This is really amazing speakers...small in size but thier sound is very loud and crispy...i love it...also built quality is awesome...very easy to connect just plug the USB in power source and the jack in mobile/laptop and it will start working... value for money product..

First i was confused because it has 1 usb and 1 audio jack but after reading manual i got to know that AUX is for sound output and USB is for powering the Speakers. With laptop we need to connect both and no external power is required. With mobile, Aud cable of speaker to mobile and USB cable of speaker to either USB adapter or power bank. The speaker comes with a connected cable with a split wire one for aux and the other for USB. Hope this provides enough clarification to those who wants ...

Replaced product works awesome and performing excellent. Amazing sound from this little device.
Go for it Guys.

I bet you can't find something better and beautiful than this...Volume level is too good..also its bass is moderate as all speakers have..for a single room it is good...i bought this for my laptop because my laptop has very low sound...i am happy with the purchase..
