Due to the many good reviews, I decided for the RS170 system and must say it was a more than good decision; there is no noise, the sound quality on our Panasonic plasma is truly outstanding, thanks to bass boost (you actually hear) and the virtual surround sound (of course, is not a true surround, but also a "spatial" sound enhancement) but with a true surround system is of course not comparable.
The wireless connection is working with us absolutely superb, but I do not change the rooms, I'm sitting here in the living room only, as there are no problems, after switching on the transmitter and then turn on the receiver, it takes only seconds until the connection is.
For music fans, I would not recommend this phone, I hear z. B. a lot of prog rock with very complex arrangements and many instruments, this can sound a bit left to be desired (as mentioned in other reviews), because I for Music, however, have cable headphone I give the RS170 five stars - for film and television.
