Strange device... Works as it should, loud and quick to sync with iphone. But it has this weird start up noise...It emits a jarring noise akin to thomas the a toy thomas tank engine playing 3 seconds of electro 80's synth - every time you switch it on!...

These are an awesome little speaker that pack a punch. Super easy to operate. I brought it as a travel buddy for my music in my phone. I work outside and it is perfect as an outside radio. Really handy that you don't need power or batteries and it...
