When you say ordinary amplifier music, you mean the home theater stereo. Generally speaking, the background music is embedded audio, the volume is not too loud, and wireless audio is used in some places, which saves the wiring project. This leads to the lack of sound power and some defects in the internal acoustic design of the sound.

One more thing, background music is usually arranged in a relatively open environment, which is very fatal because it will cause a lot of noise to mix into your ears. None of the sounds you hear are pure tones.

The above is considered from the acoustic point of view. If it's convenient, I recommend background music, because you can hear voices everywhere in the room as long as you turn on your mobile phone and choose music with one button. Unlike the audio-visual studio, you have to debug a series of equipment such as audio to enjoy music. And it has a lot to do with your position (panoramic sound is not considered here).
