As someone with the same issue (including multiple replacements).. I don't want a refund. I just want working ones. I really wish they'd fix whatever manufacturing defect is causing this.
It's frustrating. My airpods pro had an issue where they'd make a crackling sound with every step I take (but were fine when sitting). Apple replaced them in warranty and it's been fine since, but they now have a replacement program for these out of warranty as well.
I hope they're doing diagnostics on defective airpods they receive from customers.
