These speakers surprised me with the sound quality, they are not jawbone or Bose quality, but still clear sound at full volume.
The instructions say it won't charge smart phones, but the solar panel does charge my 4s (slowly). I do not believe they Are bluetooth, such is the only flaw I can think of for the money.
