I had a chance to test and compare two models: LG S80QY vs VIZIO M512a-H6 and this review should help people who are looking for a good soundbar. The LG S80QY was rated 7.8, while the VIZIO M512a-H6 has a rating 5.6.
Each of the models under consideration has active amplification type. A noticeable difference is the number of channels that S80QY has 3.1.3 and M512a-H6 has 5.1.2. The built-in subwoofer is not implemented in any of these models. An external subwoofer can be connected to any of the units in this comparison. Rate 7 out of 10 received the LG S80QY for audio features and specs, but the VIZIO M512a-H6 received 8 out of 10.
The S80QY can play audio from Spotify.
Wireless Internet connection is realized only in the S80QY. Soundbars from this comparison have Bluetooth support. 1/1 HDMI inputs/outputs are in each of soundbars. As in the S80QY, so in the M512a-H6 there is the HDMI Audio Return Channel (ARC). Connecting devices via USB is possible in both models. The connectivity of each of the models was estimated at 8/10.
None of these soundbars can be controlled using the app. Soundbars in this review are not equipped with a microphone. The models under consideration cannot become part of a multiroom system.
Manufacturers equipped both units with Dolby Atmos audio decoder. Units from this comparison can process surround sound due to DTS:X support. The S80QY was rated 10/10, while the M512a-H6 received a mark of 8/10 for multichannel surround.
