I was looking for a great sound bar to go with the new 50 inch LED tv I’d purchased. Prices for stereo surround systems can run from a few hundred up into the thousands and I personally wasn’t looking to spend that much. I wanted something that was better than my tv’s speakers without the price of a premium system. I read a LOT of reviews before deciding on this new VIZIO sound bar. Amazon was offering an extra $30 off the normal price for Prime members and I couldn’t beat $148 for this system anywhere. This sound gets great reviews from a lot of techies and I can honestly say that it’s a great system. It’s not just a great sound bar for the money. Instead, this sound bar beats other costing WAY more than this. It has a solid construction, a wireless bluetooth subwoofer and a remote control. To test this sound bar, I played lots of movies (like Godzilla, Transformers and anything else with lots of high pulsing sound) and there was no distortion whatsoever. The sound is crisp and clear and it’s so much easier to make out what actors are saying when they tend to mumble. Recently I had a guy over who works as an eletronics installer setting up home theaters for people. He was so impressed with this sound bar that he said he’d make it a point to pick one up. He mentioned that he’s installed sound bars for other people from all the big brand names and most of those systems didn’t sound as good as my VIZIO. If you want a great sound bar and not pay and arm and a leg for it, get this system. It’s easy to set up and you’ll love it!

Just got this VIZIO SB3821 Sound Bar few days ago. It only took me an hour or so to install and hook up to my VIZIO 42″ HDTV I have hanging on the wall. The sound is really awesome! Hard to imagine this robust sound is coming from a speaker bar this size. The wireless Subwoofer really hits some deep lows…puts in a nice background bass sound to my movies. VIZIO hit a home-run with this set up! Would recommend this to my friend.

Advice for idiots!

This took us about 2 hours to set up, because we’re idiots. Once we realized the hole where the cable goes in the TV has a little door in it, I would say 5 minutes. The hardest part was getting into the packaging (which is good for protecting the sound bar) and the clean up. It sounds so good! We have a 5 year old 55″ Panosonic Viera Plasma and the sound has always sucked, but it has a great picture. This was an inexpensive way to remedy that! Love it!

It just works – without any quirks.

I love this thing. Sounds good but I am no audiophile. What I really like is the functionality. All my universal remotes work fine with it. It turns off automatically BUT all you have to do is hit the volume button on any of the remotes and it turns back on. Easy as can be. The last one I had was a pain because you HAD you use the remote to do anything and universal remotes would not work well. Let me clarify though, I use the universal remotes to change the TV volume, and that still turns the sound bar back on – and it works well adjusting the volume with the TV. The only time I need the actual remote is to use another input (I have 2 TVs hooked up). If you do not have the remote you can easily change it on the sound bar itself (which is the feature my last sound bar lacked. It just works without you having to think about it, which is how it should be. Also has a built in compressor type feature that keeps commercials from blasting you out of the room. This might be the single best feature ever invented.

The woofer makes the experience.

Debated on whether to just get the sound bar or to add the woofer. The sound is much richer and more real life with that woof. Hubby cranks it up so high the dog won’t stay in the room when there’s a movie running. Poor poodle! Thats what you get for having great hearing.

Great speaker! Easy to hookup, even for my girlfriend!

Got for girlfriend’s Christmas present. I usually hookup electronics things for her but I was surprised to find out she did it herself! She said it was easy to hookup. Sound is really impressive from this little thing! be sure you turn the tv volume off through the tv menu or turn it all the way down when you are using the soundbar.

works great

Originally tried to buy this from VIZIO, but their website was having issues, so I bought it from Amazon. A week after I got the one from Amazon, I got the one directly from VIZIO! Apparently the site still processed the order when it was ‘down’, and I didn’t see the order because the email got entered wrong. VIZIO Customer service was great and fixed the double delivery and removed the extra charge.

Totally worth it!

WOW. Get this. Just get this. Vizio nailed it with these sound bars. Let me put it this way. $3000 Bose sound bar system at Costco (yes, $3K!) sounded pretty much like this. I would say the Vizio was 80%-90% of that of the Bose and for sure sounded better than the other Costco options. I went online and found this for $20 less than Costco. The difference is that the Costco one supported some built in streaming where as this you need to tether your phone via BT. No biggie.
