In total good!

War (something so bring a benefit such is?) On the small device a little surprised. But this little thing brings its performance. But one should remember where the keys or controls are small- -really before handling. If in the end anyway only the Laufstäretaste on the side. The play and start / stop of music files are also the entire front.
Among the speakers: I immediately took that from me, because the supplied brought not even approach a single bass.
Inconceivable that that should be Sony.
Bluetooth works great. Transmission even go through walls (you never need though, as the device is indeed attached to clothing). The device is also a breeze. Is recognized by the phone immediately and one must not enter any Coodes.
Were it not for the weak earphones gäbs 5 star :-)
