I have a set of DT100 headphones, and the leather was cracked from years of use. I bought these for more comfort. Its like a new set of headphones, warm to wear, and I can wear them for longer periods of time. I definitely prefer these velvet type as they don`t seem to stick to your face and irritate your skin, like the plastic or leather ones do. The packet they came in had the inner foam too for inside the the ear piece. They were easy to install and look very natural. they look and feel very durable. The isolation has definitely improved on my set since I put these on, because of the snug firm fit. I heard tales that they warm the sound a bit too, less shrillness.... ? I listened closely, closer, then closer. I nearly heard it! But I wouldn`t know about that.
