Conclusion: the UE Boom Box cuts sound from by far the worst. By default, the term bass is a foreign word, and bass boost mode (adjustable via the smartphone app) sounding bass tones artificially and dull. Since then also does not help that she was the loudest box compared. Anyone planning to set fire to a short audio cable will also be annoyed that purpose, the box has to be put down the box is unstable and the all-round cover is vertical rather than horizontal. With a long cable, you can just turn the box of course.
A potentially decisive argument for the UE Boom is the 360 ° coverage of the speaker. Who often listening to music outdoors and moves here is the quickly appreciate. For this purpose, however, in my opinion, worth the Fugoo Sport, which in addition to better sound at significantly longer runtime and outdoor properties (protection against water, dust, snow, etc., various brackets and remote control functions). The premium over the UE boom is almost negligible there already.
