These small "howler ball" has far exceeded my expectations. The sound is also at full volume and full bass not a bit distorted. The only drawback would be maybe that when you drive the volume and the bass to the limit, the small "howler ball" so so start with hop that no longer sounds beautiful music by the vibration noise. But you can also use a soft surface which dampens the vibrations and the music can sound much more bearable. The processing of the material is of high quality. It offers several connection options - in addition For example, who is not sufficiently long, the short phone cable, which is still a second, longer cable available, which incidentally has a USB port for charging the X-mini II and a second jack. Now to the battery life. I have the device for a week in daily use at full volume and the battery does not make long limp :) Personally I recommend the X-mini II on!
Small, handy, great sound, long battery life, coupled to his "brothers and sisters"
