Or is there some kind of glue that holds them in piece?
EDIT: Also, you did burn them in pretty well before you returned them, right?
Every headphone has its own frequency response curve -- i.e., at a fixed input volume, some frequencies will come out of the phones sounding louder than others. (When I was trying to explain this to a coworker, he said "Oh, so it's like every headphone has a built-in equalizer?" That's as good a conceptual description as any.) So for instance, if you're trying to listen to something in the middle frequencies and turn up the volume to where the midrange is comfortable, you may find that the highs are then too loud and piercing. It's very much a matter of taste and preference how you react to a particular headphone's response curve. Many people love the V6's, others hate them, and both sides frequently cite exactly the same reasons.
With closed phones, isolation is a matter of how much outside sound they block. Open phones do leak sound out the back so that other people can hear it, but with almost all closed phones it's not an issue at any reasonable listening volume.
There's an old thread around here somewhere describing the exact process of swapping out the V6 pads for the Beyer pads, but it'll be tough to find until the search function is back online. I believe the V6 pads have a tight "collar" that grips a groove around the edge of the earpiece, so you just peel it out of the groove and slip it off the earpiece, and the Beyers go on the same way. I also recall that the V6 earpads include a foam "cover" that hides the drivers inside the earpiece, while the Beyer pads don't (since on the Beyer phones, that cover is part of the earpiece instead of being part of the pad). So you need to transplant that part when you put on the Beyer pads, or else the V6's driver will be exposed. Hopefully search will be back up soon so you can read the details.
And yes, I did give both sets of phones a decent burn-in while I had them. The HD280's are infamous for requiring a really long burn-in period to start sounding good. I gave them about 400-500 hours, and the sound did change a lot over that period, but they still didn't sound good to me. I think the Sonys got about 70-80 hours of intensive burn-in. So the sound had pretty much settled down when I made my decision.
