l would like to share my experience after comparing and testing two soundbars – Definitive Technology Mythos SSA-50 vs VIZIO SB4451-C0. The Definitive Technology Mythos SSA-50 was rated 6, while the VIZIO SB4451-C0 has a rating 7.2.

A built-in subwoofer is available only in the Definitive Technology Mythos SSA-50. Rate 6 out of 10 received the Definitive Technology Mythos SSA-50 for audio features and specs, but the VIZIO SB4451-C0 received 8 out of 10. The SB4451-C0 can play audio from Spotify.
Wireless Internet connection is realized only in the SB4451-C0. Bluetooth support integrated in the SB4451-C0. The HDMI Audio Return Channel (ARC) is implemented only in the SB4451-C0. We rated the connectivity of the Mythos SSA-50 at 6 out of 10, while the SB4451-C0 was rated 8/10.
The manufacturer of the SB4451-C0 provides a device control application. Soundbars in this review are not equipped with a microphone. The VIZIO SB4451-C0 may become part of a multiroom system.
Dolby Atmos audio decoder support is not implemented in either the Mythos SSA-50 or SB4451-C0. Devices from this comparison cannot process surround sound due to lack of DTS:X.
