Cancer-Linked Chemicals Found in Nearly All Tested Headphones

A European study tested 81 headphones and found BPA in 98% of samples and its substitute BPS in more than three-quarters, with these chemicals migrating into wearers through skin contact—especially with in-ear models—raising concerns about long‑term risks like endocrine disruption, feminization, early puberty, cancer and organ damage. Regulators and manufacturers are urged to demand safer materials and transparency, with TOX-Free LIFE for All pushing bans; Bose and Panasonic were contacted for comment.
