    Initial Impresisons, will update.

    The soundbar and rear speakers are really impressive. They were super easy to install, and they come with every cable for what I would think is every possible audio input option a person can realistically want (optical, hdmi arc, aux, rca, etc...). The bass is very good (can easily get way too loud). You may have to change your settings, which I highly recommend you toy around with, this is best done using the vizio smartcast app.My settings go between music and movie EQ mode, where I like as follows:Bass 4.Treble 2.Center 8.Surround volume 12 (this really makes your rear speakers kick in for

    For the price, it is everything I expected

    I read some of the reviews and I saw a lot of good and Bad ones. Now I know you get what you pay for but I got way more out of these speakers than I thought I would be getting.I love coming home from work after a long slow day and just getting in the bed, turn on the blue tooth, and jam out. These have amazing quality sounds for this price, I can control the speaker settings through the remote or my iPhone which I didn’t know before buying, the volume on these can be extreme or if you prefer small volume these will do that just fine while providing the best quality sounds, the only problem I’v

    Good Value

    Full disclosure - I'm Rebecca's dad, not Rebecca, and this is my soundbar.My main entertainment center includes a Denon 5.1 receiver with Bose front speakers, Sony mid & rears, and a Yamaha powered subwoofer. I wanted my other TV to have better sound than the cheesy built-in speakers, but in a simpler and cheaper sound package. After much research, I decided to bet on the Vizio 3651.What's in the box? There's a 36" long soundbar that connects to your TV either via HDMI or an optical cable. There's a wireless powered subwoofer with a 4" speaker. And there are two small surround speakers that co

    Poor Interface

    If I could give this soundbar a "ZERO" I would! I purchased it after the holidays, after great reviews from CNET, and others; however, after just 3 months of use the sub-woofer and rear speaker interface will not reconnect to the main soundbar. I have tried several times to reconnect the two together with no success. I am also in the process of sending it back to VIZIO for a refund! Save yourself some time, expense, and headache and DO NOT buy this VIZIO surround set-up!27 April 2020 - Above was my initial experience with this VIZIO 5.1 soundbar. Unfortunately, I waited too long and VIZIO woul

    No Brainer

    I bought the 5.1 2018 model and the sound quality is great. It was easy to install and set up. The display on the remote makes adjusting bass, surround volume, sound settings, etc. very simple. The sound bar puts out really good sound, I switched back and forth between my tv speakers and just the sound bar itself and it's a 10x upgrade, I have a Samsung ks8500 fyi. You will be surprised by the amount of bass the sub can put out too, my neighbors sure were. The surround speakers are the cherry on top, it really makes the experience whole. I have this in my bedroom and it really is like being in

    Vizio 5.1 surround sound bar with satellite speakers and subwoofer 2017 version.

    Vizio 5.1 surround sound bar and satellite speakers and subwoofer. I love it only drawback is if you pause a movie and leave it paused for too long the sound will automatically shut off which is a good future if you forget to turn it off. One of the good features is you can hook up different components to it through HD port I have my Blu-ray player with Netflix app and other apps hooked into it sounds great to me. 2017 version

    Works great - easy to set up.

    Worked as advertised right out of the box. I connected to my old but nice LG flat-screen TV and Sony Blu-Ray player using the included optical cable. A little experimenting led me to leave most of the settings at "factory stock" values. The sound system recognized the TV's volume and mute controls - no fiddling required.The included IR remote control handles all the tweaking. My only complaint is that its miniature LCD display isn't back-lit - hard to read without bright light.I haven't tried pairing this system with my smart phone. I understand it can receive cast audio signals, and there may

    Great sound, bad everything else.

    The sound quality is really good for the price. The surround sound is great. The bass and solid. I don't have a complaint with the sound.However, I had to return one sound bar because the subwoofer stopped turning on. Was totally dead after maybe a week of use. But returned and replaced.This sound bar has a problem were it randomly turns off. It's rare, but it does it. Minor annoyance.But the biggest thing is that it loses sync with the video with certain channels. I think it's specially during commericals. I can't figure out why. But it's definitely during commericals on certain channels.I'm
