They held up to a 10db bass shelf without distortion and the rest was a matter of defucking the hollow mids and nuking the mt everest peak around 10k.

They were then quite pleasing and balanced while keeping the planar traits like speed and detail. Still a smaller head stage by being IEMs, but very impressive for their size. I only use foam tips with them. They aren't quite as natural sounding as some dynamics, but it didn't bother me considering their other traits. And I genuinely couldn't go back to non EQ. Even my wife was surprised by them and she hates treble.

I do wanna try the Max, but just looking at it I know it won't be comfortable. I couldn't wear the FH3 or the Zu tan wu, I get ear pain/sore spots a after 15 minutes.
