What kind of stereo is better for square dancing? I chose it for my mom, do you have any recommendations?

I think the song Lang sound is good ah! Before I bought a to my mom, every night to see her pull out of square dancing, speakers can also connect Bluetooth, nothing to put home, I will also use the phone Bluetooth connect speakers to listen to music, the sound quality of the speaker is really good, basically no noise, there is bass, nothing I will take it to listen to the music, the range of ability is also very strong, can be used for a long time, the volume can be turned on to a very large coverage is very far ~ the appearance of the value of the also good. Cool, overall quite recommendable ~
