So I got my bosshifi b8 un-crosswired. Sounding about the same so far. Man that was a pain in the butt though. I recommend just buying the one off Amazon then in the future. You pay a bit more, but you get a case with some extras for that. Not to mention easier returns. Worth it in this case.
So if they were wired out of phase, they should sound very different now. Or were they wired in-phase but just had the R and L channels swapped?
