The Soundwaver is thought to myself for hotels. There I would need to carry big boxes. The minimum size of Soundwaver convinced me. On many documents, he works without loss of function (window, table, wood paneling). What he has to strengths in the bass range, seems to be missing him in the heights. This is not too flashy (here rather four stars) in music. But with voice output (Höhrbuch, learning videos, Youtube, etc) but tiring for the ear. For party a recommendation. The couple worked for me with Windows Phone, Android and I-Phone. Even PC and laptop worked fine. If the pairing is not possible, you can use the included audio cable. The battery consumption was pleasantly low, charging rarely required. Total for music recommendation.
