I don’t even have these but from all the discussion and seemingly high praise, this seems like such a steal for these. And only $150 for the HD58x … I wish more of my friends would get stuff like this instead of paying more for what I (and probably many) think are inferior.

Where is a good place to look for second hand items? I’m always a little leery on eBay (if that’s even a viable option)

I haven’t tried these on, but I gotta say, I like the old headband on my DT770 better than this one. The pad is easily replaceable (tho I think this one is replaceable as well) and I like the look of it more since it wraps around the metal headband. They are super comfortable to me. However, the fact you can switch out cables on the new one is a huge improvement imo - and many others I imagine. I’m glad you’re enjoying them!
