VIZIO M-Series 5.1.2 Immersive Sound Bar with Dolby Atmos, DTS:X, Bluetooth, Wireless Subwoofer, Voice Assistant Compatible, Includes Remote Control - M512a-H6

This thing has no business sounding this good, given what it costs. It is a tremendous value for a simple, home theater audio in a box solution. Now the "good for what it costs" part is important. It doesn't break the laws of physics, you can certainly spend more and get more, but the little dedicated subwoofer really does a solid job in compensating for the relatively small speakers in the main unit. It also gets surprisingly loud for its size without introducing meaningful distortion. Are you going to put this thing in a giant, dedicated home theater or a huge great room with a cathedral ceiling and be happy with the results? Probably not. But in a bedroom, an apartment or an average-sized living room or den, this is likely going to give you results you are happy with for both movies and most casual listening. When you give it a workout across a bunch of different genres of music, you find the results vary between adequate and excellent. There are some basic physics reasons behind why you normally need much bigger speakers to get truly excellent high fidelity sound. So occasionally the results are a bit flat and uninspired. But it does a pretty remarkable job for what it cost and how big it is. What you will notice if you listen with a very critical ear is that there is some muddiness in the mid-range and the bass rolls off too early because the little sub runs out of steam, but that almost seems unfair to criticize at this price point. Most people won't even notice any of that. On the other hand, don't get super excited about the strength of the Dolby Atmos effects here. Atmos is designed to create a 3d sound field and place sounds in the physical space around the listener. It is a cool new technology and movies are starting to be mastered in it. Normally that 3d sound effect means you have to have additional channels physically mounted in the ceiling. Like all of these sound bars, it doesn't have actual ceiling speakers and instead has to make do with pointing some speakers up at the ceiling to bounce the sound off the ceiling indirectly. If you stick it in a basically square or rectangle shaped room with an 8 foot ceiling and no obstructions, it does sort of work. But if you have a cathedral ceiling or sloped ceiling or anything other than the basic box shaped room it likely won't do much of anything. On the other hand, the more basic, 5.1 surround sound effects are perfectly adequate, assuming you can place the little rear speakers properly. Installation wasn't hard, although note that there are specific requirements that the system sit in front of and a certain distance below the TV because of the Atmos, up-firing speakers. The rear surrounds connect to the subwoofer with standard speaker wires and the separately powered subwoofer then connects wirelessly to the main unit. The little sub is ported, so it can't be set absolutely flush against a wall. It all came pre-paired up and worked perfectly right out of the box. I have a modern tv, and was able to connect with eARC/HDMI successfully. I also paired my phone to the device using bluetooth and that worked easily too. I can control the volume with both the TV remote and the Apple TV remote control, and so I will almost never need to use the included remote for much of anything beyond initial setup. There is a reason why this unit got such good reviews on the big audio review channels. It really is a good value for the price.

