Great quality pad, excellent fit. Does change the sound signature but this is what I wanted.
Build quality: Excellent build quality, the fit is perfect for the HD800S. Pads feel very good, it adds some clamp in a good way, since they feel loose with the og pads. Sound wise: I got them with the intention of lowering the treble peak. It achieved that. Detail goes down, but its well worth if you find these sharp. It also made the headphone quieter so you will need more power to reach the same level of volumes (from 72% to 77% on my amp).
