Well, going for the price but better!

Sound / Sound: In my layman's point of view the sound boxing great, the music is also good at high volume, no noise, not shrieks. The bass is okay, only the extra-adjustable 3D stereo mode is not convincing, I hear little difference. Too bad!

Optics: The brushed, golden shimmering aluminum looks great and also the shape is simple but not boring!
Weight: pretty heavy and unwieldy (metal and triangular shape ..) - when using the speaker only at home that should not be a big problem.

Connection: the position of the pin terminal is rather suboptimal because it is located on top and looks like the position not just 'comfortable' for the cable. Just as the USB port, but both wawr well constructionally otherwise solvable.
The Bluetooth connection to the smartphone works flawlessly and very fast!

Battery Performance: keeps the preset 8-10 hours definitely, but I hear but not consistently at the loudest volume.

More: The on / off button is not well designed, it is a small pin to one switches back and forth. Should have you done differently.
Nice bonus would be for example an announcement or indication of the battery level.

Conclusion:
Portable is the speaker, but he looks good and is highly recommended for the price. At the sound's not to complain, there are only a few little things (jack, battery level) that are missing for 5 *.

Update:
After (only) one month use is the battery performance rapidly dropped (charges longer than he is running)! The cables are very loose and not hold properly, besides, I can not load the same time on a laptop and listening to music, the boxes (failure: loud beeps, etc.).
Unfortunately goes back!
