Toxins Detected in Widely Used Headphones Raise Health Concerns
A TOX-Free Project study tested 81 headphones and earbuds from brands including Bose, Samsung, and Sennheiser, finding bisphenol A in 98% of samples and bisphenol S in over 75%, along with phthalates and other flame retardants. These chemicals are linked to cancer, neurodevelopmental problems, and hormone disruption; long-term exposure—especially with sweat during use—may pose health risks. The research notes no immediate danger but highlights potential long-term concerns, and mentions Apple has regulated chemicals on its list. The project aims to improve detection of chemicals in consumer products using nanotechnology.
