I'm with elnero on this one, and agree with his very nicely put impressions above. I understand how we all hear different and how different things come into our perception of sound, but man those ety's kill me, really bright sounding to my ears. The E500's have a more natural tone with more weight to the sound, they do somewhat remind me of cleaner, more detailed senns. Regardless, those two are on the opposite side of the aural spectrum for sure.
