Smart earbuds that listen to your heart could lull you to sleep

This trial tests a pair of smart earbuds that use artificial intelligence to adjust soothing music in real time based on your heart rate and movement, aiming to help people with chronic insomnia fall asleep faster and sleep deeper. Adults with chronic insomnia will spend three nights in a sleep lab, trying both the AI-adaptive music and standard non-adaptive music, while researchers compare the earbuds' built-in sensors against clinical sleep monitoring equipment. After the lab phase, participants use the earbuds at home for two weeks. The goal is to see if personalized sound therapy can ease insomnia and if a consumer earbud can track sleep as accurately as a hospital system.
