The Mini Soundbar was purchased for a tinny sounding Kitchen TV as a support. The part is well finished looks chic. If you (like us) has the TV on the wall, you have to design a bracket because there is no wall brackets. The sound is gehäuße- and moderate price absolutely ok. It does not scratch, but the sound is quite clear over. Since the TV has no EQ, the soundbar was hung for testing at a home facility and it came out a little bass. With us the Soundbar via the USB port of the TV works. How's that for other brands, I do not know (Telefunken 22 inches). The "Volume up / down keys" subjectively bring no change in volume - is also not necessary since it is also on the FB the TV. Who simply etc. better sound on the go, third TV investigated here MMN absolutely right!
