Style Name: New Sound BarSize Name: 38-Inch with Subwoofer
First, let me set the context for this review. This sound bar is not designed to satisfy the audiophile. It can not compete with a dedicated AV system or a $700 sound bar. With that said, those of you who own the flat and extremely thin LCD/LED TV sets have probably become accustomed to a certain quality of sound emanating from those tiny speakers. You will be astonished the moment you connect this Vizio. First, although it is approximately 38 inches wide, it is less than 4 inches tall and 3 inches deep. For many 40 to 55 inch TVs, this means it will not block the screen if rested on the TV stand in front of the set. While it is still possible this location may interfere with the TV's remote receiver, especially if fixed in the middle (as opposed to the far corner), you may find the clearance between the sound bar and TV sufficient to avoid this difficulty.

Now on to the sound. I have listened to Blu-ray, Pandora and movies from my satellite provider with this unit and must say I am extremely impressed. For movies, dialog is crystal clear. Soundtrack details are excellent but do lean toward the bright side. For certain soundtracks the "True DTS" setting creates amazing separation and surround sound although this will probably be influenced by how far the bar is located from side walls. In one of the sci-fi "space" movies, the sound of the space ship could be heard to soar above the screen and well beyond (both left and right) the physical dimensions of the sound bar. The small but unobtrusive wireless sub woofer (about the weight of a gallon of milk) paired with the bar instantly and while not earth shaking, adds palpable weight to both movies and music. It is not "boomy", even when located in a corner.

I did my research for weeks on what sound bar I should put my money into. After the easy set up I could not be happier with my purchase. I had Sony surround sound before this and this sound bar blows that out of the water. Excellent base and clarity. Some people complained about the bluetooth connection and range but it works perfect. I was able to stay connected in all parts of my house. This has met every one of my expectations.

I bought two of these from Costco for family members for Christmas. They were a great deal and the recipients seem well pleased so far. But I made the purchase after reading these amazon reviews. Only later did I realize that the majority of these reviews are for the much more expensive 5.1 system that includes rear speakers, quite a different product. So just be aware of that as you read through these.

Style Name: New Sound BarSize Name: 38-Inch with Subwoofer
I am reviewing the S3821w-CO 38 inch 2.1 Sound bar (since it seems some of these reviews are mixed together!) I got this item from an after-Christmas sale at Walmart for $150, but I've noticed that if you watch this item in Amazon, you'll catch it at roughly the same price point on occasion. I have a 55-inch Vizio 3d television, and the speakers on the TV are typical for flat screen...decent midrange, but terribly muddy high notes and almost nonexistent bass. After reading reviews on a number of soundbars in the $200 range, I settled on this one because of the favorable reviews, and yes....because it was also on sale. But boy am I glad I did.

First, the pros: This soundbar connects easily to your television and has enough connection options for pretty much any television configuration. I recommend the Digital optical cable (which it comes with!) if your TV has that option. You probably won't get any better quality. But if your set doesn't give you that, you still have "regular" digital, the standard red/white audio, and a 3.5 jack as well.
The sound is absolutely fantastic for the price. Of course there are better systems, but you're not going to find them on a similar budget. I've had full 5.1 channel audio systems at home before, and this 2.1 actually does a very impressive job replicating the full surround you'd get with bigger setups.
After a quick install, I popped in my test blu-ray -- Star Trek VI. Yes, I'm a sci-fi geek. The opening notes of the introduction rumbled through my living room like never before, and the subwoofer performed beautifully when placed behind the viewing couch.

Style Name: New Sound BarSize Name: 38-Inch with Subwoofer
I purchased this unit as a way to get better sound then the integrated speakers on my samsung TV. I wanted something to add a bit more impact and depth but didn't need or want to spend a small fortune. When i picked this unit up I was a bit hesitance and was wondering if it would do the trick. I got it home the setup was very easy the cables and everything you need were included "the optical cable is very short" I had it hooked up and outputting sound in less then 5 mins that's excluding the unboxing time :) But once I got the tv and my smartphone connected to it and was immediately impressed with the sound output. Now this might be because i haven't had a decent sounding setup in some time but i have had plenty in the past never the less im excited once again to watch movies and cant wait till I can test it out on an NFL or boxing match. The Sub is currently only set to half way and it filled the room with more than enough bass. And the clarity was great. So far i have found nothing wrong with this unit and look forward to really giving it a good test in the next few days.
