Great sound
I bought this item just over a year ago and was very pleased with the sound quality and ease of connection, so when I bought another TV this year for my vacation house I purchased another one. Great value and quality. Sound is crisp and clear even when the volume is elevated.

Great sound

I bought this item just over a year ago and was very pleased with the sound quality and ease of connection, so when I bought another TV this year for my vacation house I purchased another one. Great value and quality. Sound is crisp and clear even when the volume is elevated.

Great Sound

I bought the Vizio sound bar system about a month ago. Big difference in sound delivery. Feels as if your in a movie theater. Highly satisfied with this sound bar.

Great Features. Easy to use. Convenience factor.

I had originally two setups. Samsung TV and a sound bar and Vizio TV and Sound Bar. The abilities Vizio has with Chromecast is really amazing. But what made me get a 2nd Vizio TV and Sound Bar setup for the bedroom was the app functions. I can turn off, turn on and raise and the volume from my phone. In a different room. Kids have tv too loud no need yell I simple lower the volume from my office. Great parental controls.

Marvelous Sound

After a lot of time researching which Sound Bar System I should buy I decided to go with this one and WOW WOW WOW, I made the right choice. The sound is way louder than what I was expecting (way more). The Vizio SmartCast app allows you to control all of your settings (Woofer Base, Treble, name, SoundBar name, etc). It's just a wonderful toy to have. The SoundBar is easy to mount, it comes with a mounting plate that you can use as a guide. And yes it's Bluetooth enable so that you can play music via your phone, tablet or computer. It's just a piece or art !!!

Good soundbar and a great price

I bought this soundbar for my wife's parents to hook up to their Vizio TV in the family room. They were really impressed with them improvement in sound over the tv's normal speakers. The additional bass module really gives the sound nice depth and is a great purchase if that's of value to you.

We had a small issue with the sound from the tv coming a half second sooner than the sound from the sound bar. It was easily fixed by going into the menu and turning off the tv's speakers completely.

I was pleasantly surprised that the soundbar, when hooked up via included optical cable, also turns on and off with the tv. There is a lag to it turning off; it takes 5 to 10 minutes. To get it to turn on they have to press volume up or down after turning on the tv, but I was thrilled that they it worked with their dish TV remote and they wouldn't need an additional remote to control the sound.

Finally this was a great purchase for them b/c it was the same brand as their tv and like brands usually cooperate better. It also doesn't have all the extra features, which for them is a huge bonus because they don't love tech and simpler is better. They really did appreciate the improvement in sound. Overall a great purchase.

Excellent sound, difficult to install

Now that we finally have it installed the sound quality is great. It was extremely difficult to install as it needed ethernet cable that was not provided and none of the directions/videos indicated that we would need this. We finally figured it out and like the product.

Works well and easy set-up.

Works well for a TV sound system that is not full surround sound. Smart enough to know that I have turned off the speakers on the TV and then pick up the output signal the TV sends when I change the volume of the TV on Start-up of the TV. This can take a few seconds, but it is worth the wait.

Excellent Sound, Well Built

This sound bar has plenty of sound and great volume. I took 1 star off because the directions were terrible and not easy to understand. After figuring out why the sound did not come on right away, I fooled around with the inputs and it finally came in and worked well. The instructions were NOT good. The sound bar itself is of good quality and has great sound. I suggest anyone to buy this. I got it for about 110 dollars and on sale. Great deal !!!

Great Sound Bar If You Have Patience to Set It Up

There is no real question about what is the best sound bar out there. It is Vizio but I am not sure about the ease of getting the sound bar installed or smart cast activated. It took me close to an hour just to get the smart cast to working. The smart cast is essentially an idea that Vizio has borrowed from SONOS but the main difference is of course that SONOS speakers are far better and getting them installed is childs play. I tried so many options to get the sound bar on the network that when it finally worked, I was not exactly sure what made it work. If you go through the effort of setting it up, you cannot beat the sound quality for the price though.

Great product but arrived damaged

Love the sound bar and the subwoofer but the subwoofer sound is slightly distorted because of the imperfection or damaged spot on the bottom. I didn't know how I could exchange for another considering I bought it online. Any help with this would be greatly appreciated.
