All devices were quite Powerful for their size, which is very surprised me. The worst of the anchor has very clear cut, since he had little depth and the sound was shrill. At worst, I do not mean that the unit has been bad because of this size, the sound was satisfactory.
The other three units were very similar. Ups and downs were very balanced. From the sound in the central regions Wavemaster MOBI-2 has in my opinion the best performers. However, the Rokono B10 had a bit more depth and thus a bit bass-heavy, which I personally like better, even if the sound is not quite as clear as the Wavemaster. CSL is the sound similar to Rokono, but he can not keep up with the volume test.
I opted for the Rokono, even if there has been a neck and neck race between Wavemaster and Rokono. This is for everyone a matter of taste, but there is a big difference in sound between the two devices is not.
But one thing bothers me, so I have to deduct a star. Both the master and the Wave Rokono a signal and a subsequent voice sounds when you turn on the device. The voice is set to full volume, therefore quite loud and totally unnecessary. Unfortunately, you can not turn off the and forced it on and connect to hear them.
Schade, a slight pleasant sound when switching would have been sufficient (see my CSL model).
Nevertheless, a buy recommendation from my side, because the sound for the size and the price is really good
