It is very portable also.the Bluetooth functionality is awesome.the sound is superb and bass is excellent.i am very happy with my JBL Go as the name suggests Go it means we can take it anywhere.it can also be used as a loudspeaker to talk someone during call.the voice is very clear.If u want to buy u can blindly pick it up from any online website.
