The Vizio V Series 5.1 Soundbar is a simple soundbar. It's mostly plastic, with a thin fabric fitted around the front and the sides. Like the Vizio V Series V51-H6, the control buttons are on top of the bar.
The sub is mostly melamine and sits on four plastic pegs with rubber grips. There's a port on the back, and the speaker is underneath.
The satellites have a similar design to those of the Vizio V Series V51-H6. They're mostly plastic, and there's fabric on the front and the sides. They don't have a power cable, so you only need to wire them to the sub to get them to work.
The Vizio V Series 5.1 Soundbar isn't very wide, though it may not fit between the legs of a 55" TV stand. Fortunately, it isn't very tall, so it shouldn't block your TV screen unless your TV sits flush on the table.
The sub is a bit smaller than the sub for the Vizio V Series V51-H6. It's shorter in height than the average desktop PC, so you should have lots of flexibility when placing it in your setup.
The satellites aren't very big. That said, you need to wire them to the subwoofer to get them to work, which may limit where you place them in your setup.

The Vizio V Series 5.1 Soundbar has a decent build quality. The bar and the satellites are mostly matte-textured plastic, which feels solid and durable. The subwoofer is melamine. However, the fabric covering the front and sides of the bar and satellites seems like it could rip or get dirty easily.

With calibration, the Vizio V Series 5.1 Soundbar has a good stereo frequency response.

The Vizio V Series 5.1 Soundbar has a decent stereo soundstage performance. The soundstage is perceived to be a little bit wider than the bar itself, though it doesn't have any tricks to make it seem wider than that. Also, its focus is decent. Sound objects like voices and instruments seem to come from a pinpoint location most of the time, though they may jump to a more general area sometimes.

It comes with two discrete satellite speakers, so surround objects like voices are clearly and accurately represented in the sound image. Audio seems like it's coming from all around you, rather than just from speakers placed in front of you. That said, the frequency response is quite bass-heavy, so your audio content may be boomy or muddy. If you want a soundbar with a better surrounds performance, check out the Vizio M Series M51ax-J6.
The Vizio V Series 5.1 Soundbar has a decent selection of sound enhancement features. You can customize its sound to your liking using the bass and treble adjustments as well as its EQ presets: 'Direct', 'Game', 'Movie', and 'Music'. You can also set its 'Surround' feature to 'On', 'Off', 'Front', and 'Dual' for a more immersive sound. However, it doesn't come with a room correction feature, so it may sound a bit different depending on the room you're listening in.
The Vizio V Series 5.1 Soundbar comes with some physical inputs. There's an AUX port, which is handy if you want to wire older devices to the bar to playback audio. However, it lacks a Full HDMI In port, so you can't use it as a hub between different devices. We don't consider it to have a true HDMI Out port since it lacks a Full HDMI In, and you can't plug in two HDMI devices at the same time.

You can wirelessly stream audio from mobile devices like your phone to the bar via Bluetooth.

The Vizio V Series 5.1 Soundbar doesn't have a display, though it does have a series of vertical lights on the left side that flash depending on the settings you adjust. Also, when you select one of the EQ presets, there's some audio feedback.
On top of the bar, there are physical controls that let you power the bar on/off, change the input, activate Bluetooth pairing mode, and adjust the volume.
The remote is fairly simple and lets you control the bar's settings. However, it isn't a universal remote, so you can't use it to control your TV.
The Vizio V Series 5.1 Soundbar doesn't have built-in voice assistant support. However, there's an AUX In port on the bar that lets you plug in a voice assistant device like an Amazon Echo. We don't consider this built-in support since you need to purchase a third-party device to get it to work.
The Vizio V Series 5.1 Soundbar has an eco-power mode that powers down the bar after a period of inactivity. You can enable this feature by pressing and holding the power and volume buttons for five seconds. It also supports HDMI CEC, so you can use your TV remote to control some of its basic functions.
