works well as a small mobile box in quieter environments / in the near field. For my taste, the box sounds a bit dull, but rather affects only look at the film and can be the playback device simply compensated for music playback over a eq. because the bluetooth transmission takes a bit of time, the film look better on laptop cables to use box, because the sound via Bluetooth lagging half a second behind the picture here. Basically, the box is very robust, relatively light, the Bluetooth connection is cool and the battery lasts a long time.