After doing a lot of product hunting, I was really excited about this soundbar. I almost jumped the gun on a few others, but I'm glad I waited for this one. If you're looking for an entry soundbar to go in your family room and don't know what Dolby Atmos is, then I'll be honest: this is not the home theater setup for you. There are plenty of other systems that perform well for hundreds of $ cheaper, including the Vizio V series line of speakers, which you can also get in 5.1. If you have heard of Atmos or want the newest middle-ground speaker, then this is it. Before you click the "Buy Now" button, make sure you are ready to take advantage of Atmos, though. You'll want to make sure your TV supports it (if it has eARC label on an HDMI port, then you're good), the content you're watching supports it, the device you are using supports it, and that all of your settings are correct across the board (for example some TVs disable ARC by default and this should be enabled). If you have all of those things, then this tops it off. The included HDMI cable is ARC so you can use that to connect the soundbar. Make sure you use the port labeled eARC on the soundbar and the TV. HDMI is the best method, you don't want to have to use optical if you don't have to. For my full review: Pros: *All-around sound is great. I've watched only a few hours of various types of shows and it does a good job of handling lots of dialogue, or a sporting event, or a highly dramatic scene. You won't be absolutely blown away, but depending on what you were using before this could be a major game-changer. At the end of the day, it sucks me into the content and that's all I need. *Left and right speakers have PLENTY of cord length. I didn't look into it, but I would guess somewhere between 20 to 25 feet of cable for each side speaker and they connect to the sub which is wireless but obviously needs power. One end of each side cable has an L-shaped plug while the other is straight. Make sure you know which one you want to feed through the tube of a speaker stand before setting up so you know where your cable is going to go. Only the straight plug will fit through most stands. Read the manual for setup, but in case you miss it, the blue plug is the left speaker and the gray plug is the right speaker. The speakers themselves have color-coding on the inside of the ports as well to help. *Soundbar itself is kind of big compared to others but has a pretty low profile which makes it great for fitting right in front of the TV and not being in the way. *Upfiring speakers are much better at providing Atmos sound compared to the digital/"fake" up-firing speakers that I have heard in some other soundbars. *Remote is a nice upgrade with the digital display that makes it easy to change inputs. Cons: *Depending on what content you're watching and if it's in surround sound, I noticed that it can take the speaker about 5-10s for it to start playing a sound while the TV is already playing video. It was also out of sync (ahead) by about half a second, but I corrected this in TV settings by adding delay. *Bluetooth was slow to connect, even slower to start playing music compared to the video as mentioned in the bullet above. Not terrible, but there shouldn't be such a long delay between pressing play and it actually playing music. That's why I give it 4 stars on Bluetooth. Everything else about BT is fine. *EQ and level settings on the remote are... bleh. What's strange is you can go through the levels, like Bass for example, and change it to either + or -. Only once in each direction. And when you hit something like "+" you now have to pick between + or - because there is no way to return it back to neutral for that setting. I wish there were more levels to the levels. I would definitely recommend turning Bass and Height Speakers to +, possibly also turning the side speakers to +. For the weird EQ settings on the remote, I gave it 4 stars on remote. I am personally pairing these speakers with an LG 65NANO85 2021 TV, a Chromecast with Google TV, and tried it with Netflix (Sophie documentary was a dolby atmos title, according to Netflix). If you are using Netflix, you need to be on the premier plan to get Dolby Vision and Dolby Atmos, by the way. I had only planned to watch about 10 minutes at first, but once I sat there, the visuals and the speakers absolutely drew me in and I couldn't stop. Not only did it sound crisp and clear, but I felt like I was in the room. I couldn't really notice the Atmos effect while watching, but it made me feel surrounded and it felt very natural. It was one of the closest feelings I've had to being in a movie theater sound system at home that wasn't some audiophile's home setup. For $500 (It will likely fall to $450 on sales, maybe even a $400 price tag sometime??), I truly believe it is a good value. This is practically the cheapest way to get into true Atmos entertainment right now and I'm definitely happy I did. Since this is a pretty new product at the time of review, I'm hoping others get in on what a great system this is. You're not going to be getting perfect audio and this isn't the top-of-the-line stuff, but I really think this will check a lot of boxes and be a very convenient solution for a lot of people that want to enjoy their shows and movies immersively.

Pros: - Good sound for the price. Bass from the quite small 6" woofer is surprisingly tight and strong...for the size - Decent options for editing sound profiles - Easy to setup and get working Cons: There is basically just one con and many have addressed this in the reviews. Inconsistent operation. - Strange and loud pops, twice, from the soundbar so far - Volume decreased by itself 3 or 4 times, but not in the last couple weeks. - HERE's the BIG ONE: it eventually just stops working altogether. I believe the real fix for it is to pull the power from the soundbar. Many times I've just done everything such as reconnecting cables, restarting the TV and then pulling the power on the soundbar, but my most recent tests seemed to indicate that removing the power from the soundbar is the quickest way to get it back up and running. This is a clear indication that Vizio has an issue somewhere. I've confirmed that it IS on their most recent firmware version so that is not the issue and it obviously was not the fix that many had hoped for. I considered returning it but since we just moved and there has been so much to deal with, I'm just going to place this soundbar on it's own power strip with an on off switch so that I can quickly and easily reset the bar when needed. Summary Most people would not want to have to deal with these kinds of issues with a brand new product so my recommendation is that most buyers stay away from this product. But since the sound quality overall is pretty good, at this point I'm fairly confident that my workaround of power resetting the bar every week or two will be quick and easy and cost effective. I actually had to do this, but less frequently with my old 10" Kliptsch Subwoofer so not a biggie for me. UPDATE I did put the soundbar on its own power strip which is easy to reach yet still hidden. When the soundbar decides to stop working, which these days is about every 2-3 weeks or so, I turn off the power strip for a 1-3 minutes and then power it back up. That gets ts it working again. Also, it's been many months since we've heard any of the odd pops we heard soon after the purchase. So given the price I paid and the pretty good sound out of it and this easy workaround, I upped the rating to 4 stars. Still, shame on Vizio for letting this out without a proper fix.

