While the leatherette seems to be of good quality, they do not fit properly. There is a gap as shown in the photos, resulting in them coming off too easily. At this stage, I don't care that much since they serve my purpose.

material is not protein leather, its fabric. So far soo good price/performance

They are good quality but are very tight, resulting in discomfort if worn for a long time. They may soften over time. They definitely have a different design (narrower) than the originals.

Very good quality. It will show how long they will last, they are just a different shape from the genuine ones and they didn't suit me so much.

They came in fabric, (something I wanted because "protein leather" easily gets damaged). So far they are perfect, easy to install, fit well on the headphones, premium feel and comfortable!
