Sony XM4s blow the AirPods out of the water for me. Not much difference in price too.
If you care about SQ so much why would you even go near blu tooth devices??
Gotta go balanced and corded of course. My 3 year old IER-M7s are finally coming into their own and mellowing. I didn't like them for the first 2 years, I never did that continuous play burn in thing tho coz I thought they'd wear out, also probably less than frequent use since my commute has only been 20 minutes. Only really use em on long trips..
