I bought the speakers, because I like to go for a long time on the road and in the hotel or outside on good sound of my music could not live without. The purchase was worth almost 100%. The speaker is beautifully packaged and makes appearance to a cool impression. The sound is excellent for size. The tones are clean. Bass comes out, to my mind even very pleasant - not too much, not too little. NFC pairing with Bluetooth work with my Samsung Galaxy Note 4 properly. With my laptop there are from time to time problems with the Bluetooth connection to this unit however. Sometimes the active Bluetooth connection says after 15 minutes connection time-bye, while my laptop (Lenovo Thinkpad T520 with Windows 7 x64) reproduces music. After that I have to build again the connection manually via laptop. But this problem could affect even my laptop, so I want to spread this nothing wrong.
The thing on the device does not satisfy me is the battery life. For me, the speaker holds an average of 3-4 hours at quieter music playback (10-20% volume). For the size of the speakers could offer more. With an external battery, this problem can, however, get a grip.
