European retailers pull popular headphones due to hormone-disrupting chemical contamination.

An EU-funded study has identified hormone-disrupting chemicals in a range of popular headphones from leading brands, prompting several European retailers to withdraw some models from sale. The investigation, which analyzed 81 types of headphones, found that all tested products contained trace amounts of the chemicals. Bol.com, Coolblue, and Mediamarkt have stopped selling affected models, while other retailers such as Apple, Beats, Samsung, Bose, JBL, and Sennheiser are also reviewing their product lines in response to the findings. The study’s authors called for greater transparency and regulation in the consumer electronics industry to address the issue of chemical contamination.
