The speaker has arrived fully charged at us and was able to be tested. It has an on-off switch, a volume control and a small lamp that indicates the Bluetooth connection. After an hour of listening pleasure, the battery was still full. But the display is also a small flaw, because only when the battery drops below 10%, the lights begin to flash.
Practically, the additional benefit that you can recharge his phone on speaker.
After pressing the Einknopfes the lamp will light up, the speaker is willing to take a connection. With the Sony Z2 connection was found quickly and without problems. We have played only once a song with a lot of bass. We were thrilled. The sound is full and very soft. The bass did not buzz. The sound is on both sides equally well, and is thus distributed very well in the room. The volume has a large range of very soft to really (for me personally) very noisy because the bass is then also feel very strong.
The phone volume can be easily controlled, as well as with the Speaker, I can make the phone silent;) The entire unit can be transported easily with the shoulder strap. The grip comes across as high, so I have no fear that the Geras could solve it.
What extremely striking is the weight. Already in the box I was wondering what it is that hard. For a portable speaker that is really a bit heavier than other models.
From the sound and the quality of her, this speaker really deserves the full 5 stars.
