The speaker is really great - I did not think that you can get as much bass out of there. For people with perfect pitch this ball is not really suitable, but certainly not well thought. The speaker will be easily found by the cell phone. When you turn it cracks easily and he rushes a bit when no music is playing. This is negligible in the price but in my opinion. Otherwise, the small part is fine to also go to share his music with others fairly reasonable. My daughter had the Assmann DA-10286 Digitus pumping bass Bluetooth speakers on a school trip and was with the red "bauble" high demand ..; o)
