These sounds transport you to the soothing atmosphere of nature and help relax your body and mind. You can turn on the speaker at night to create a peaceful sleeping environment that even calms crying babies and helps them sleep through the night.

A long press turns the device on, and once Bluetooth pairing is successful, you can enjoy your favourite music. The next time you use it, the device will automatically connect to your smartphone. The timer function allows you to play soothing music for a set amount of time, saving power. Compact and portable: With a diameter of only 8 cm, the speaker can be placed discreetly under your pillow without feeling intrusive.
