The controls are mounted below the Metallumantelung and are self-explanatory.
Also below the casing there is a USB mini port for charging the box, a slot for a mini SD card,
a microphone, a headphone jack, the on / off switch, a switch to switch between music and radio,
a Play / Pause button and two buttons for the volume and skip tracks or radio station selection.
The charging time was nearly 3 hours and handed for nearly 5 hours of music.
The Bluetooth pairing (HTC, iPad, iMac) is quick and easy.
Coupled I have the speakers with the iPad,
The music volume can be controlled via the volume control on the iPad or on the speakers themselves.
The sound is good and sufficient, so I refer you to this speaker size at this point in my video.
Overall, the excellently processed speakers convinced.
