I had a chance to test and compare two models: Vizio M21d-H8 vs Sonos Arc and this review should help people who are looking for a good soundbar. The Vizio M21d-H8 was rated 5, while the Sonos Arc has a rating 7. The soundbars are equipped with a different number of buttons, power, volume down, volume up, source, Bluetooth for the M21d-H8 and volume down, volume up, play/pause, microphone for the Arc.
Each of the models under consideration has active amplification type. A built-in subwoofer is available only in the Vizio M21d-H8. Audio features and specs of considered models we rated 5 out of 10 in our ranking. The Arc can play audio from Spotify.
Wireless Internet connection is realized only in the Arc. Soundbars from this comparison have Bluetooth support. There are 1/1 HDMI inputs/outputs in the Vizio M21d-H8 versus 1/0 HDMIs in the Sonos Arc. As in the M21d-H8, so in the Arc there is the HDMI Audio Return Channel (ARC). We rated the connectivity of the M21d-H8 at 6 out of 10, while the Arc was rated 7/10.
The manufacturer of the Arc provides a device control application. The soundbars in this review are equipped with a microphone. The models under consideration cannot become part of a multiroom system.
Dolby Atmos audio decoder is onboard the Arc. Devices from this comparison cannot process surround sound due to lack of DTS:X. The M21d-H8 was rated 5/10, while the Arc received a mark of 4/10 for multichannel surround.
