What customers say about "Key Specs"
VIZIO SB3651-E6 SmartCast 36" 5.1 Wireless Soundbar System
  • Sound quality crisp, notice all frequencies of the surround rear speakers.
  • This is a great sound bar system and the price was much lower than comparible systems.
  • I love the sound it produces. Nice and clear.
  • It's a good sound system and sounds nice, but do your research because there's a lot of stupid short-sighted things that vizio likes to pull on you like that.
  • Sound comes out really good. But adjusting sound level is a problem.
VIZIO SB3651-F6 36" 5.1 Home Theater Sound Bar System, Black
  • Frequency response, sound quality and design are really good at this price range.
  • I paid a premium for this soundbar simply for the surround sound. The surround sound is horrific.
  • Compared to the older Vizio soundbar the sound is, well..., startling. It is very clear and very in our faces as we sit 8 feet away.
  • The sound quality was awesome, the bass was full, the packaging and instructions were well put together, and I was just really pleased overall with everything.
  • Great sound, great for movies and It'd be good for a medium to small sized room home theater setup.

What customers say about "Size & Weight"
VIZIO SB3651-E6 SmartCast 36" 5.1 Wireless Soundbar System
  • Excellent sound quality for the price. Nice footprint and super easy to install.
  • This should prove to be a versatile piece in the living room; small footprint, room filling sound.
  • It's compact, easy to connect, and will blow your socks off!
  • Compact and lightweight sound bar that you can hang or put in front of the TV and enjoy.
  • Its compact but packs a punch. It doesn't give you the object based sound but then again I don't want a lot of movies that will have that.
VIZIO SB3651-F6 36" 5.1 Home Theater Sound Bar System, Black
  • Nice and compact but huge huge huge sound from such a small footprint .... You can’t go wrong with this product.
  • I love the small speakers and the sound is surprisingly really good. Recommended!
  • It's so small, so "cute", and the sound is loads better than my previous Vizio soundbar.
  • This sound bar works great! I have a 75” tv and was worried it would look small but to me it looks fine.
  • It’s powerful and small! I picked the right one and I’m pretty happy about it. The sound is super adjustable for all basic settings.

What customers say about "Features"
VIZIO SB3651-E6 SmartCast 36" 5.1 Wireless Soundbar System
  • Excellent quality, easy install, sleek design, absolutely everything we were looking for.
  • Easy to install and great sound and volume. Has transformed my TV watching experience.
  • I use the enhanced mode not the stereo mode. It also produces good imaging although this imaging is synthetic it is realistic.
  • The only bad thing is that if the sound cuts out on the tv due to scrambled signal or something, we have to either restart the unit or slowly cycle through the input options.
  • System installed fairly easy BUT kept on tuning itself off even though ECO mode on remote was off.
VIZIO SB3651-F6 36" 5.1 Home Theater Sound Bar System, Black
  • 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.
  • Excellent sound quality and great control over tone and features ... Plenty of volume and high quality of components !!!
  • The LEDs are crap for information. You have way more control over your sound system with the phone app.
  • I own a Vizio television with Smartcast, so I tried using my Android app to connect to the soundbar out of curiosity. It detects it, but for some reason, the syncing between phone app and soundbar continually failed.
  • The soundbar LED indicator lights are very small to see and the instructions didnt indicate where they are located.

What customers say about "Connectivity"
VIZIO SB3651-E6 SmartCast 36" 5.1 Wireless Soundbar System
  • Very easy setup and connection to my system. Visio products continue to exceed expectations.
  • I'm pretty happy with this sound system. I have it connected to my LG TV and I can't stop to think that this was one of my best purchase for my living room.
  • Connects just fine to Bluetooth streaming, wifi, and to the Bluetooth woofer, very stable. I'm super impressed with this system overall, and especially for the price.
  • Connected to HDMI now and still loses connectivity. Sometimes kicks on/off randomly.
  • The problem is both the bluetooth we use to connect devices and the HDMI we use to connect the TV for surround sound get disconnected randomly.

  • 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...).
  • This was very easy to setup, a simple ARC connection from the TV, powered on the sub.
  • In the box is everything you need to connect to HDMI, optical, a/v (rca type) or coax audio. Mine integrates very well with my new Samsung Smart TV through the ARC HDMI port.
  • I was sad to find out the HDMI ARC connection on the soundbar is not 4k/UHD.
  • I bought a 4k Vizio TV and when I plugged in the HDMI, the picture size was cut down and the resolution was worse.
