Green noise is used to create a calm auditory environment without sharp highs or heavy lows.

Ideal for relaxation, focus, sleep, mindfulness, and ASMR-style calm listening.

Use at a comfortable volume and disable bass boost or equalizer enhancements.

Ideal for sleep, anxiety relief, deep focus, meditation, and ASMR-style relaxation.

For best results, use a comfortable low volume and turn off bass boost or sound enhancement features.
