if you want to listen to music during an outing, barbecue, beach, mountains that whatnot, this small bluetooth stereo line input stuff for your mp3 mobile phone solar charger plus extra will make you happy. Its smallness is a quality but forget the deep bass and (very) high volume (especially outdoors). For the atmosphere and look will be the game. Battery life seems more than enough after a first test of several hours. Only regret: no cover delivered.
