The headphones above are actually the ones I upgraded. I had used them on and off since the late '70's. After much consideration, I decided to go with the beyer dt250's. I ordered them from headroom using the 2 day delivery. To my surprise, they arrived all the way from Montana to PA in one day!!! As you can imagine, I am very pleased with the sound but most of all the comfort.....wow!
I am glad I found this forum because there is a ton of info here that I was able to use to make my decision.
