Not all Beyers have flat drivers. The T1 line uses an angled driver inside the ear cup. Focal, Audio Technica, Sony, and some other brands also have models with angled drivers.

From what I've heard, the difference is not as pronounced as audiophiles think it is. Yes, it changes how the sonic wavefront interacts with your ears, but that does not intrinsically produce better soundstage or imaging. I've also seen cases where an angled driver actually hurts imaging accuracy by over-focusing frontal sounds and creating a dead zone to the sides (the Stax SR-L700mk2 has this, and my friend reported the same effect on the Focal Elex).

In headphones, you rarely can say that X feature always makes B property better. Feature X can improve that property if used in conjuction with other features that also help produce that property, but you can't take any feature in isolation and make claims about a headphone's performance from that.

Thank you!

Does it perhaps also depend on the individual using them...?

To give an example, could one person using angled-driver-Sennheisers (or anything else) get the same phenomenon as from those Stax SR-L700mk2, only due to that person's head shape?

Maybe. I didn't notice the weird imaging on the Elex to the extent that my friend did. I also wasn't impressed with the soundstage on the Sennheiser HD800S: it was the widest I'd heard by a small margin, but the increase in frontal depth didn't match the increase in width. I thought that many Hifiman headphones have a better soundstage presentation despite having flat drivers.

One interesting example would be the Ultrasone headphones and their S-Logic system. The drivers are not only angled, but placed lower and fire upwards at the ear. For some people, this produces a much wider soundstage. But other people's ears just don't work with S-Logic, so all they hear is a screechy mess.

I don't think it's with the goal of better imaging or soundstage. Having the drivers point towards your ears is better. It's like comparing speakers placed in front of you with speakers placed behind you, the ones properly facing you fun the front are better.

Also he asked about different head shapes and people wanting different angels. Gyrations aren't set to an angle, they have some rotation in the cups that can change delegating on who is wearing them, I'm thinking of the Hifiman Arya design that allows for infinite rotation of the cups. Even the Beyerdynamic DT 770 lineup has some rotation for the earcups.
