Did the BTM2056 / 12 now for two months in operation. Most important to me is the sound. That is unfortunately very average. I find him to be very flat with little detail faithful. Stereo I will not say anything. Overall, somewhat dull and DBB system too bassy. The equalizer settings to bring as little remedy. At the other most seem to me the settings pop and rock. The others (Classic & Flat) are unusable. In addition, I have noticed that the radiation plays an important role. The more you lower compared to the plant the darker and duller will the sound. Initially the plant was in the kitchen on the refrigerator. There you can but the display does not see and the sound is terribly dull. Now she is at waist height on a wooden cabinet. This improves the sound of something and so the display is recognizable. As a source I use mainly radio and Bluetooth. The signal strength of radio is Mittelmas and Just OK. The signal strength and coverage for Bluetooth is good. The service is OK. The remote control only works if you show exactly on the device! The display is very poor. It is very dark and hardly contains information. All in all, I'm a little disappointed. I paid around 140Euro and it would have expected a little more. When I think what makes the Mobi example of Wavemaster as a simple portable powered speakers for 20 euros to sound, the BTM2056 / 12 is not limited to the amount of time or too expensive.
