I haven't tried 'em in a while and I actually tested all the tracks listed above right now.
Tbf, they did pretty well. I've got a Creative E5 which get most things loud - definitely a young budding basshead's friend. Applying any EQs, it doesn't like it, but without EQ, I can turn it up to ~48-50/100 before it starts distorting and that's more than most headphones would take before frying.
For example, my V-Modas get to the same volume at ~25/100 and to listen at 50/100 I need to do a -7db cut across the whole frequency range, however, no distortion is present in the bass.
On the other hand, at the 25/100 listening range I do a +8db boost in the 32hz region and the V-Moda goes nuts without issue. The Beyers at that volume sound like a fan and are much quieter (the latter being expected and excusable as its significantly harder to drive).
It just seems its not made for heavy sub bass, because wave gets transposed to the rest of the frequency response and it sounds terrible - that's why I could never recommend it as a basshead can. Great for films and everything non-music though. It does have extension, just not quantity and the vocal tracking is sublime which is why they use it at radio stations I guess. Plus they're super comfortable for long listening sessions.
But yeah trust me, I have put they Beyers through the ringer in the past. Thought they were broken so bought a completely separate pair and the performance was exactly the same, so I concluded that this is just how they are.
Bit of a shame tbh because it was so highly praised, but it wasn't from bassheads' perspectives, but audiophiles who are used to flatter signatures.
Everything is "extremely V-shaped" if you're comparing it to a HD 650
