When I purchased a DT880 around the time I joined this forum I purchased two of them; one to leave at work and one to leave at home.
After getting a work-from-home arrangement w/my company, I pretty much stopped listening to headphones as I could crank speakers; but recently returned to them. I realized only recently however that the DT880 set I had at home got damaged from a leaky roof that took me years to find the source-of and finally and repair. So now I have a DT880 set that looks near perfect (would want to change the earpads), but the drivers no longer work.
I was going to send [or bring] them to the guy here on LI who repairs Beyers; maybe even upgrading to a 'T' driver if one can fit. But, I wonder.... is there another non-Beyer driver you think might work well/great in the DT880's earcups? I've even been toying with the idea of an ortho driver transplant; probably dyi.
p.s. as to my skill level, I've never take a pair of headphones apart let alone played with or changed their drivers, or made a ortho headphone but have seen some dyi threads about it. But I've made plenty of custom speakers, some very successful.
