Only issue is that the cups aren't super big so if you have large or very protruding ears they won't fit.
I don't think that'll be a problem for me, my ears are definitely on the small/flat side. I'll await for the MM100s from Audeze first before deciding, but looking at the price and some graphs, I think the R70x will probably be a better fit for me compared to the DT 1990 PRO, as of now, I don't think I can justify getting the Beyers since they're double the price of the R70x for a, what I assume after looking at some reviews and such, not double the price worth difference.
I just wanted to thank you for recommending the ATH R70x, if the MM100s aren't accessible here on Brasil, I'll definitely be going for the R70x :D
Here's hoping that your Aryas last a long time! especially since you seem to really like them.
