Best speaker of this class

After intensive studies and pre-listening of portable speakers in this class I had originally decided to use the Bose SoundLink Mini. Shortly before buying seemed the JBL batch 2 in the hands and immediately convinced.
- Sonically both quiet as loud properly. More always goes clear of this size, however great, especially in direct comparison to the Bose.
- The bass is really a stunner, especially if the device is facing a wall
- The sound waves are radiated in a much wider angle, as for example when Bose. The Bose sound good only if he can play directly on a horizontally. 30 degree deviation upwards or downwards let the sound quality fall heavily. Unlike here in JBL, which has significantly higher tolerance here.
- The player device may be charged through the speakers simultaneously. Connection via USB socket.
- Pairing via Bluetooth 3.0 works flawlessly.
- Making calls via the loudspeaker is also possible. The caller hears a well.

2 negative things that stood out to me:
- On solid surfaces, the device is good to soft it rolls sometimes away.
- No Cover. Who should the device takes along time to travel like to invest in a bag.

Price / performance for me super, strong buy recommendation.
