I am amazed by the quality of sound for such a small device!
The bass is present, the sound is "hot" and not at all metal and "flashy" as on some competing models. It is very close to the mini Bose or Jawbone ... but the price is less.
The finish is excellent, fingers a little mark on the black part, but it's his only negative!
The configuration with the phone is made in seconds.
Well it must be a fault:
the model had received a pb on two touch keys. Product returned and replaced immediately by Amazon!
