AirPods Pro have a strange smell on its silicone tips, is that safe?

Hi. So, I returned and purchased a new pair. Same issue, though these smelled slightly less toxic. The rep that helped me return the previous pair said they'd not heard about a smell (not that they would tell me). I believe the only solution for this is time until Apple figures out why these odor is present. Hopefully the odor isn't actually toxic...

A few more thoughts:

1. Given that I've now seen this with three pairs, my assumption is that ALL AirPods Pro have this issue but only some of us care enough about it to be here.
2. This is likely some chemical used in the manufacture of the case or of the components inside the case and the silicon ear tips simply absorb (and reemit) the smell.
3. I'm hoping that Apple does fix this and that at some point it'll be possible to swap the charging case for one that doesn't stink. If it happens, I'm guessing there's no announcement. We'll know only because new units no longer smell. Since this could take until the next generation of AirPods Pro, I'm just going to use these and do my best to air them out.
