Best Sound Bar Under $500

I tried several soundbars with a Subwoofer and they all disappointed until this one. It's sounds way better than it should for it's price point. Plays way bigger than you'd expect - I'm 100% satisfied to say the least. Great bass and voices are crystal clear. I highly recommend it as a perfect match for any TV.

Junk!!!!!

Absolute junk. First two weeks was awesome. Then the subwoofer kept cutting in and out. Updated firmware like Vizio said and now it doesn’t recognize subwoofer. And Vizio customer service? Impossible to get a hold off. So I’m stuck with junk. Don’t buy Visio

Downgrade compared to my old, cheap Vizio V-Series

My previous ~$180 5.1 Vizio sound bar crapped out after 3 years. I bought this M-Series @$250, vs the lower ~$180 V model on the shelfs as of May 2023. So for what it's worth, this should be an UPGRADE to my prior system. This sound bar is WORSE than my old Vizio sound bar. My wife used to get mad about how much base and subwoofer I would add to the old vizio sound bar, however, she and I both agree, even with this M-series soundbar cranked up with max bass, max subwoofer, lowering center and treble, we can't get enough bass at all... It really feels like a super small upgrade to tv speakers.

Superb sound bar system

This is a great sound system. Very clear midrange, sparkling treble and booming bass. Better than expected.

Awesome Sound Bar

The VIZIO M-Series 5.1.2 Immersive Sound Bar with Dolby Atmos and DTS:X is an awesome sound bar and well worth the price that I paid. The quality and sound are awesome.

Good but not for long

It provides great sound and bass but after a couple of months it started to lose connection to the rear speakers. Wish it could work as it did on the first day.

It won’t last

I bought system just over a year ago. Everything worked great and sounded good. Just after year now it won’t stay connected to any devise. The sound will drop off after10 minutes. It doesn’t matter if I use optical, HDMI, OR HDMIARC, or Bluetooth.
