Even though I have not tried it out, which is nevertheless the plan. Music while cycling without headphones. For such a small thing comes as genuine a passable sound out - limiting I have to mention that I do not have perfect pitch and I am perhaps somewhat satisfied with where a musical gourmet gets Puking just. It can be. But must not, The cute little box can be nice sound for a room, of course, not the case that a wegfetzen ears, but for ne musical accompaniment of a full-size space, it is sufficient absolutely. The Böxchen is easy to stow and the connecting cable to the music playback device under is ... um ... built on such a roll-up automatic, as in these Metermaßteilen, where you just have to push a button and the extended measure quick in seconds back into the case. Since it runs on batteries, it is necessary to sometimes charge, the charging cable is included, but is only suitable for charging on the PC or laptop, if you have a plug adapter, it comes naturally that way. A small light indicates when the part is in operation ... when it loads and when it's done. LED goodness that's now quite uncomplicated. The rubberised outer shell, it is also still pretty robust ... good Leeistungsverhältnis and from my side highly recommended.
