I changed the pads to hybrids from brainwaves. It did change the sound, made it brighter so I eq'd it. I also notice that if I push in the ear cups it sounds better(better seal, closure to the drivers), so I hope they conform better to my head over time. If they just made them thinner, they would be great. I originally bought the pads for the Meze 99 classics, but I wouldn't suggest these pads for them. The soundstage sounded odd to me. But the Nad headphones, it was worth it for the comfort. For 125 USD I think I ended up with really good sounding and comfortable headphones after all
There hard to fit, but its manageable.
