How about the Little Bee k-119 usb wireless amplifier?

This is a wireless portable type, and I feel that the Little Bee amplifier is just like that. If you are doing square dancing or some gatherings, you can still barely use this. As for the sound quality, it can only be said to be average. The most commonly used wireless portable loudspeaker on the market now is the Desheng E17, which comes with a lavalier and handheld microphone. It is also more convenient for teaching square dancing. I suggest you check it out!
