The AKGs are comfortable, but I prefer the Beyers still. They are heavier, but the fuzzy gray velour really is plush against your skin. You'll forget you have them on, whereas the pads on the AKGs can get tiring on your face. They seem to get a little hotter, but unlike pleather, they don't get sticky and annoying. If the Beyers are a 10, the AKGs would be maybe about a high 8 to mid 9 IMHO. But I have a big head, so....lol.
The AKG definately has better mids than my Beyers. But the Beyers have better Bass and highs extension I would say, and more bass impact (not by much). Neither are gonna be Rock and Roll Phones though, though if you like tight bass, the Beyers really shine. They are both fairly neutral...just a different kind of sonic signature. It depends on how your music was mixed and what dynamic ranges are available. Classical Cello for example sounds gorgeous with the AKG, but Violins and high winds sound great on the Beyers. Tenor Saxes and Acoustic Guitars sound great on the AKG, and Alto Saxes and Piano sounds great on the Beyers. And etc etc etc....
If you can only buy one (yeah right!) then I would personally go for the Beyers. They are a better overall value I would say. What you lose slightly in the mids compared to the AKG, you gain in everything else. Hope this helps.
