The sound is good, but not overwhelming. You can get the Roku wireless speakers and/or subwoofer that can connect to this wirelessly and get a better surround sound experience. The only real issue I have had is that when I switch to the Blu-Ray input, the soundbar will turn on the player, and then the inputs will jump between the one the Blu-Ray player is plugged into and the one the soundbar is plugged into, and keep jumping between the disc player and the Roku screen. Turning the TV off and back on stops it, but it is irritating. It is definitely an upgrade over the sound that comes out of the TV speakers, but it is not as good as an expensive home-theater setup with a 7.1 Dolby Atmos setup, but it is also a fraction of the cost even if you shell out for the wireless speakers and subwoofer.
