bcpk: Excellent question. The real answer is that I enjoy the overall Ety sound. I'm really into detail. If there was another headphone option that offered similar detail PLUS clear, accurate, visceral bass, would definitely consider it... especially if it didn't require an amp when using a portable source and was offered at a price point that would not make my better half go completely bonkers.
That being said, I was intrigued enough by the comments here and the sale price to order a set of RE0.
Thanks for the advice folks!
ive only had them 48 hours (used for like 20 of that ), but i have to say, i havnt regretted the decision at all. they are awesome.
