## Questions & Answers

**Q: Does an optical cable come with the package?**
A: Related question:  Does it come with two optical cables or only one?  Is a single optical cable sufficient to connect both the soundbar and subwoofer to the television?  (I have an older flatscreen TV that doesn't even have a USB port.  I'm trying to figure out if I can connect this system or not).

**Q: Did the sound bar come with hardware to mount it on the wall?**
A: Yes it did.  Very simple to mount on the wall.

**Q: How can you tell if the subwoofer is hooked up and working properly?**
A: Well' this answers my question about watts not posted in specs...Cant even tell subs on or not its a very sad system.

**Q: if i buy this can i purchase other speakers to make it a 5.1 system?**
A: Don't believe you can otherwise they wouldn't be selling the 5.1 system. VIZIO SB3851-C0 38-Inch 5.1 Channel Sound Bar with Wireless Subwoofer and Satellite Speakers

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great product for an awesome price! Buy it!
*by T***Y on May 17, 2019*

Super easy to connect and get working. It was literally plug-n-play. It works with my LG TV & DISH remote without any programming needed. I haven't tried it with bluetooth for music yet.The only comment for TV volume using my DISH remote is that turning the volume down is fine. The TV stays at 0 for volume level. But when I turn the volume back up, it turns the TV volume up and if it goes loud enough for the TV, you can hear from both sound sources (bar & TV) and it's like an annoying stereo sound. So I'm using the bar remote to turn volume up. It might just be a setting I don't know yet, but thought I'd mention. Not a complaint.The sound is great. The bass is great. Connectivity couldn't be easier!I am using the digital optical cable with my TV.I previously purchased a $380 Samsung sound bar that I returned. The sound was better on my TV than that bar. This Vizio bar with subwoofer is way better than the expensive one.Update: I found the setting on my TV to have the sound come only from the optical cable device (bar). So now no matter which remote I use: DISH, LG TV remote or the Vizio remote - sound only changes on the bar. The TV sound stays null.Also, I didn't see it in the instructions, but if you pause what is on the tv, the sound bar will eventually shut off. Not sure the timeframe yet before it auto shuts off. Then you have to use the sound bar remote and press the volume up to get it back. It comes back on to the level you had it. Wish this setting was adjustable. I've seen it in other soundbars, too.I am still loving this. I've had the bass all the way up and music playing and you can feel the air "vibrate". Its great!

### ⭐⭐⭐⭐⭐ Excellent for the price, after a few tweaks
*by S***S on December 8, 2015*

--- UPDATE ---I have seen more and more reviews lately complaining about fluctuating volume on the newer Vizio soundbar systems. I don't know if I'm just lucky, or if there's something about my physical setup that is different, but I have NOT noticed any fluctuating volume with my system. I have tried bluetooth music from my phone (testing multiple genres), different TV sources (all passed through the optical port), switched from PCM to bitstream TV audio output and back, at high volumes and low, with different bass/treble settings, and still can't find an instance where the volume noticeably fluctuates at all. This is all with the TruVolume setting turned off. YMMV. If you have problems with your system, I suggest returning through Amazon rather than dealing with Vizio customer service, just because Amazon has a relatively generous return policy for defective items, including prepaid shipping. I honestly have no experience with Vizio customer service because I have not had any issues so far, but from what I hear it's not always a fun time.--- / ---I have to admit I was pleasantly surprised with this soundbar. I was worried at first that the 2015 model might not be as good as the highly reviewed 2013 model, but now I don't see how a 2.1 system of this size (and price) could be any better. I am not necessarily an audiophile, but I am a musician and have quite a bit of experience with sound mixing and equalization.I don't usually do this, but I wanted to address/counter another review on this item. The reviewer complained about the reviews being mixed up with the previous version, and the treble being too high on this new system. Well, the reviews are no longer mixed, and while the treble was indeed a bit high out of the box (and as CNET's review of the similar 5.1 system -- the SB4051 -- found, the bass was also too strong at the default setting, depending on your source), this system has easy adjustments for bass and treble settings for that very reason. I found that turning both down a bit and boosting the over all volume brought out some of the missing mid-range just fine. Also, the setting for virtual surround sound should be turned off if you are still hearing too much treble. This setting apparently just boosts the highs to make the sound more spacious and raise the perceived sound stage, giving an artificial surround sound feel. It sounds cool, but might not be the best choice for everyone. After tweaking a bit, I found a happy medium mix for movies/shows, live OTA broadcasts, and music alike. Vocals are now very clear and quite natural sounding to my ear.Sure, the frequency response is still not perfect. For instance, some low tones really resonate, while some sound a bit flat. This partially has to do with subwoofer placement and the type/size of room you are in, but it is also just because this is not a super high-end system. You should not expect this to compete quality-wise with really good (and large) floorstanding speakers and receiver combo that costs over a grand. However, I believe this 2.1 system is the perfect choice for at least 75 percent of people who need a sound system for their TV. It is inexpensive, compact, convenient, flexible, and has enough features (the bluetooth worked flawlessly for me) and settings to keep most people perfectly happy. The sound is surprisingly full and loud when you crank it, more than enough to blast out an average living room, and having the dedicated subwoofer really puts it on another level from the soundbars with "built-in" subs. The fact that the sub is wireless makes it a complete no-brainer to choose this over a 2.0 system, because you don't even have to run that extra cable, so you can put a sub almost anywhere in the room (especially nice if your TV is wall-mounted). Just don't forget to make sure it's powered on and paired (should come pre-paired). Also, the fact that it comes with both RCA and optical cables is a nice bonus. I did notice that the optical connection had a higher fidelity sound than the RCA when connected to my TV, thought most people probably couldn't tell the difference.If there is one quirk with this system I don't care for, it's the input selector. All you get is two LEDs out of a string running vertically on the left side of the bar to denote which input is currently being used, so you have to memorize from the quick start manual which input corresponds to which two LEDs. Assuming most people are only going to use one or two inputs (I only use optical from my TV and bluetooth) anyways, I don't consider this to be a serious enough flaw to dock a star.All told, considering the price (under $150), this system provides great value and more than acceptable quality, and I have no regrets about buying it.

### ⭐⭐⭐⭐⭐ Excellent sound quality with no distortion!
*by M***E on June 29, 2015*

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!
