In the package you have the HDMI cable for HDMI ARC connections, RCA analog cable, and even Velcro straps to really help secure your installation. The speakers and subwoofers are included with this soundbar, and the manufacturer also makes sure to include the cables needed.


First of all, the design of the Vizio SB3651-E6 is incredibly sleek and stylish. Every detail is kept track of and the black soundbar fits perfectly with your overall interior.

Not only that, but the pretty slim profile also makes it easy to place it anywhere you please with the flexibility to be wall-mounted as well. This characteristic is also shared by other Vizio models.

The placement of the Vizio SB3651-E6 is flexible. You can choose to place it on the entertainment unit, shelf, or on the wall itself. Tabletop or wall placement is recommended for the best angle. Make sure that the placement won’t be met with any obstruction.

Weighing in at only 1.8 kg or 4.6 pounds, this soundbar is easily portable and can be moved around the house if necessary. You have the unique option to connect the soundbar to multiple TV devices and the included speakers and subwoofer are also transportable.

Among the most important things are the setup and usage of the model. The system interface is easy to understand and the setup of this Vizio soundbar takes no time at all. If you have any questions, the user manual included in your purchase has answers to solve any problem you may have.


Perfect Pairing

The Vizio SB3651-E6 soundbar provides perfect pairing with the content onscreen. It allows you to seamlessly immerse yourself in the experience without any hindrance.

Remote Control

Sound bars don’t always come with a TV remote, but this does! The remote for the SB3651-E6 is well-designed and there isn’t much for you to figure out. The black and white contrast makes it easy to read and the little LCD screen will display input settings such as volume.

Google Chromecast

Vizio prides themselves in making their products compatible with this. Once you get the Smartcast app, you can then control the sound from the soundbar and cast it directly off of the soundbar and pair the audio to your VIzio TV. 

Using Vizio Smartcast can substitute the remote if you can’t find the other remote. Use the app to increase the volume, decrease the volume, set a mode, or change a number of settings in the systems as you like. 

Not only that, but you can also name the individual inputs. Our reviews reveal that Google Home can also be used with the app. Though not everyone will always use every feature in the app, it’s still good to know the range of functions one can find in the model.

Surround Sound

This soundbar simulates virtual 5.1 surround sound. You might need to tone it back down a bit with the level of power it can produce, but the true surround sound experience is clear.

Loud sound is nothing without intelligible speech and audio details, which the SB3651-E6 soundbar has as well. The design itself seems almost as if it went through the proper tuning process to ensure clear audio. 

If you’re fine without Dolby Atmos, this sound bar will provide a great movie experience in your living room. In our reviews, the quality is close enough.

Sound Choices

Not only can you experience a full 5.1 surround speakers, but you also have the option to customize the soundbar system depending on the size of the room you are in. Other than the 5.1, you also have 2.1 and 2.0 available if you need to use it in a small room.

This is especially good for those who want to find another way of using the model and improving the overall experience. We like having sound choices because you can decide which is good enough for your personal space.

Satellite Speakers

The satellite speakers may earn a large part in the sound quality provided by this sound bar. The smaller speakers with your purchase package are the ones responsible for producing the medium and high frequencies and helping to catapult the entire system into the next level for audio quality.

5 Channels

The sound bar is configurated to simulate 5.1 surround sound [1], which is the industry standard for room-filling and expansive sound. 5 channels mean there are five points of sound emission from the sound bar itself to give you that home-theater system you want.


It has both analog and digital inputs and connections to make this Vizio sound bar compatible with many devices. All that you need to connect the device to your TV is also included in the box to make setup even easier.

It has the HDMI cable for the HDMI ARC connection as well.

The Bluetooth connection is a luxury that will eliminate unsightly wires. It also allows you to play music with your sound bar and stream it from your mobile device for better quality. So if you want to use your mobile as a way to stream music, you can do so.

Subwoofer Bass

The sound system comes with a wireless subwoofer for those who love deep and thumping bass. When there’s a subwoofer, listening to the lows become much better the first time. You can actually feel the rumble as you play your video or music content and the bass frequency is around 20 Hz. When the subwoofer volume is set to high, get ready for earth-shattering sound with the sub.

Aside from the sub, you can also set up the two rear speakers (left and right). If the sub wasn’t enough, the two back speakers (left and right) will really do the work. Not all products include a subwoofer or back speakers in the setup, but they’re great to have especially if you’re looking for the right surround speakers system.

Apple Music Airplay

Not only is this Vizio soundbar compatible with Chromecast, but it also works well with Apple music airplay. It doesn’t matter if you are an avid Android supporter or die-hard Apple fan, you can get the sound bar to work with both.


Not all new sound bar systems come with Wi-Fi compatibility, but this one does! You can use Wi-Fi for a lot of things, especially if you like playing a range of movies.

Sound Quality

An array of amazing soundbars, including this one from Vizio, offer you up to 101 dB of booming sound that will capture the faintest whispers and the loudest explosions. Even at the highest volume, you will have little to no harmonic distortion. 


Price is always something we look at. The price of the soundbar is also very reasonable considering the ease it provides with Vizio Smartcast plus the excellent sound quality. This soundbar is best used for rooms of any size, whether big or small. The sound is pretty close to higher-end models. In our review, the price for this Vizio soundbar is just right.

Vizio SB3651-E6 Review Conclusion

The Vizio SB3651-E6 provides excellent sound for a very affordable price. Not only that, but it also comes with all the best features and accessories a consumer would want to have to create that perfect home theater surround sound.
