Vizio SB3821-C6 2.1-Channel Bluetooth Sound Bar with Wireless Subwoofer (Manufacturer Refurbished)

Whether you wall-mount it beneath a TV or place it inside an entertainment center, this sound bar gives your music and movies detailed, powerful audio. Its dual speakers render dialogue and treble crisply, while its wireless subwoofer gives bass and low sound effects rumbling realism.

Detailed Sound, Minimal Clutter

The 2.1-channel setup elevates your TV’s audio to give you an experience that’s closer to that of surround sound. Laterally placed speakers produce wider distribution and more realistic depth, creating a sense that the action is unfolding around you. The subwoofer intensifies the effect by adding rumbly low notes that most TVs’ built-in speakers can’t match. With only two components to install, the 2.1-channel setup strikes a much cleaner look than full-blown home theater systems.

Wireless Subwoofer: Deep Bass, Flexible Location

The subwoofer heightens the drama of movies and TV shows by sending the thud of footsteps or the roll of thunder rumbling around the room. Its wireless connectivity and single power cord mean it won’t contribute to unsightly cable nests.

Bluetooth: Stream Wireless Music, Internet Radio, and Podcasts

Bluetooth streams music wirelessly from a compatible device, meaning your smartphone, tablet, or laptop never has to be tethered to other electronics to play songs or podcasts. In turn, that wireless connection lets you double as DJ while doing whatever you please, such as mingling with guests, cleaning the house, or doing yoga.

This product was received in a timely manner. When the product was taken gently out of the box and ready for a test run, the product did not work. I’m very disappointed and want a full refund!!!

It's ok. This is my 3rd Visio soundbar/sub that I've purchased refurbished on Groupon. This one, by far was in the worst shape. Scratched sub, hole in the soundbar cover, no audio cables, and no directions. My other 2 included all of the above and were delivered like new. The sound is as good as the others but I was left disappointed with the condition of this one.
