    Great for the money, sharp design but lack of HDMI connection and inability to get true DTS/digital sound is a disappointment. If I use digital through TV the sound sync is way off. If I select PCM, sound is in sync but I lose DTS signal even using optical cable. I used a coaxial cable directly from 4K Blu-ray player to the soundbar but got no sound. Shame.

    This sound bar totally surprised us. We were blown away by how great it sounds. We had gotten used to the (normal) back-firing speakers on the TV and had *no* idea what we were missing. I’d researched much more expensive bars from other brands, but we could never justify the cost. I heard about Vizio’s Sound Bar on two different podcasts and decided to try it. Very glad we did. Set up took minutes and the wireless subwoofer works like a charm, every time. Highly recommend.

    The sound bar system has been a great addition to the household. The struggle of having to increase/decrease sound volume and adding subtitles are gone. It fills my apartment with brilliant sound. It’s loud enough to make the experience like you are at your own personal movie theatre without disturbing the neighbors. The setup and integration process is simple and seamless. Well worth the price tag for this item.

    The subwoofers small profile allows it to be placed under the couch which gives a pretty dynamic experience, being able to feel the rumble beneath you while watching movies was a nice change of scenery from previous systems I’ve had. The soundbar on the other hand lacks debts in the audio, you really need to have both the soundbar and the subwoofer on simultaneously to achieve dynamic range. Overall a pretty good system for the price

    Easy to install. The sound quality is much better than the speakers in our Roku TV. The basses are low and rumbly but don’t drown out the high end sounds. It’s not audiophile level of good, but my untrained ears can’t tell the difference.
    Definitely recommend. And my kids have already figure out how to use it, so it passes quarantine ease of use test.

    It was rated very high on the tech sites comparing to sound bars that were way more expensive. I’m an audio engineer, and I was very pleased with the sound, not just because it was inexpensive.
    The sub initially was too “woofy” for the person sitting next to it on the couch. Before turning the sub down, turn it where the speaker faces the couch. This worked great and it still sounds just as powerful on the other parts of the room.

    Nice soundbar, took a bit to figure this out, nowhere in the instructions did it tell me to turn off the tv speakers, so I was getting a tin can sound. Finally dawned on me to try, and solved my issues.

    This is a replacement for one we lost while moving. I was very upset when I discovered the bar itself was gone. We bought a competitors’ product, and while they are a very reputable company and their product was good, it still wasn’t as good as this one.

    Great product for the price! We used the model before this for years and loved it. We got many of our friends and family on board with vizio showing our old model off. We bought this new one about a month ago as a replacement after the old one broke (due to a houseguest’s negligence, not any fault of vizio’s) and so far are very happy with it. Looks very sleek, minimalistic and professional. Also, it’s easy to install. The only thing that surprised me was that it didn’t come with screws to mount it, so just be aware you’ll want a few screws, possibly a few anchors if you don’t have wood studs, a leveler, and a drill in order to mount it. Looks awesome in our living room, and the bass is great especially during movies and listening to music.

    I don’t mind that the order was delayed twice for more 2 days as i do not need it the very next day, but once again the box was damaged on another Walmart item, box was ripped, obviously opened and then re-taped again, and most definitely looks like it was used for sure. It was easy to set up and it works okay i guess, but I don’t have any others to really compare it to. My issue is with the repackaged item and selling it as brand new when it can not be that when it was opened and picked up by anyone but the manufacturer and packager. The box was torn, the very tight cardboard packaging was 100% already opened, and then re-taped. So I don’t know if it was only opened up or if it was bought, used, and then returned only to be re-sold to me as brand new. Sell it as used if it is used and not brand new when it ISNT brand new.
