Vizio 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.

Bluetooth: Stream Wireless Music, Internet Radio, and Podcasts

Bluetooth lets you stream wireless music from an enabled mobile device, leaving you free to mingle with guests, clean the house, or do yoga—all without interrupting the music. Moreover, Bluetooth plays your favorite songs over the system’s speakers, filling the room with richer sound than most smartphones, tablets, or laptops can.

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.

About Vizio

Launching in 2002, when rival companies had been selling TVs for decades, Vizio may be a relative newcomer to the TV market, but it hit the ground running. By 2007, it sold the most LCD TVs in America. Its runaway success is thanks in large part to its bread-and-butter HDTV, the LED-backlit 1080p set that can be found in most living rooms. Yet the company also takes chances on the latest technologies. In 2015, for instance, it launched what is arguably one of the most high-end sets ever produced—the $130,000 Reference Series, a 120” 4K set with support for more than one billion colors and integrated 5.1-channel surround sound. While the hefty price tag will deter most TV shoppers, Vizio will inevitably find a way to pack the cutting-edge technologies into a more consumer-friendly set—the approach to TV-making that brought it success in the first place.

Outstanding product. Works very well and the sound is way better than I expected. Liked it so much that I bought another one for my bedroom.

I’ve had this unit for almost exactly two years now. It worked perfectly the first year, but the second year the subwoofer died. We will see how long the soundbar lasts...

The item was great for the the first couple months, but stopped working after the 30 day warranty expired.

Poor sound quality. Poor remote control connectivity.\nStopped working 3 months after purchase. Expected a 1 year warranty but now I see it was a 30 day warranty called a VIZIO Recertified C Grade Warranty - so I expect that means the product is junk to begin with.\nTime for me to stop trusting anything Groupon sells.

I would say I was initially impressed as I was able to use the ports to hook up several different pieces of equipment. However, after only using it a few times, the soundbar shutdown while I was watching a movie and I have not got it back on since. Tried a different power cable to make sure it was not that but it still would not come on. So it seems the power supply was fried within 60 days of having this and only using a handful of times. Depending on how the return policy goes, I may come back to re-rate this higher than 1 star.
