The box is designed to be very minimalist.
Technically, it has rear for loading an aux input with 3.5 mm jack and a mini-USB jack. For the operation (top), only the on / off switch, a volume up / down rocker and the pairing button are available.
Facilities also include a microphone, as well as on the box calls can be made. Comes in handy for Telcos or family conferences.
The appearance is sleek monochrome, but the plastic casing does not look cheap.
From the sound of her, lacking in any case the bass. For the size, the unit is, however, every effort and you can partly the bass. Hear, but guessed well in any case. And the high places could be better, and it comes but also on the source depends. But you should not fix the standards of a HiFi system.
The data transmission via Bluetoooth always worked well (max. Range 4m) and I could see no Höreinbußen (compared to the Aux input with the same device and song).
Very well mastered the Airwave volume. You can see the dB (A) violently turn upwards, without the distortions occur. Thus, one thus goes down well against pure conversations and the sound is not lost on a limb in the garden.
From the battery performance here, I am also satisfied. 5 hours' operation, at normal volume, the box held by.
If the sound was a little better, it would have given 5 stars.
