Much I have not expected but as I unpacked this ball I thought only "Oh no, what have you done?, This part can no reasonable sound come out to the box is just way too small." Much too small, it meets well as to the displayed images see the ball a lot bigger than it actually is, the ball reached nowhere near the size of a tennis ball, it is really tiny but chic and particularly elegant, it still looks, scores since the box in any case. Okay I thought, try and if it is not good to me, I can still send it back - so the box once fully charged via USB because the box is in the empty state and has little power, while charging lights up an orange warning light the goes out when the box is fully charged. When the box was fully charged, I have once registered on my Xperia Z as a new device, went super fast by the hand, and then I have the same time tried if it works on NFC - all I can say perfectly, keeping the! phone briefly on the box, and shortly afterwards a signal sounds and the box is now connected to the phone and the fun can begin. For once I have of course looked like the box gets in music, so I turned up (I put the box on maximum volume, even as you get a signal if the highest volume is reached) and have subsequently via mobile phone still set to maximum volume and I really thought struck by lightning how loud the box is let alone how clear and brilliant sound is, with such a result, I had never expected to be unpacked and at this point I can only say, let yourself not by the few negative reviews have fun in this "baby" perish. Next, I wanted to test the distance from when the box in contact with my phone loses, so I went into the kitchen, nothing, I went into the hallway, nothing, I went into the bedroom but distant, nothing that box loses no area contact with the phone and I was speechless again. So for the last test, I asked a buddy he might me but please call briefly said - done, I had my cell phone lying on the desk, the box was or is in my living backplane and I lay on the couch and have five minutes phoned my buddy, eventually I asked him whether he was anything noted what he said what I mean and I said if something sounds distorted or if I have abortions in the line let alone whether he understands me well and he just said "No. , all the best, why? ". That showed me that not even my conversation participants noted that I'm comfortable on the couch and my phone is at the desk, I would say more than just the technology enthusiastic!. Zuguter last I still have the connection attempts via Bluetooth namely with two devices, even it works perfectly and within a few seconds the box was found and coupled via Bluetooth, separating the compound so flash on the box itself has approximately 10 minutes blue Bluetooth light indicates that a the box looking device and is ready for coupling, gets the box within 10 minutes no signal, it switches itself off the. I can only say this little thing it has a sly old ears, operates more than just reliable and really is a true and especially loud sound sensation, of course, producing a box no bass sweeps it a ears off, so something should be clear but apparently not quite as many reviews I can just only laugh, I wonder how high expectations from customers are partially recognized, I'm just very lucky and can the Wireless Speaker at 101% recommend, a big thanks to Sony , That's how it should be!.
