For the otherwise still many possibilities of sufficient capacity battery, the relatively low weight (about 500 g) and of course the wireless Bluetooth connection worry. In stationary operation, you can connect alternatively with a 3.5mm jack cable, which I think leads to a small improvement in quality. The battery makes me so far a very good impression and has now held by several times in excess of 8 hours.
The housing like and ensures a solid and clean impression processed. The rubberised exterior touches his well and provides a good grip.
I have no use for the hands-free device or NFC. Both have a short test works fine, but is otherwise not used by me.
From the sound forth this little box can not keep up with full-blown HiFi components, of course. Judging by the size and the price (had Sony's SRS-X2 ergattert for just under 85 euros) but the two 34mm speakers deliver clear treble and rich bass. This is maintained over almost the entire volume range. Only at maximum volume to show minimal distortion, which can be eliminated quickly with a reduction in volume but. Otherwise, the volume is sufficient to fill a 20 sqm room appealing. Personally I use the box for small presentations, listen to music or movies in a small circle. In noisy environments Sony's SRS-X2, however, quickly reach their limits and for party-like situations is such a device due to the concept anyway not suitable.
According to Sony, the maximum performance in battery mode to reduce indeed, purely subjective, I have noticed it but still nothing.
In direct comparison with Logitech UE Boom (standing tube) Sony's SRS-X2 falls sonically somewhat. This can be seen next to the subjectively better overall impression especially in distortion-free maximum volume. Also, the spill-resistant housing and the opportunity to be coupled two devices together features that are missing from the Sony solution. But convinced Sony SRS-X2 with a great price-performance ratio that the missing features in most cases more than compensates.
