Overall Review

The ‘VIZIO SB3621ns-H8 36-Inch 2.1 Channel Home Theater Surround Sound Bar’ with Wireless Slim Subwoofer enhances the sound quality of your television.

The wireless thin subwoofer adds booming bass to sports, TV shows, movies, and music, and the soundbar has three total speakers that deliver superb audio performance with dramatic and accurate sound at 100dB.

All you need is an outlet for this adaptable subwoofer, which can be positioned upright to fit discreetly in the corner of the room or laid on its side to slip under your couch.

You’ll get room-filling, floor-to-ceiling virtualized 3D sound with immersive effects like aircraft flying overhead and rain falling from the sky with DTS Virtual:X sound enhancement according to this Vizio SB3621NS H8 review.

For high-quality music streaming, you may use Bluetooth to connect your phone or any compatible Bluetooth device wirelessly to the “VIZIO SB3621ns-H8” 2.1 Sound Bar. With all audio cords included, setting up this home theater is simple and takes only minutes.


The sound of the Vizio SB3621n-E8, which costs $150, defies its small dimensions and low price. Even if it cost twice as much, we’d give this soundbar system top marks. It’s without a doubt the best-sounding inexpensive soundbar we’ve ever heard.

There are no “features” to speak of, save from a wireless subwoofer and Bluetooth, but at this price, you don’t need much more. The Vizio SB3621n-E8 is now one of the best buys in home theater, alongside Google’s Chromecast Audio.

You could even combine the two, connect them to a TCL Roku TV, and you’ve got yourself a $500 wireless streaming AV system according to this Vizio SB3621NS H8 review.

The Vizio V Series 2.1 Sound Bar features a dedicated subwoofer and is a 2.1 soundbar with a dedicated subwoofer. It boasts a boomy sound signature that’s ideal for listening to bass-heavy music and watching action-packed TV episodes.

There’s even a separate AUX port for connecting to voice assistant speakers, as well as an HDMI ARC port. Although this bar may get quite loud, there is some distortion at the maximum level according to this Vizio SB3621NS H8 review.

It does, however, downmix surround content into stereo as a 2.1 setup and does not support Atmos content. It does, however, feature a few EQ settings and a simulated surround mode, so you can tweak the sound.

Out of the Box

The SB3621n-G8 is an upgrade to Vizio’s earlier 36-inch 2.1 bar, which included a larger subwoofer. The bar, a sleek new sub (more on that later), a remote, an instruction manual, and 3.5 mm and optical connections to connect your TV and other devices are all contained in a bright orange package.

There isn’t much to write home about in terms of aesthetics, as there isn’t much to write home about at a lot of bars. The rectangular bar’s elegant silver end caps on each side are a Vizio design hallmark that complements the tiny sub perfectly.

In terms of the sub, Vizio has redesigned its ported sub to be ultra-thin, allowing it to be hidden beneath couches and chairs for maximum rumbling according to this Vizio SB3621NS H8 review.


The SB3621n-ability G8’s to immerse us in the action on-screen impressed us right away. You’ll enjoy great digital sound straight out of the box thanks to DTS and Dolby Digital audio capabilities.
