How bizarre! When I had the T50 for a short while, once I got then pressed properly into place on my ears, they had some of the biggest bass I'd heard in a portable headphone. I mean, it was just huge, deep bass. So for Beyer to have backed off to almost a 'bass-light' phone is pretty weird. That would rule them out for me.
Maybe they tuned it the way they did with T5p?