I've had the SB3651 for a few years and always loved how good it sounds for the price and how easily it works with different TVs (Vizio/Hisense). I have that setup for my lounge surround. It was time to get an upgrade on my Bedroom surround and although the Hisense U8H already has great sound, its hard to beat a dedicated system. I originally purchased a Platin Monaco system that I regretted quite instantly after installation. The sound was no where close to even the TV and the independent speakers, although look cool, they just refused to work well at all. After much trying, I ended up returning it after 2 days and immediately purchased the M512 and boy o boy does it sound amazing. I know it's probably not as good as a 1000$ soundbar system but for the price this punches way above its price tag. The atmos speakers help create this sound cocoon that envelop you in the middle, everything properly sounds like its around you with sounds from top front and behind. The sub is a big upgrade on older models and no matter how loud you get the sound (and it gets very very loud, 15% is quite loud for a bedroom), but no matter how loud you get the sound, it doesnt crackle or lose any quality. Watching atmos content on this is amazing. Highly recommend this. PS I chose this over the M elevate since you get less moving parts (0 vs 2) and the sound is 99% there.

I used to have a bulky onkyo receiver (was top of the line at the time) mated to 5 in-ceiling speakerkraft modules and a subwoofer as my home theatre setup in my previous residence. It sounded phenomenal. But we needed to downgrade and keep things simpler for our new house. Decided to try this Vizio setup to mate to our new 77" LG OLED unit after racking my brain doing extensive soundbar research. Understand that a soundbar will never, ever sound as good as a good, traditional amp/speaker setup. And you can still spend in upwards of $2k for a soundbar combo. But for $3xx-4xx...I don't think this can be touched in terms of features or performance. It is VERY impressive for what it is. Assuming your tv has an existing eARC port, setup is pretty much plug n' play, and you'll be able to control the volume via your TV remote. The soundbar itself emits quite clear dialogue/highs. You can tell it has quite a few speakers integrated (including vertical firing), as the soundstage is 3 dimensional. The bass is DEEP and loud. The subwoofer module itself is wireless and can be placed anywhere in the room, but is recommended in a corner location to enhance the low frequency reverberations. It honestly sounds like an 8 or 10 inch subwoofer. Trust me when I tell you, you will feel the bass at medium to higher volume levels. The rear surround speakers are not wireless and are mated to the subwoofer module. They do provide ample wire for both of these speakers though. My only complaint would be having truly wireless surround speakers, but beggars can't be choosers at this price point. I have a $200 hisense 5.1 dolby atmos soundbar setup...and to be honest the Vizio M-Series blows it out the water in terms of fidelity, especially the higher frequencies. There's levels to audio components, which is only limited by your budget. But from most all the audiophile reviews I've seen, you simply cannot beat this M-series unit in this price range. Oh, and lastly....we have not experienced any sort of lag/delay/synching issues that have been reported by many others with this particular model. However, we don't use it with any external components, either. We exclusively use it with the tv (we use Youtube TV streaming), so you may have a different experience if using in conjunction with a gaming console and/or external media player. This unit is so good, I may end up selling my Hisense and ordering a second one of these for my bedroom.

I have had this soundbar just a little over a year. Since purchasing there have been problems. To start, the soundbar originally had massive sync issues with the television. I have a newer Vizio M-Series TV as well which I purchased a few months prior to the soundbar. My previous soundbar did not have the new HDMI E-ARC feature and it was causing weird behavior with the TV syncing the controls. I purchased this very excited to get ahold of one which would seamlessly communicate with the TV and boy the joke was on me. I had issues where this soundbar wouldn't power on with the tv, an easy enough fix, but then the bar needed an update at one point and the update made the audio never sync automatically with the TV again unless you manually set the input. No big deal, next update fixed this however since the last update the soundbar settings will completely reset themselves every time I turn the TV off and it powers down with it. I lose all my sound settings and have to go and re program them once I notice that the vocals are not as high as they were the previous night. I contacted Vizio multiple times about this issue and every time was told to do an update (when it was on the most updated firmware to begin with) and to factory reset the TV and soundbar. None of these solutions work and I have continued to have issues with it resetting itself again and again since then. When I most recently contacted Vizio Support I was advised because I purchased it from a third party seller (which was the suggested link when I purchased and not really advertised that it wasn't amazon) I now have no warranty and no recourse. Vizio stops updating their products the second they get a year out of production so I can only assume we will never see a fix for this as their last update was done in 2022. This is beyond frustrating and I am now stuck with a half functional soundbar that I can neither return to amazon or get replaced by Vizio. Amazon won't accept a return on the item either at this point so I've attempted to reach out to the seller in question, but I really doubt I'll get anywhere with them either. I would 100% recommend shopping other brands. I have been a very big fan of the Vizio brand for a long time but since getting my most recent TV and Soundbar from them and having nothing but problems, I cannot continue to suggest the brand to anyone in good conscience. Choose someone else who actually stands behind their products and doesn't tell you where to stick it just because the item is over a year old. It seems ridiculous that my TV which is well over a year old continues to have updates but the soundbar is not being kept up to date especially with these major issues. If only we could give 0 star reviews, the hassle this thing has been from the start was not even worth the 1

