Mood Light Bluetooth Speakers for Home
The Bluetooth speaker comes with 64 million colors of lights, which will change and flicker with the speed of the music. When the volume of the Bluetooth device is at 80-90% of the total volume, the light will flicker at a high frequency with the speed of the music. When the volume of the Bluetooth device is at 70-80% of the total volume, the light will flicker at a low frequency with the speed of the music. When the volume of the Bluetooth device is below 70% of the total volume, all 64 million colors of lights will be automatically turned off, and the Bluetooth speaker system will automatically enter the hypnosis mode. At this time, the sound it plays is like a lullaby, giving people a comfortable rest environment. In addition, press and hold the power button for 3 seconds, and the Bluetooth speaker will enter the night light mode (i.e. warm white light lighting mode).
