So I have to say the speaker is truly amazing. I'm not a professional in the area but I think the quality is great! Great sound, great volume and easy to join. No password / PIN needed. Bluetooth on, a speaker and the device connection and you're done! That's it! Even a small bag for the box is included, which I find very convenient because they may be just once stuck in a backpack without this being scratched. The only thing that surprised me (maybe I's also have only read) it is not a plug here. This gives only the USB cable, but actually when everyone has in turn considered logically yes at least one such adapter, thanks to iPhone and Co and who is not well, the few euros you can also apply yet. Therefore, there also no star deduction. The unit is super packed! NO senseless, giant, supplied welded packaging which can not be opened without violence, but made of cardboard and easy to open!
