Used XS or new HE-560 V4?

I’m considering a used pair of HiFiMan Edition XS for $450 or a new pair of HiFiMan HE-560 V4 for $229 from Adorama to replace or supplement my HiFiMan HE-400se. I like rock, classic rock, alternative rock, alt-country, Americana, bluegrass, hard bop jazz and progressive house EDM.

Which is a better fit and deal at those prices? Thanks.
