Upgraded my dad to QC35's and inherited his QC25's. Earpads were in moderate shape, then after I used them for a year I guess my stubble abraded them until they gave up. These were a Limited Edition QC25 that came with an off-white, light skin tone colored pads. I assume this is what Bose calls "white". I wanted something close to match the original but slightly darker without going full brown. These were perfect, plus the dust liners they came with were black and not blue, just as they originally came, (I think the non limited editions come with blue dust liners).
Installation was a snap, took about 10 minutes per cushion as I wanted to be precise and ensure all 9 tabs on each cup were secure. These pads are a perfect fit, no looseness or oversized or undersized fit, same depth as the original pads. They are slightly firmer and the protein leather is not as supple as the original, they feel slightly more durable but I haven't worn them yet.
