    Small and Convenient
    I bought two of them and they seem to be working properly. They're quite smaller than expected, but that's a good thing. Only works if plugged in and can be connected by Bluetooth if the Jack socket is plugged in. The quality of sound is quite good and clear. Overall I am happy with my purchase, and I recommend it.
