I think the Edition 8 is the best thing I have ever put on my head. For me personally, it hits every note perfectly. Subwoofers with perfectly forward mids and nicely detailed highs. Of the hundreds of headphones I have owned in my life this is the one that will never leave my wall. I will buy more headphones just as a change of pace and because it's an aweful habit!
The Porta Pro is one I have been coming back to faithfully since 1986. There is just something about that Porta Pro sound that I like. I have gone through soooooooo many portable headphones over the years, but the Porta Pro keeps getting the most head time.
