After 60 sec. Test I have the part sent back immediately. The sound is distorted much too high and light, there is no bass. At low volume bearable but not at LOUD. For the price unacceptable. The appearance and the 'hand feeling' let the box appear wertig, equipping of settings and functions is managed. Please test the business which headphones or speakers for 150 euros give, and then compares this with Soundbox, only a sufficiently minus from me.
