Hey ya'll I have a quick question about the build quality of the 650's. I recently ordered a used pair off of eBay that were supposed to be only a month old. Yet something seems off. The sound quality is superb, so the drivers must be fine, but in regards to the actual build of the headphone, it seems like the the part connecting the headband to the actual headphone is loose (I don't know exactly what its called, the part of the headphone that says HD650 with the Left and Right indicators below them). The right side swivels much more than the left side, and occassionally creaks
Does this imply that they're about to break? Or is it just a little worn down and still have plenty of years left in them? After using them all weekend it hasn't seemed to worsen, I just wanted to know about how long these 'phones last.
