sony mv1 or ma900?

i’m planning to buy new headphones. and i stumbled across these two but i couldn’t find a clear comparison. i don’t have much experience in the field, and never tried the ma900 so i’m conflicted between the two. which one is better? the “ma900” has a bigger driver which i’m not sure if better or not and is a bit lighter and made out of metal i found a post where someone said something about ear speaker-ish (i don’t understand what they meant) the reviews on the “mv1” were generally positive and tbh it requires less work to get where i live but i think i need a legit comparison it’d help a lot
