Overview
- Civil-society researchers with the ToxFree LIFE for All project purchased 81 in-ear and over-ear headphones for laboratory analysis.
- Hazardous substances were detected in every sample, including models from Bose, Panasonic, Samsung and Sennheiser.
- The report points to dermal exposure during regular use, noting that heat, sweat and mechanical stress can accelerate migration from hard plastic parts.
- Many chemicals were detected at trace levels, yet the researchers warn that long-term exposure to endocrine disruptors remains concerning, particularly for teenagers.
- Campaigners call the findings a market-wide failure and urge regulators to ban the most hazardous substances and establish stricter rules for wearable electronics.
