I think it's the mid bass - the planar is so quick that the normal amount seems short. But honestly not sure, they seem to respond to EQ differently than a DD. Need to spend more time messing around with it.

I just haven't managed to find eq settings I like for them. Normally I like Harman tuning, but it sounds hollow on the S12.

I've got the S12 Pros - when I put them on after listening to the Truthear Hola it feels like a veil is lifted.

They're pretty comfortable, which I suspect the other planars aren't.

Not a huge fan of the tuning, would probably be better slightly more neutral. But even so they're amazing.

Rest in pieces

I'd just be happy if the fish at my local wasn't some kind of shark at this point.
