They’re so easy to use - just pop your earbuds into the adapters, clip them to your waistband and feel baby move! Wear from the beginning of your second trimester through delivery. Includes access to 2 free playlists, accessible through Spotify, iTunes and several other music apps to help you choose calming classical or energetic music for baby.
