Do they need to be connected to a Bluetooth® device to function?Updated 3 months ago

Bluetooth® is necessary to pair the Sleepbuds® with your device. Once set up, it is only used to stream audio and switch Sleep Sounds and settings. If you would like to stream audio, then yes, you need to connect to a Bluetooth® device while listening. You will also need a Bluetooth®-enabled device to set up the product initially. Once your Sleepbuds® are set up, you can use the Ozlo Sleep Sounds without the device. Switching the Sleep Sounds, volume, and settings, though, will require a connection.
