Short answer: the Yamaha True X Bar 50A. It ranks #7 of 16 soundbars with a subwoofer by sound quality, rated 3.5/5, at $199.99; the Sony HT-S400 ranks #12, rated 3.4/5, and costs $258, so there is little reason to consider the other one.
What the Yamaha True X Bar 50A does well: The bar and its wireless sub throw a broad, well-defined soundstage for movies, and Expert Reviews praised how articulate the sub sounds. It streams over Wi-Fi as well as Bluetooth, which the Sony HT-S400 cannot. The catch: Overhead effects are modest, and music sounds flat compared with movie playback.
Why pick the Sony HT-S400: The HT-S400 pairs a slim bar with a wireless subwoofer, so movies get real low end without wires across the room. The tradeoff: It has no Atmos or DTS:X and only HDMI ARC, so lossless and height formats are out.
Buy the Yamaha True X Bar 50A. It is rated higher for sound quality than the Sony HT-S400 and costs less, so only choose the other one for a particular feature it does better.
