The sound is good for a speaker of this price, perfect for watching a movie without headphones, or listening to music but not too loud (it saturates quickly).
The body of the enclosure is made of aluminum, it changes the plastic which is generally used for small speakers, and it does not weigh heavier.
One regret: there is no microphone ... with a microphone, that would be the ideal tool to transform any tablet portable video conferencing tool.
