There was a problem filtering reviews right now. Please try again later.
A lot of reviews talk about the issue with pairing/loss of connectivity of the wireless sub woofer and the bar. I have a theory about this. I have 2 of these soundbars - a 45" and a 40". The 40" has a more recent date (sticker located on sub woofer). My 45" was from early-mid last year. My 40" has had absolutely no problems whatsoever - it was paired out of the box and had no subsequent issues. My 45" was not paired. After many attempts I got it to pair. That worked for about a week before never pairing again. I started getting odd behavior where I could not get the subwoofer to go into pairing mode. On occasion it would go into the pairing mode, connect, and then immediately disconnect. Luckily, Vizio has excellent customer support. I chatted with a service rep at 10pm who quickly arranged for a replacement unit to be sent. I appreciated the trust that it was a defective unit and not user error. 2 days later I received a new unit manufactured in Dec. 2016 and I have had absolutely no pairing issues. My theory is that the subwoofers manufactured early to mid 2016 have defective hardware that has since been corrected.
I am not changing the score of my review for the following reasons:
1. Excellent customer service
2. Quick hardware replacement
3. Excellent product when working properly
I hate the following things: visible wires, big boxy dumb looking bass speakers, big bulky sounds bars, audio receivers, and hiring contractors. With this system you can avoid all of these things and still get awesome cinematic surround sound. Vizio truly innovated and evolved here and it totally paid off.
Here is what you get:
- Unbelievable high quality 5.1 surround sound
- Wireless connectivity between sound bar and bass (bass connect to surround speakers by wire)
- A great Bluetooth setup for audio
- Google Cast capable speakers that can be used with other google cast speaks (Sonos style)
Pros:
- Incredible sound, clean and crisp, no hissing at all
- Very small attractive sound bar.
- Loud. This thing rocks and sound is clear even at the highest levels. Guaranteed to fill any large room.
- Slim bass unit that can easily slide under your couch (gives you an Imax couch shaking bass experience which is just awesome).
- It's all about the bass - this bass is booming and will rattle your entire house and maybe your neighbor's too. I actually turned mine down a notch in the settings because they are that powerful.
- Excellent connectivity - I am yet to have a single problem with the speakers synching with the sound bar.
- Great using HDMI-ARC, no lag/synchronization issues and it plays nicely with my Samsung
- Excellent remote with informational display
- Amazing value - cheap and no receiver or contractor required
Cons:
- Probably not the best speaker to use for music if you are an audiophile (which I am not)
- Some complain about the dot display being confusing - does not bother me at all thanks to the amazing remote
- Possibly not Vizio's fault, but I always seem to have issues with Google Cast
- The Vizio Cast app sucks
Tips:
- Definitely slide bass under couch if possible
- Get small speaker stands as the satellite speakers are tiny and will look ridiculous on a heavy stand
- I cranked the Surround setting all the way up as I found it to offer a much more immersive
- Buy it
However, there are some serious annoyances:
1) With audio coming in through the HDMI IN port and then the HDMI out going to my projector (not using HDMI-ARC), about every half an hour the audio will cut out for 5-10 seconds. This has happened with my Roku, my Fire TV, and my Steam Link. It's very annoying in the middle of movies.
2) The unit has "crashed" a few times already. That means the power stays on and the controls still work, but the HDMI sound stops working and no video is sent through to the projector. Turning it off and on doesn't do anything. I have to physically unplug the power cable and plug it back in, and that fixes it. I've had to do this twice in the month I've had it.
3) The unit forgets its settings from time to time. I can't tell what is going on with this, but every so often (happened twice so far) it would just lose some of its settings, such as its eco-power mode that automatically turns it off after a while or even its Google Cast settings and, on one occasion, its subwoofer pairing.
Edit: 4) After a few months, the subwoofer and rear speakers stopped pairing altogether. No more bass and no more 5.1 sound. I powercycled and hard reset and re-paired more than a dozen times over the span of a few days, hoping to do something different... out of those times, it finally reconnected only one time and then disconnected a few hours later. I gave up altogether after that. Will be sending this in for a refund or replacement.
Definitely do NOT recommend this. Original review was 3 stars. Changed it to 1. I never had so much trouble with an electronic device -- and I loved other Vizio products. My much simpler 2014 Vizio 2.1 soundbar had no issues of the sort. This is just a lemon.
Stay far, far away from it.
