I'm wondering the same. There are some master&dynamic models that are mostly made from metal/leather, but they're above my usual price range. I'm not really an audiophile, I'll settle for lower audio quality, but I'd prefer to wear one that doesn't have me constantly guessing whether I'm poisoning myself.

The PDF lists specific products and their results, Sony WH-1000XM5 look good, so do a few others. Purchasing a known-good model might be a good idea but I question how effective this would be, given potential variance in manufacturing processes between lots.

I use SteelSeries Arctis 1 which wasn't tested. The Arctis Nova 5 scored "red" for parts touching the skin though, so...
