If i had to choose between the 4r and 535 though, i'm not sure which. The 4r sounds flatter overall, but also softer in a way because it has bloated mid bass. The 535 may not have amazing treble, but the linear bass and mids really give them a nice sound otherwise.
If i were going to use eq, i'd probably go 4r. They sound amazing with accudio or a few simple eq adjustments, and they're a lot more confortable to me. That's why the 535 didn't work ultimately... comfort. They're too big for my outer ear shape.
