I’m gonna go a bit against the grain here. I’ve tried several IEMs from moondrop starfield to campfire andromeda and they’ve all sounded like shit compared to HD600s or sundaras. Basic speakers like LSR308Ps are way more enjoyable than any headphones imo, especially with a decent subwoofer. I’d go as far as to say if you have any reasonable private listening room headphones shouldn’t really be in the discussion. No headphone matches the visceral experience of well tuned room-filling bass. I’d even take my (fairly extensive) car system over any headphones I’ve ever heard 10 times out of 10. Just IMO of course.

Frequency response graphs show the most important single metric of a piece of audio equipment—the linear distortion. Linear distortion is far more easily audible and objectionable than nonlinear distortions. I don’t think anyone claims that FR is ‘everything’ but it is definitely the most important thing.

Still too expensive tbh. Even if they halved this price I’d take the HD560S over them.
