Video on Amazon.com Watch In this video you will see a test of this Bluetooth speaker that comes in total with a good feel, a decent value and an upgradeable but good acoustics. The instrument is operated via push buttons on the base, the Bluetooth contact is established easily and is stable. I have a range of 10 meters outdoors and 6 meters through a wall measured and was satisfied. The Bluetooth speaker also functions as a hands-free device if you have paired the phone via Bluetooth - the funktinoiert far as problems, but the built-in microphone is not a high-priced, so you close off sien needs, so that you will understand. The battery when fully charged for about 5 hours, but that is of course highly dependent on the volume that you select. For a price of less than 20 euros, I can recommend no better Bluetooth speaker you at least currently.
