As can be read on other reviews, the size / quality of his report is quite breathtaking. The level reached is exceptional when it is connected to a portable PC, which is not the case on a handheld device such as a phone. The battery actually holds well the burden is announced. I even convinced colleagues blown away by this little thing.
In short a very good deal, although the stereo naturally disappears. With two balls can recreate the stereo effect but it will tinker oneself cable (1 male jack stereo female jack mono + 2)
