Actually yes; I have the 650 cord which really makes the bass and drums come forward on the Sennheisers, whereas even though there is not a bass deficiency on the Ed-8's, it's just too balanced and I think I really prefer more upfront slam that I get on the 25-1's. For example I like to listen to the first two songs on the Jeff Healy "A Mess of Blues" album, and I just don't get the same feeling that like, I have to stop what I'm doing and just listen to the music because it sounds so good, like I feel with the 25-1's.
I'm on the fence on whether to keep or return the Edition 8's because I'm not sure how much I will prefer to listen to them. But they are the most comfortable set that don't press my glasses against my head. Like I said, I need encouragement to keep them. I did a search last week but didn't notice any review from you (I did think I found one short review from someone), although I did notice your comment that you think they are your best closed headphone (hope I got that right!).
