Its a Multipurpose mic with a blutooth speaker, aux meemory card and many otger functions. Few flaws 1. Needs to be on charging if you want to use . 2. For speaker you can use upto 70 percentage of volume. Above 70 percent volume it doesn't work properly. But till 70 percent its great. 3. The singing mode does not work properly. Apart from this u can use it as a speaker and can sing songs a little bit. Blutooth connectivity is also very good. Negotiable. No coins .
