Short answer: a tie on sound quality, though neither ranks well in its class. Both are rated 2.9/5 (#24 and #25 of 27 all-in-one soundbars) at nearly the same price ($99.99 vs $97.99), so choose on features and fit. Both are rated below 3.0/5 among the 27 all-in-one soundbars, so if sound quality matters, consider the Hisense A620 instead, ranked #21 at $119.99.
Why pick the Amazon Fire TV Soundbar: The Fire TV Soundbar is a compact, easy upgrade for a smaller TV, with clear dialogue and a Virtual:X mode that spreads sound wider than the bar. The catch: Bass is light and vague, so movies lack impact, and it turns harsh when pushed loud.
What the Samsung HW-B400F does well: The HW-B400F has a fairly flat, even tuning that keeps voices natural, and in The Hook Up’s budget shootout it placed ahead of the Amazon Fire TV Soundbar, Roku Streambar SE and Sony HT-S100F. Watch for: There is no real bass below about 70 Hz, so movies lack impact, and budget bars with a subwoofer such as the Saiyin SBP sound much fuller.
Buy the Amazon Fire TV Soundbar or the Samsung HW-B400F on features: they are rated the same for sound quality at close to the same price.
