The only complaint I still have with this headphone is the creakiness when I move my head around while wearing them, or when moving my jaw (for instance, while chewing on something). It's not anything that lubrication can fix. I think it's just a design flaw. It annoys me everytime I put them on. Otherwise, the SQ is still fantastic.
And for you guys wanting a bit more padding and space between your ear and the drivers, buy the Shure SRH840 pads and install those on the 7520. They'll fit. I've been using them for months now and the comfort is much better. It only very slightly adjusts the sound signature (emphasizes the bass ever so slightly).
