Not sure if anyone discovered this yet but the Urbanears Zinken pads are quite a good option for the ATH-ES700. They only cost 5 USD and are MUCH plushier than the stock pads, its like having cushions on your ears. They also do not seem to affect the sound a whole lot, or at least I can't hear a big difference. I think they attenuate the treble a little bit, but otherwise they seem to sound pretty much identical to the stock pads. Stock ATH-ES700 is just slightly dark and these pads make them a little bit more neutral to my ears. With the already fantastic midrange and a slightly added treble bite, these become ideal for rock! At the same time, I can't hear any ugly sibilance anywhere (I also tried the Zinken pads with my JVC HA-S500 and the result was an unlistenable, biting exercise in sibilance). They also don't affect the soundstage by any margin detectable by me.
The only caveat is that being quite a lot plushier than the stock pads, the clamp of the ES700 becomes quite worriesome and I'm forced to adjust them two whole notches above what I'd usually have them at on the headband. Its not uncomfortable but feels a little more claustrophobic than stock. I'm quite excited to see what happens when the pads adjust to my ears over time.
