for such a small speaker i must admit it produces powerful sounds with its 2x 4 watt speakers,ive found to get the best sound quality from it to have it just below full volume ,i also like the fact that i can use it totally wirelessly due to it having a built in micro sd memory slot giving you the added option of taking it absoloutely anywhere without the need for any other device and even small enough to fit in your pocket
the speaker itself feels extremely well made with the top and bottom being made from a nice thick rubber/silicone coating with a solid mesh frame so if dropped it would take the impact pretty good,each of the control buttons are nice and big so easy to see aswell as being nice and firm when pressed
the other features of the speaker are, its a splashproof design and can play music 1 of 3 ways aswell as having NFC technology with built in handsfree
overall its is a good speaker for the price but doesnt give you the battery life it suggests as i got 12 hours using it at half volume so id give it a 4 star
