No. They will not stream your own music, audiobooks or podcasts. Instead, they play specially curated relaxation content to help you fall asleep and masking sounds to keep noises from disturbing sleep. In order to achieve a form factor small enough to be comfortable for sleeping and accommodate a battery that can support sound playback for an entire night, we made the conscious design decision not to stream audio to Sleepbuds. Instead, the sound files are stored on each of the earbuds and played back locally, dramatically extending the audio playback time achievable in this tiny form factor.
