Not what I expected
I was expecting better from this. Not much bass at all and sound quality is not the best. Bought one from other brand (S__Y) which is of similar size and price but beats it in every aspect. Disappointed, especially considering its price.

Ultimate portable sound!
Love it so much! After my son brought me my own I ended up buying one as a gift for a friend who kept borrowing mine they loved it so much. So great to take anywhere for music on the go!
