Slight noise from the speaker when playing extreme music, such as DJ or high-pitch songs, at maximum volume is due to the limitations of sound effect tuning. The speaker's tuning strategy aims to balance various factors like loudness, bass, vocals, and dynamics to provide an overall high-quality audio experience. However, achieving perfect clarity at maximum volume, especially with extreme audio sources, can be challenging. This results in some unavoidable background noise. To mitigate this, it's recommended to lower the volume by 1-2 notches, which can help reduce the noise and improve the listening experience.
