This sounds overblown. There’s no direct link to any study in the Guardian article, nor in any of the similar articles that came out today.
Searching ToxFree project got me this site, but skimming over this I couldn’t find anything with “headphones”.
Some other terms got me to ToxFree Life for all, but that’s just the petition without any research either.












I agree that it’s important to look out for risks, but the snippet “feminisation of males” just screams right-wing hit peace. That’s not made better by the fact that most publications don’t even link the organisation or the study.
So spent some more time tracking this down
The PCGamer article (released 2 hours ago) at least links the organisation behind the research.
Clicking around on their site I finally found the original piece (in hungarian) they made. Unfortunately it’s paywalled
