I have plans to eventually write that comparison... however, I am currently too busy to write anything coherent or to sit still and listen to those two carefully. Under what I remembered, I think the SE535 does everything better except for the bass. That's not to say the SE535 does the bass bad, it is just that the EX1000 just does it so well.
Despite of the very tight, well-controlled, and powerful bass (tighter, but slightly less boom than the Coppers in comparison), the EX1000 is considered grainy with its treble for its price tag (I haven't heard its sibliance though interestingly). Mids are good, but compared to the SE535, it loses out there as well.
If you want to talk about value, I honestly believe the SE535 is a better choice. However, if you want an extra punch in your music and dislike the slightly rolled off treble of the SE535, the EX1000 can be a good choice as well.
