SENNHEISER HD25 Ear Pad Replacement Black Protein Leather Good Sound Quality Black Replacement ear pads for the legendary HD25. Genuine products are probably over 5,000 yen. Made of protein leather, used in high-end headphones such as ULTRASONE, so it's extremely durable and gives a luxurious feel. Unlike the genuine product, there is no hard material inside, so the fit is softer. Since these headphones have a strong clamping force, they are more comfortable to wear for long periods. In my personal opinion, comparing the genuine product and the replacement, the characteristic around 125Hz in the low range is reduced, and it seems that even lower frequencies are produced. It feels like the range has expanded. I am selling a new, unused item that I had as a spare. It takes a little effort to put them on. Please understand.
