The sound is really amazing for this price with these small dimensions. What the X-Mini makes it a pocket portable speaker, but nothing more. I use it with an mp3 player (iPod) to listen to audio books in the car (My car radio does not have a USB input). The linguistic play is very good.
The only negative point: The rubbery coating is already chipped at the corners (already noticed when unpacking) and eventually the actual plastic housing will only remain, which in reality lies beneath.
So why now only 4 points?
Meanwhile, I have me even the more expensive RAIKKO XL Vacuum gained Speaker, actually because of the optics. The is a little flatter, but edgy but roughly the same size, but has (unfortunately) no integrated audio connection cable as the x-mini, for a more beautiful (better to design matching) power button and the finish quality is better.
Now comes the main point: the sound is much better! I could only do not believe, because the technology is probably the same. But if I umstecke the x-mini to the RAIKKO XL Vacuum Speaker, receives the sound (at the same volume) significantly more body and also the bass and treble sound solid and balanced. OK, this is then probably the price difference, but really worth it. The RAIKKO XL Vacuum Speaker then gets 5 stars due to the really smooth sound.
