Sleep, sound, and the habits in between
Good sleep is shaped by more than a playlist or a pair of headphones. These figures put sleep habits and listening levels in context, using public-health sources that state how and when the data was collected. The listening figures are exposure guides, not a diagnosis or a substitute for personal medical advice.

Context matters as much as the number
Sleep figures above describe U.S. adults surveyed in 2024. They show population patterns, not the cause of one person's sleep difficulty. Listening figures describe exposure levels and duration together, so turning volume down matters more than chasing a single universal setting.
For bedtime audio, keep the volume comfortable, choose audio that does not pull you back to your phone, and use a timer when it helps the routine end naturally. Explore our sleep headphone headband buying guide for practical comfort and setup advice.
