I bought one of these mainly as portable speakers having charged it I tried it with iphone 5s Samsung Galaxy S3 & Ipod classic.
The sound is good from all devices considering the size of the speakers and if you can play with the equalizer settings the sound becomes amazing from something this size even from the Ipod. Tick the box for the main reason for purchase good small speaker system just remember they are not ghetto blaster standard but they are great for their size and you can set your own tones with your device settings.
Now for a suprise I found myself out and without much charge in my phone plugging the charging cable in I expected a quick boost enough to make a call (despite the claims) but found they're true you get a decent charge on the Samsung Galaxy S3 point I start this review 19% battery its now 35% using this gadget it is that good.
So if you want to have a device that one way plugged in you can listen with friends or by yourselves to music plug in the other way will charge your device and thats just a little bigger than a large cigar tube so easily fits in your pocket or bag yo can't go wrong with this gadget in my view
Happy listening and Charge!
