You're limiting yourself to Best Buy?I think a better policy would be to find a place which allows you to listen, and then return if you're not happy. I think headroom (headroom.headphone.com) will allow you to do this.ff123
What about these? I'm trying to find something here, since I completely object to buying stuff online(credit card, shipping charge/time, not knowing what it is) unless it's something I can't find in stores anywhere.
However, the Sony 7506's (consumer version is the V6) are commonly used by sound engineers (so I'm told), so if you do lots of sound work, maybe those are the way to go.
