If I were to name a part of the K7xx's build quality that needed an upgrade it would never ever be the annie pads. I think they are the most comfortable pads I've had on a headphone!! That said I like pads and swapping them and I might go for the hybrids...
PaperdragonsI've had my annie's since day one and I've never swapped the pads. Easily my most comfortable headphones. Hell, AKG replaced my headband for free when I told them some of the plastic was cracking (which is amazing considering how old these are now).
