Consumers worldwide are shocked after a new laboratory investigation found hazardous chemicals in multiple headphone models from major brands including Bose, Samsung, and Sennheiser, which can affect hormones and pose cancer risks.
The Guardian news agency reported that all 81 headphone models tested contained toxic substances linked to serious health risks, with experts warning 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 findings revealed that:
BPA (Bisphenol A) was detected in 98% of samples.
BPS (Bisphenol S) was found in over three-quarters of the samples.
Phthalates, chemicals linked to reproductive toxicity, were present.
Chlorinated paraffins, associated with liver and kidney damage in animal studies, were detected.
Brominated flame retardants and organophosphates were also found.
These substances are classified as endocrine disruptors, which can mimic hormones in the body and are linked to cancer, developmental disorders, and neurological problems.
Although many samples contained low levels of these chemicals, chemistry experts warn that prolonged daily use—especially during exercise when sweating and heat are present—may accelerate the chemicals' absorption through the skin. Today, people frequently use headphones as everyday items for work, music, exercise, and relaxation.
Scientists also highlight the risk of the “Cocktail Effect,” where long-term exposure to multiple harmful chemicals simultaneously, even at low levels, can accumulate from various sources and increase health risks.
However, the major audio brands mentioned in the report have not yet responded to media inquiries, prompting health advocates to criticize the electronics industry for lacking transparency about the materials used in their products.
Researchers are calling for stricter regulations to limit the use of hormone-disrupting substances in consumer goods, especially for children and adolescents who may be more vulnerable to hormonal effects.
