I'm sure these will sound good and be fun to listen to, however for me I am going to pass because I already own a HFI 780 (which I do really enjoy).
Awesome bass, sparkly treble. They are fun headphones, they don't need an amp either.
The S logic board looks basically the same minus the little fin part. I paid $80 for my 780, which is quite a bit saved vs. the X if they are as similar as they look.
I pulled up a measurement of the 780 vs this new signature X, IMO it looks almost identical.
I really do wonder if these are a re-branding of the older HFI series with new removable cables, fancy case, etc. Maybe this is totally wrong, but it basically looks the part.
And don't get me wrong, I would still like my 780, even for $250. It's just it wasn't and that's even better.
I think this may even be closer to the lower model 580 than the 780 since the 580 was the one with the 50 MM driver like these.
MSRP on 580i is $199, would make sense that they take that base, add the new fin, retune a bit, pack along a case and a few removable cables, fresh design, $250.
Again, not sure (by any means) this is the case but possible theory.
