When I got my speakers a couple years ago, I read a LOT of reviews on forums, online magazines, etc. I also demoed five pairs in my home, and countless others in various stores. I drove an hour away sometimes to hear a particular speaker. With IEM's it doesn't seem to be that easy. I used a few mail order companies' free 30 day in home demo for the speakers, but I assume there's no such thing such thing for IEM's. I don't want to just buy a product I haven't heard. I've never owned good headphones before, and I've decided that IEM's will work best for me, but I really don't have a sense for what bass heavy, bass light, soundstage, etc.even sounds like in an IEM. I know the concepts, but I don't know what to expect out of an IEM at all. With speakers I can compare written reviews against personal experience, with IEM's not so much. I've been reading in the forums a LOT, but I feel that I've hit a wall. There's no going forward without hearing some models to get an idea of what's up. I live an hour north of Philadelphia. Suggestions? Any mail order places with liberal return policies?
