Compare Soundbars Side by Side

The channel number describes how many discrete audio drivers or speaker groups the soundbar uses. A 2.0 bar has left and right channels only. A 2.1 adds a subwoofer, a 3.1 adds a center channel for clearer dialogue, and so on. More channels generally means more directional audio, though room size and listening position also affect how much difference you will actually notice.

Optical handles standard stereo and basic Dolby Digital 5.1, which covers most TV audio. HDMI ARC adds two-way control so your TV remote can adjust soundbar volume, and eARC supports uncompressed formats like Dolby TrueHD and DTS-HD Master Audio that optical cannot carry. If you stream a lot of 4K content through your TV apps and want the best possible audio, eARC is worth prioritizing.

For a room in the 150 to 300 square foot range, most 100 to 150 watt soundbars are plenty loud at normal listening levels. Larger open-plan spaces benefit from 200 watts or more, especially if the bar has to compete with ambient noise. Rated wattage is a useful comparison point, but sensitivity and driver quality affect real-world loudness too, so use power as a guide rather than the only deciding factor.

Not all soundbars ship with wall-mount hardware or have keyhole slots on the back. The mounting column in this comparison flags which models support wall installation. Even when wall mounting is supported, you may need to buy a separate bracket, so check the product listing before you commit. Also verify the bar's depth against your TV's wall-mount protrusion so the two do not interfere.

Manufacturers do not always publish every spec in a consistent format, and some figures simply are not available in the product data we collect. When a value is missing it means the manufacturer has not disclosed it, not that the feature is absent. If a particular spec is critical to your decision, check the brand's official product page or the listing on Amazon for the most complete details.
