The Vizio V Series 2.1 Sound Bar is a 2.1 setup with a dedicated subwoofer. It has a boomy sound profile that's well-suited to listening to bass-heavy music and action-packed TV shows. There's even an HDMI ARC port and a dedicated AUX port for connecting to voice assistant speakers. This bar can get pretty loud, but there's a bit of distortion at max volume. However, as a 2.1 setup, it downmixes surround content into stereo, and it doesn't support Atmos content. That said, it has a few EQ presets and a virtual surround mode, so you have some ability to customize its sound.

Our Verdict

7.0
Mixed Usage 

The Vizio V21-H8 is decent for mixed usage. On its 'Music' preset, this soundbar has a bass-heavy sound profile that adds extra boom to your audio. Vocals and lead instruments are reproduced clearly, and you can use its bass and treble adjustments to customize its sound. However, there's no Atmos support, and its surround performance is poor.

Pros
  • Gets loud.
  • Four EQ presets.
Cons
  • Doesn't support Atmos content.
  • Some distortion at max volume.
7.7
Dialogue/TV Shows 

The Vizio V21-H8 is good for dialogue-centric content like TV shows. It can reproduce voices clearly and accurately, and there's even a dialogue enhancement mode to make them more clear and crisp. However, due to its 2.1 setup, it has a phantom center, so voices aren't as accurately localized to a pinpoint location in the soundstage.

Pros
  • Gets loud.
  • Dialogue enhancement feature.
Cons
  • Some distortion at max volume.
7.4
Music 

The Vizio V21-H8 is satisfactory for music. On its default 'Music' preset, it has a boomy sound profile with extra punch and warmth in the bass range. Vocals and lead instruments are reproduced clearly, though this may be overwhelming for some listeners. Fortunately, there are bass and treble adjustments to help you customize its sound to your liking.

Pros
  • Four EQ presets.
Cons
  • Some distortion at max volume.
6.3
Movies 

The Vizio V21-H8 is passable for movies. This 2.1 setup has to downmix surround content into stereo to play it, which doesn't sound very immersive. Also, it doesn't support Atmos content. That said, it can get pretty loud, and it can reproduce dialogue quite clearly. The extra boom in the bass helps accentuate action-packed scenes, too.

Pros
  • Gets loud.
Cons
  • Doesn't support Atmos content.

    Differences Between Sizes And Variants

    The Vizio V21 soundbar comes in one color variant: Black. You can see the label for the model we tested here. There's also another variant of this soundbar, the Vizio V21-H8R, which has a similar look but comes with a screen on the remote.

    If you come across any other variants of this soundbar, let us know in the discussion section below so we can update our review.

    Popular Soundbar Comparisons

    The Vizio V21 soundbar is a 2.1 setup from Vizio's 2020 lineup. It's fairly straightforward, but it does have a few sound enhancement features, including four EQ presets and a designated AUX port for a voice assistant speaker. However, unlike some of the more premium soundbars we've tested, it doesn't support Dolby Atmos content, and you can only stream audio to the bar via Bluetooth.

    If you're looking for more soundbars, check out our recommendations for the best soundbars under $200, the best soundbars for dialogue, and the best soundbars under $300.

    Vizio M Series M21d-H8R

    The Vizio V Series V21-H8 is a better soundbar than the Vizio M-Series M21d-H8R. The V Series has a more neutral sound profile and a better soundstage performance. Also, it gets louder with much less compression at max volume. However, the M-Series is better-built, and it has a Full HDMI In port that supports 4k passthrough.

    Hisense HS2100

    The Hisense HS2100 and the Vizio V Series V21-H8 are both 2.1 bars with similar strengths. They're similarly sized, and both are decently well-built, with support for Dolby Digital and DTS but not Dolby Atmos. They both have warm default sound profiles that still reproduce dialogue and speech clearly, and both get loud enough to fill a living room with sound. The Vizio has less compression at max volume and allows you to adjust the subwoofer level. Otherwise, both soundbars offer an extremely similar performance, though the Hisense retails for less.

    Vizio V Series V51-H6

    The Vizio V Series V51-H6 is a better soundbar than the Vizio V Series V21-H8. The V51-H6 is a 5.1 setup that has dedicated satellite speakers, unlike the 2.1 V21-H8. It also has a better-balanced, more neutral sound profile. 

