6XX. In my opinion, the velour of these pads is better than the original ones. The hole is noticeably smaller than the original, and this can be a problem for people with large ears (image #4: original pads at the top, these pads at the bottom). I have doubts about the acoustic properties of foam discs. Of course, the sound has changed compared to the original pads, but it cannot be said that it has become much worse. Great option for the price. Thanks a lot to the seller!
