l would like to share my experience after comparing and testing two soundbars – Vizio M21d-H8 vs Klipsch Cinema 400. The Vizio M21d-H8 was rated 5, while the Klipsch Cinema 400 has a rating 4.6.
Each of the models under consideration has active amplification type. By the number of channels, the devices do not differ. 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.

Both models do not have a wireless Wi-Fi interface. 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 Klipsch Cinema 400. As in the M21d-H8, so in the Cinema 400 there is the HDMI Audio Return Channel (ARC). We rated the connectivity of the M21d-H8 at 6 out of 10, while the Cinema 400 was rated 8/10. None of these soundbars can be controlled using the app. The Vizio M21d-H8 equipped with a microphone. The models under consideration cannot become part of a multiroom system.
