I know a few people bought them last year when Equations were the FOTM. I don't know how many people still have them. Do a search and you should find something. Look for the long thread on the RP21 and RP22x started by dandi. I'm sure they're talked about in that thread.
I still have my RP21 although I don't use it much. They don't isolate well enough for me. If you need isolation, I'm pretty sure the RP15 won't work for you. I personally haven't found any headphones that isolate well enough. I stick with IEMs.
