My main goal is to get something that sounds really excellent and is totally portable. Sitting at home and listening is all well and good, but I'm rarely at home and I want that amazing sound everywhere. I'm mainly looking for an absolutely huge soundstage so I can just feel like I'm in my own little music-realm when I close my eyes. To be honest, the HE-500 doesn't have all that much of an expansive soundstage. It sounds like it should have an expansive soundstage, but you can still clearly tell that you are listening to headphones. Despite that rocky-road frequency response (Which I am aware of), I'm sure they can help deliver that. Beyerdyanmic wouldn't release such a high-price item if they didn't think it sounded good.
By the way, just look at Grado. Many people like their products and they are voiced totally by ear to the "house sound". I figure these were voiced the same way in order to achieve the effect of having a much larger soundstage than what you would expect on a portable, closed headphone, thus the reverberation effect. Again, exactly what I'm looking for.
If you have any better recommendations, I am welcome to them!
