excellent clear sound not distorted in high volume, battery acceptable duration, high volume between 6 and 7 hours at medium volume between 8 and 9 hours

there are things that were needed as a port for a micro or usb, only a micro defect a sound that emits sometimes an interruption but of a second, these last days that I have used it has not been presented, I give it a ten for sound duration and design of the product I loved totally satisfied, I have not tested its impermeability but it shows the good material, very happy with the purchase more than 4 months of use, the interior mode, sharp bass, good sound and the external mode the bass are reduced considerably, but without affecting the sound quality, understandable by the excellent outdoor sound expansion product I'm not complaining.

Volume is sufficient to fill a mid sized room w/ great sound.

Love my speaker so far, sound is as promised and price is a steal

For the size of the speaker I thought it was going to have better quality sound.

Great sound and bass

Has a nice clear bass and overall sound with all genre of music

Unbelievable sound from such a small speaker.

The sound is great in the mode that has extra bass

Great sound and loudness for small device