    Samsung HW-T450

    The Vizio V Series V21-H8 is a somewhat better overall soundbar than the Samsung HW-T450. The Vizio is better-built, and it comes with more connectivity options, including an HDMI ARC port and two AUX ports. It also has more sound enhancement features, including dialogue enhancement. That said, the Samsung has less compression at max volume, so it may be better suited for use during loud parties.

    The Vizio V21-H8 is a plain, simple soundbar. The top, back, and underside of the bar are black plastic, and there's fabric covering the front and the sides.

    The subwoofer is made of melamine with a plastic top, and it sits on four plastic pegs. There's a port on the back side, along with a pairing button.

    If you're looking for a setup with dedicated satellite speakers, check out the Vizio V Series V51-H6.

    Dimensions - Bar
    Width36.0" (91.5 cm)
    Height2.3" (5.8 cm)
    Depth3.2" (8.2 cm)

    The Vizio V21 soundbar is long, but it should still fit between the legs of most 55 inch TVs. Also, it isn't very tall, so it shouldn't block your TV screen unless your TV sits flush against your table.

    Dimensions - Subwoofer
    Width8.3" (21.2 cm)
    Height9.8" (25.0 cm)
    Depth8.3" (21.2 cm)

    The subwoofer is about the same width as an average desktop PC, but unlike many other soundbars with an external subwoofer such as the TCL Alto 6+, it's also fairly short. It connects wirelessly to the bar, so you can place it anywhere in your room as long as it can connect to a power source.

    Build Quality

    The Vizio V21-H8 has a decent build quality. The sides of the subwoofer are made of melamine, while the top is made of plastic. The bar itself is mostly made of plastic, which feels solid and durable. However, the fabric covering the front and sides of the bar seems like it could get dirty or rip easily. For a better-built soundbar, check out the Vizio M-Series M21d-H8R or the Samsung HW-A550.

    The Vizio V21 has a good stereo frequency response. On its 'Music' preset, it has a boomy sound profile due to the overemphasized bass range. Vocals and lead instruments are reproduced clearly and accurately, but you notice extra punch and warmth in your audio, which can be overwhelming for some users. There are also some bass and treble adjustments to help you customize its sound.

    With calibration, the Vizio V Series V21-H8 has a good stereo frequency response. It has a more neutral, balanced sound profile with its bass set to '-4'. There's still a little extra punch in the bass range, though. That said, it's suitable for listening to lots of different types of audio content.

    Stereo Soundstage

    Crosstalk Error
    2.99 dB

    The Vizio V21 has a satisfactory stereo soundstage. It sounds about as wide as the bar itself, but the bar doesn't have any tricks to make it sound wider than that. Its focus is okay, so objects like voices and instruments seem to come from an accurate, pinpoint location rather than a general area.

    This soundbar has good stereo dynamics. It can get louder than the Vizio V Series V21x-J8, but there's a bit of compression when you play it at max volume, especially in the bass range, so audio reproduction isn't as clear.

    This soundbar has a good stereo total harmonic distortion performance. At normal listening volumes, the bar produces a clean and pure sound. There's a bit of a jump in THD at max volume, but it may not be audible with real-life content.

    The Vizio V21-H8 has an acceptable center channel performance. Due to its 2.1 configuration, it has to use its left and right channels to simulate a phantom center. This doesn't sound as clear or as real as discrete localization, though. You may notice that voices aren't accurately anchored to a pinpoint location in the soundstage.

    This soundbar has a poor surrounds performance. It has to downmix surround content into stereo, which doesn't sound as clear and accurate as a home theater setup. Surround objects seem like they're coming from in front of you rather than all around you.

You can customize its sound using its bass and treble adjustments as well as its EQ presets, including 'Movie', 'Music', 'Dialogue', and 'Game'. You can even use the TVOL button on the remote to activate the night mode feature when watching TV at night. However, it lacks premium sound enhancement features, such as a graphic EQ and room correction.

As a result, it's a solid choice for watching videos and movies. Some apps and TVs compensate for latency differently, so your real-world experience can vary.
