    I picked this up on sale, but even at its regular price, this sound bar is a steal. The sound quality easily meets or beats others twice it's price. I replaced a 12 year old 5.1 receiver with this after mounting my tv on the wall. It fits nicely on the wall just under my 50" TV and looks great. I love the wireless sub, but I'd recommend not placing it too close to your couch, chair, or where ever you plan to sit to watch movies because even with the bass turned down, it can be pretty overpowering. With proper placement of the sub, the whole unit has awesome sound with crystal clear highs and mids and nice full bass. The Bluetooth feature connects nicely to my ipad, phone, and computer for playing music and sounds great with about the same sound quality as pandora or spotify...not quite cd quality, but that's streaming music for for you. All in all, it's no thousand dollar theater system, but for a system under $400 with only two components, this thing is incredible.

    Got this sound bar today as an advance Christmas present from my kids. Paired with a Samsung 55" tv, the set up took less than 10 mins and the sound quality met my expectations. This is an excellent sound bar for the price. It delivers quality audio and enriches the overall watching experience. Pairing devices via bluetooth was seamless and was an added bonus. If you are looking for a starter sound bar without the need to be blasting sound across 3 blocks and waking up the neoghbors, this product is worth considering.

    Great Sound Bar, Too Big To Sit On TV Stand
    4/25/2014

    Customer review by Branshtan

    4.0 stars 4/25/2014 by Branshtan

    This sound bar would look great if you were to mount it on the wall under your flat screen (it is the same length as a 42'). However, if you put this sound bar in front of the TV on a TV stand, it is going to block about 1 inch of the TV. I tried to put something under the TV to lift it higher, which solves the problem of it blocking the screen, but it is still blocking the TV from receiving signal from the remote. Basically, if you want to put this in front of your TV, you will have to raise your TV by about 2.5 inches for everything to work. This unfortunately doesn't work for me ... I have returned it and got a different sound bar that is lower in height. Other than it being too big to put on a TV stand, This Vizio Sound Bar works great. The sound quality is superb and it enhances the movie-watching experience. I have a Vizio TV and I was able to use the TV remote to control the volume of the sound bar. Set up is very easy. You will need an optical audio cable which is not included.

    I have a Vizio 60" and a good living room for acoustics so I got this smaller speaker bar and mounted it on the wall (it is so light it comes with adapters and drywall screws and a template so it took 10 minutes to mount. It sounds great for a 3 channel setup and the tru-surround feature fills the room. Since I own a Vizio TV the remote worked the soundbar except for the bluetooth sync. DRAWBACKS- the sync range is limited to about 20 feet so don't wander to far. Make sure you have an optical or coaxial digital OUTPUT on the TV, that way you dont need to change inputs on the soundbar (very limited connection options. The unit is not expandable to accept rear speakers so if you plan on updating later make an investment in a 6 channel now. There is no display other than a series of lights that alert you to mode and input. And get a quality optical or coax cable for 20 bucks, the one provided is short and cheaply made. Where it counts, in sound quality, this unit works great!

    THIS WAS FOR A XMAS GIFT FOR MY SON, BUT HAD NOT WRAPPED IT YET. WE BOUGHT THE TOP FAMOUS NAME BRAND AND WAS DISAPPOINTED. WE PAID 3X AS MUCH FOR THIS PRODUCT. WE OPENED THE BOX WHICH WAS FOR MY SON AND HOOKED IT UP. WOW! WE WERE PLEASANTLY SURPRISED HOW THIS LESS EXPENSIVE PRODUCT SOUNDED MUCH BETTER. WE ARE KEEPING THIS ONE AND BUYING ANOTHER ONE FOR MY SON. I AM GOING TO RETURN THE MORE EXPENSIVE ONE.

    • A. Screws that attach to the back of the sound bar are included. The brackets that these screws hang in are also included. The screws to attached those brackets to the wall are NOT included in the box. You are on your own for screws/anchors to attach the bracket.
