Struggling to sleep? Tim Antos did too. After he learned how different sounds can facilitate sleep, his company, Kokoon, developed NightBuds. As a user listens to music, a podcast, or Kokoon’s library of sounds, NightBuds’ biometric earbuds—just 5.4 mm thick—sense the wearer falling asleep and then fade to gentle white noise. Loud traffic disturbance at 2 a.m.? NightBuds’ dynamic noise masking dials up the white noise. The MyKokoon companion app provides long-term insights to improve sleep quality. “We all sleep, and we can all do it better,” Antos says. One company study found that 2,000 users spent 15% more time in deep sleep (on average) after using NightBuds for one month.
