There are, of course, contentious points that some people consider to be drawbacks, such as two inputs working in parallel. If we make the assumption that you have one input connected to a computer, then in the second input you connect the phone through a wire, and when the phone is turned off, the wire can flicker, and you need to remove it from the speakers. This is one of the controversial points. The loudness of the music played directly from the phone is average; but, if you connect the phone to a mixer, sound system, or pre-amplifier, the volume and quality will be significantly improved.
