I use UE Superfi 5 EB's and used to like them a lot. I think my tastes changed a little and I like better mids now. I just went to regular cans for that.

I bought new cables just when Logitech took over. I think there are other companies that make similar cables, you might check head-fi for referrals.

One of my shells is breaking so I'm considering have it reshelled. This place does it for $80. I just have to find a reasonable place locally to have the molds done. I figure it'll breathe some new life into the UE's, which I do really like for some kinds of music, plus they're WAY easier to travel with.