Perhaps not the best ATMOS system, but it really brings an immersive sound experience at a low price. I'm using this together with an LG C1 OLED. Here's my setup: EARC HDMI connection between the LG and the soundbar, the peripherals (Blu Ray, etc.) plugged into the other HDMIs on the C1. I'm NOT using the second HDMI (passthrough) on the bar. Pros: —Sounds great! Way too loud for my needs, and intense bass. Overkill for my room, but nice to know I've got the power when needed. —Soundbar shows colored LEDs to indicate the audio signal type (green = Atmos) so you never need to wonder if it's getting the right signal input. My fireTV stick has Disney, HBO, Apple, etc. apps and they all automatically output ATMOS to the bar if/when available. —Excellent CEC support! By setting all connected devices to CEC, the remote commands are passed/shared through the connected equipment. I use a FireTV Max stick for almost everything (Live YoutubeTV, streaming apps, etc.) Touching the Fire remote turns on everything, and is able to control the volume on the soundbar as well. I now only use ONE remote for everything! —Alexa! I've tried various ways to incorporate Alexa into my media stack only to find too many "gotyas" and unexpected conflicts. This unit has both bluetooth, and a 3.5mm stereo connection for music input, but it also has a dedicated 3.5mm wired input specifically for an intelligent assistant like Alexa. I have an Echo Dot plugged into this input. When Alexa speaks or plays music, the unit changes the input automatically to allow the signal from the assistant to be heard, when done, it switches back to whatever you were listening to originally. Brilliant! This is the perfect kind of handoff. —Easy to mount! Cons: —YOU MUST DO AN OS UPDATE before you touch anything (It'll wipe out any settings you've made). This bar is not connected to wifi, so it's a manual process requiring a download, a usb stick, and some patience. See the instructions for the bar. —CEC does have some conflicts with my C1 TV, for example, using the voice function on the fireTV remote causes the C1 to change inputs. Not a problem with the bar, but you may encounter CEC issues with your TV especially if it's an older model. —Audio level conflicts can happen between the Alexa and the bar. The total volume output when using an Alexa input is a combination of the volume you set on alexa and the volume you set on the bar. They can easily get wacky if one or both are too high, or too low. I highly recommend this product for "pro-sumers" looking for ATMOS at a bargain price. Be well!

I consider myself technically literate. Finding Atmos content and getting it played through these speakers is incredibly challenging. The only major streaming services that offer Atmos are Netflix and Prime. Both require the ad-free, highest monthly cost subscription. Even if you have them, the content that has Atmos is limited. If you are happy to pay premium subscriptions, you are probably good to pay for a ~$1000 dollar system that will be nicer than this If you aren't willing to pay for those services, you can find a 5.1 system that will probably match this sound quality for ~$200 dollar system I've confirmed on my Xbox one x that the speaker will not receive Atmos when passing through eArc through my Vizio TV I bought in 2018. However, it will receive Atmos if I connect directly to the speaker and pass through video to the TV. It's not a big deal but if you don't have a new TV, and you have multiple devices you stream through (I have an Xbox and Roku), you will only be able to stream Atmos through the device connected directly to the speaker. You'll need to swap cords around to get Atmos out of the second device. The soundbar only has one HDMI in. I have Amazon music which is supposed to have spatial audio. I'm still figuring out how to get it running properly. With how new Atmos is and the limited popularity, getting all the settings set properly on your devices, apps, TV and speaker clearly isn't something that has been prioritized by manufacturers. If it isn't all set correctly, you won't get Atmos. It's more frustrating than it's worth. I'm happy with the sound quality when it's playing 5.1. I won't be returning the system. Hopefully more Atmos content will be made more easily available. However, if I had to make the purchase again, I'd just go with the 5.1
