Play Button

The play button, adorned with a flipped triangular symbol, sits at the extreme right next to the volume-up button.

  • However, this button is far more versatile, handling multiple functions such as playing, pausing, skipping audio tracks, and pairing with a smartphone or tablet for streaming music.

An intriguing aspect is the ability to double-tap to advance to the next song, although it’s curious that it cannot skip to the previous track.

It increases the volume level of the speaker’s audio output.

To adjust to the maximum, you simply press and hold it for a few seconds until it emits a chiming sound, signifying that the peak has been reached.
