This is great for watching movies and listening to music through.

Speakers sound great and have great surround sound in both situations with true 5.1 and in those where the system needs to virtually create surround sound.

I can't add or refute praise buyers have posted for this soundbar system's audio fidelity and quality. After all, it was picked by CNET to receive the 'Best Product of CES' award at this year's Las Vegas "Consumer Electronic Show". I've waited since January to buy it, and finally, it became available locally at one of the discount box stores near me.

But, I can tell you, the unit I purchased was not ready for prime time, as several others have pointed out in their reviews. Recent reviews give me more hope. One reviewer said, "..the first unit I had would go silent when changing channels while using cable. Probably due to audio format changes between hd and regular channels but not sure. I would then have to turn the sound bar off then back on to get sound.", he said.

Folks, that was an understatement. After a pretty easy set up and using only the optical cable link from my optical output of my large flat screen Samsung to the soundbar, I immediately heard a dramatic difference in sound quality when compared with my older Vizio 2.1 system that had performed well despite it's inherent limits.

Then, using my whole system Logitech remote, I switched from a live cable program source in HDMI 1 to my Blu-Ray device. So far, so good. That is until I skipped DVD chapters or fast-forwarded the DVD. The audio dropped out and would not return unless I rotated through the various inputs to re-initialize the audio in the "optical" input on the Vizio remote. No amount of tries or even DVD changes would prevent this. Next, I tried switching to the HDMI input for the Roku streaming device, but any fast-fowarding of video of a movie in progress suffered the same audio loss, no matter if I used Amazon Prime content or Netflix.

If you'd asked me a couple years ago which 5.1 sound system to buy, my answer would have been simple: "none."

They were a big expensive pain. It seemed like my friends who had these systems would either have them only half set up (say, ditching the surround speakers) or fully set up but not used (because the input selection or the remote was too much of a pain). My previous roommate had a 5.1 "surround" system - with all five speakers under the TV. We rarely used it because we had to change 3 settings in 3 different places to make it work.

Let's review the misery of yesterday's 5.1 systems, shall we?

1) You needed to place and wire six speakers: left, center, right, left surround, right surround, plus a bass module. That's a lot of wires, speaker stands, and connections.
2) To connect the left and right surround speakers, you needed to run wires across your seating area. That's pretty ugly unless you go through the effort to make conduits or buy a special rug.
3) You needed to purchase a separate receiver to power those speakers - and connect it too.
4) You paid for all that - an absolute minimum of $400, with nicer gear easily double that.
5) You needed to manage additional remotes and settings. Good luck if you ever asked a friend to change the volume.

Well, it's almost as though Vizio started with this list, and then eliminated these problems one by one when making this 5.1 soundbar. The soundbar itself combines Left, Center and Right channels into one thin module that will fit in front of your TV, assuming you use a TV stand with at least two inches of space there. There are no speaker stands or speaker wires, and no separate receiver - the amplifier is built in!

ATTENTION PEOPLE WHO CAN'T FIGURE OUT HOW TO PREVENT THE SOUND BAR FROM GOING SILENT INBETWEEN CHANNEL CHANGING/inbetween cutscenes in a game:::
I have seen several people mention that they dislike how the sound bar automatically seems to turn off the moment it stops receiving any audio signal, even if it's very brief. I have even read how some customers ended up returning the product because they couldn't figure out how to turn off this feature. Reading the manual I found the solution where I least expected it. You can turn off this automatic default feature by turning off the VZtv Rmt setting. For some reason, they combined the automatic sound bar turn off with the VIZIO TV remote setting. Anyways, once you turn it off the soundbar no longer automatically turns off when changing channels or in-between custcenes while playing a game.

As for the rest of the product: It's great as long as you plug it in correctly. If you do not see the DOLBY DIGITAL /DTS light when you turn on your sound bar and TV, then it's because your tv is not outputting true 5.1 sound. Yes, your sound bar will automatically create a faux 5.1 surround, but for the real 5.1 quality you will have to connect your soundbar directly to whatever you are using to stream or play movies and not the TV.

Something else I haven't seen other users mention is how shows you may be watching via a streaming service, such as Netflix and Crunchyroll, will not output true 5.1 even though all the settings are set up correctly and the soundbar is lit up with the DOLBY/DTS light. It seems to be because the show you are trying to stream isn't calibrated to output at true 5.1 for whatever reason and you end up not having any output in the satellite speakers.
