Why? Because of what I said about comfort? Or because of what I said about the SQ?
If it's comfort, take that with a grain of salt as I apparently have a very picky head/ears. If it's sound, wait a few days as my impressions tend to change over time (either because of burn-in or me warming up to the headphone).
Edit: just for fun, I ordered a pair of Shure 1840 pads for the 7520, to see how it'll sound with that. Since it's velour, it will probably absorb most of the soundwaves caused by reverberation, giving it an overall more dry sound. I'm not exactly sure, but now that I'm comparing the 7520 (with 840 pads) to the 1540, I'm noticing a quality in the bass of the 7520 which makes it seem slightly emphasized. I will of course also install the stock 7520 pads later and compare with that.
But since the 1540 and 1840 are essentially the same size and the 1540 pads fit the 7520, I wanted to try out the 1840 pads as well. They'll probably arrive next week.
