Great Home Theater Sound Bar

Customer has been confirmed to have purchased the item from Walmart.

I recently purchased a Vizio 55" E series TV and as an added compliment I purchased the 40 in. Vizio soundbar (recommended for the bigger TV's 40 inch and up. I was easy to set up with just a couple connections to make between the sound bar and the TV. I spent more time prepping the area where I wanted to set it up and with the wireless sub woofer this is a breeze compared to other home theater systems with multiple speakers. The surround sound in this bar beats any home theater setups I've had before. I find myself turning because the sounds at times seem like they are coming either from behind me or it will sound like it's coming from right next to me. I never had sound so real as with this set up. I figured it would be a good match purchasing the same brand as the TV and I was right. I highly recommend this sound system. For a 2.1 system it has so far exceeded my expectations. The box that it's packaged in could be a little easier to open. I have had a 37" Vizio TV for over a year and the 55" E series pictured below the picture quality is awesome and far exceeds the quality and clarity of even my 37" that I have in my bedroom which also serves as my computer monitor as well. I highly recommend Vizio products to anyone looking to buy a TV or sound system or both. You won't be dsappointed.

Finally, I can add a better audio experience to go with my TV. Setup was a breeze. There was a small hiss when I first put it together but after messing with the settings a bit and finding the right level to go with the TV, it went away. Listening to music in the living room is a lot more enjoyable, TV shows sound crisp, and I'm not constantly turning the volume up and down between scenes in a movie. I'm glad I bought this sound bar. Be careful if ordering this online, or calling the store to ask if it's in stock. This sound bar has a cross reference UPC with the Vizio VSB212. I purchased this online and did store pickup. Didn't realize the difference til I got home. Had to drive to a couple different stores to exchange for the correct one. Other than that, I am really happy with this purchase.

Doesn't come with an optical audio cable like a lot of other brands do. The analog did not work with our TV so we had to purchase the dolby optical cable. Once we did that, it worked fine. Its overall a very good value. It seems to work as well as some models that are 3 times the price.

I have my 55" plasma on a turntable. The sound bar mounts right on the turntable with no tools. The woofer (wireless) is in a corner. Very easy to install. Only negative is that there is now 1 more remote to use. We have Direct TV and use the Direct TV remote to turn on and off the TV as well as the Direct TV receiver. We now have to use the sound bar remote for the volume.

Customer has been confirmed to have purchased the item from Walmart.

Purchased online for pickup at store. Purchased this sound bar to match our 60" Visio TV. Price was the best. Set up was easy. Bar sounded fine. Subwoofer had static and crackled, could barely hear any sound. Thought it had a loose connection. Called Visio technical assistance. Apparently the person who took our call was a pass-through person who had to put me on hold for incredibly long times to contact someone else. I could hear a radio station in the background. The person could not even repeat the problem correctly. If I gave the serial #123456 she would repeat 72869?..seriously and it got worse. I was on the phone so long my phone battery was getting ready to shut the phone down. Frustrated I got a case # and terminated the call telling her that the assistance was brutal and it should not have been. Disappointed with the tech assist we took the bar back for exchange but there were none available at any Walmart store so we got a refund and bought another product. Customer service at Walmart was off the chart wonderful.
