Consumers worldwide were shocked after a new laboratory investigation found dangerous chemicals in multiple headphone models from well-known brands, including Bose, Samsung, and Sennheiser, which may disrupt hormones and increase cancer risks.
According to a report by The Guardian, all 81 headphone models tested contained toxins linked to serious health risks, prompting experts to warn that millions of users globally could be affected.
The testing was conducted by the ToxFREE LIFE for All project, a collaboration of civil society groups in Central Europe, which randomly purchased both over-ear and in-ear headphones from retail stores and online platforms.
The test results revealed the following:
BPA (Bisphenol A) was found in 98% of samples.
BPS (Bisphenol S) was detected in over three-quarters of the samples.
Phthalates, chemicals linked to reproductive toxicity, were found.
Chlorinated paraffins, associated with liver and kidney damage in animal studies, were detected.
Brominated flame retardants and organophosphates were also present.
These substances are classified as endocrine disruptors that can mimic the body's hormones and are linked to cancer, developmental disorders, and neurological problems.
Although many samples showed low levels of these chemicals, chemical experts warned that daily prolonged use—especially during exercise involving sweat and heat—may accelerate chemical absorption through the skin. Nowadays, headphones are frequently worn during work, music listening, exercise, and relaxation, making them everyday items.
Scientists also highlighted the risk of the "Cocktail Effect," meaning the cumulative impact from long-term exposure to multiple hazardous substances simultaneously. Even if each chemical's amount is low, accumulation from various sources could increase health risks.
However, major audio brands mentioned in the report have not immediately responded to media inquiries, leading health activists to criticize the electronics industry for lacking transparency about the materials used in their products.
Researchers called for stricter regulations and limits on the use of hormone-disrupting chemicals in consumer goods, especially for children and adolescents, who may be more sensitive to hormonal effects.
