As others have mentioned, the sound quality is pretty lean, and lack of headphone or speaker outputs of connecting additional speakers only via the SCART socket using a special cable is possible. In order, however, the volume is no longer controlled via the remote control. Which probably is common in the current devices.
Also negative I noticed is that the device quite slow turns when changing channels while short is a disturbing noise of itself.
Otherwise, I can associate myself with previous speakers, for the little money you get a total of fairly high-quality product.
