Absolutely fantastic! I was quite reluctant to buy early, fearing that the power is too low. But nevertheless, I got solved, since it was the only portable speaker quality at an affordable taken (the following as the Bose Soundlink begin to 300). Well the power is anything but weak, whether on battery or cable (a slight increase wired) exceptional enough for a device of this size. The quality is very good, with all frequencies that stand out smoothly. With a very interesting value for money, I highly advise you.
