2.1

The Vizio V21-H8 is a 2.1 soundbar 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 are 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

6.7 Mixed Usage

The Vizio V21-H8 is fair for mixed usage. This 2.1 soundbar has a bass-heavy sound profile that adds an extra boom and punch to your favorite songs. Its balanced mid-range keeps dialogue and vocals present in the mix, and there's even a dialogue enhancement feature to help make voices sound clear and present. However, it downmixes surround content into stereo, and it doesn't support Dolby Atmos content, so it won't provide a very immersive movie-watching experience.

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

The Vizio V21-H8 is decent for dialogue-heavy content like TV shows. It has a balanced mid-range, so voices sound clear and present in the mix. The bar can get loud, and there's also a 'Dialogue' EQ preset that acts as a dialogue enhancement feature. You can even stream podcasts and audiobooks to the bar from your phone wirelessly via Bluetooth. However, this 2.1 soundbar doesn't have a dedicated center channel, and it doesn't support other connectivity options like Wi-Fi or Chromecast.

Pros
  • Gets loud.
  • Dialogue enhancement feature.
Cons
  • Some distortion at max volume.
  • Doesn't support Wi-Fi or Chromecast connectivity.
7.2 Music

The Vizio V21-H8 is satisfactory for music. Its default sound profile is a bit bass-heavy, making it well-suited for listening to bass-heavy genres like EDM and hip-hop. It also comes with four EQ presets and bass and treble adjustments to help you customize the sound to your liking. It can get loud, but there's a bit of distortion when you play it at max volume.

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

The Vizio V21-H8 is mediocre for movies. This soundbar can get loud, and its boomy sound profile adds an extra punch to action-packed scenes and movie scores. However, it downmixes surround content into stereo, which doesn't provide a very immersive listening experience. It also doesn't support Dolby Atmos content, which may be disappointing for some listeners.

Pros
  • Gets loud.
Cons
  • Doesn't support Atmos content.
  • Some distortion at max volume.
  • 6.7 Mixed Usage
  • 7.0 Dialogue/TV Shows
  • 7.2 Music

The Vizio V21-H8 is an entry-level soundbar from Vizio's 2020 lineup. It's a 2.1 system with a wireless subwoofer, and it comes with more features than the 2019 Vizio SB2020n-G6. Its main competitors are the Sony HT-S200F, the Sony HT-S350, and the Samsung HW-T450.

Design
Design
Style - Bar

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

Design
Style - Subwoofer

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.

There aren't any satellites in this setup. If you're looking for a setup with dedicated satellite speakers, check out the Vizio V Series V51-H6.

Dimensions - Bar
Bar Width 36.0" (91.5 cm)
Bar Height 2.3" (5.8 cm)
Bar Depth 3.2" (8.2 cm)

The Vizio V21-H8 is long, but it should still fit between the legs of most 55" TVs. Also, it isn't very tall, so it shouldn't block your TV screen unless your TV sits flush against your table.

Design
Dimensions - Subwoofer
Sub Width 8.3" (21.2 cm)
Sub Height 9.8" (25.0 cm)
Sub Depth 8.3" (21.2 cm)

The subwoofer is about the same width as an average desktop PC, but 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.

The Vizio V21-H8R has a decent stereo frequency response. It has a boomy, bass-heavy sound profile, making it suitable for listening to bass-heavy genres like EDM and hip-hop. Its mid-range is quite balanced, so vocals and dialogue are clear and present. There are four EQ presets available: 'Movie', 'Game', 'Music', and 'Dialogue'. We tested this soundbar using the default 'Music' preset.

The Vizio V21-H8R 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.

The Vizio V21-H8 has good stereo dynamics. It can get loud, but there's a bit of compression when you play it at max volume, especially in the bass range.

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 alright center performance. This 2.1 soundbar doesn't have a dedicated center speaker. It uses its left and right speakers to create a sound in the center, but this can sound a bit more diffused than a bar with a dedicated center channel. That said, it has a balanced mid-range, so voices and dialogue still sound pretty clear and accurate.

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.

Compared to other soundbars

The Vizio V21-H8R is a 2.1 soundbar 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.

Polk Audio SIGNA S2

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.

Samsung HW-T550

The Samsung HW-T550 is a better 2.1 soundbar than the Vizio V Series V21-H8. The Samsung is better-built, and it has a more neutral, less boomy sound profile. It also comes with a graphic EQ so you can customize its sound, and a Full HDMI In port so you can use it as a hub between your devices. That said, the Vizio has less distortion when it's played at max volume, so it may be a better option for use at loud parties.

Vizio SB36512-F6

The Vizio SB36512-F6 is a better soundbar than the Vizio V Series V21-H8. The 5.1.2 SB36512-F6 has a better-balanced sound profile that's suited for an even wider array of audio content. It also has discrete surround speakers, and it supports Atmos content, unlike the 2.1 V Series. It also more connectivity options and is compatible with more wireless playback options, like Chromecast and Wi-Fi. It can also be controlled via its companion app. That said, the V Series comes with a dialogue enhancement feature, which the SB36512-F6 lacks.

The Vizio V Series V21-H8 is a better overall soundbar than the Sony HT-S350. The Vizio has a better-balanced sound profile with a lower-extended bass than the Sony, and it also has more sound enhancement features thanks to its bass and treble adjustments. The Vizio also comes with AUX ports, and it supports DTS content, unlike the Sony. However, the Sony is better-built and seems a bit more durable.

Sony HT-S200F

The Vizio has a dedicated subwoofer, unlike the Sony, so it has a more extended bass. It also has more sound enhancement features. However, the Sony has less compression at max volume, so it's better-suited for use in loud parties.

Vizio V Series V51-H6
