The VIZIO V-Series V21-H8R is a 2.1-channel home theater soundbar system featuring two full-range drivers and a 5-inch wireless subwoofer. The 36-inch soundbar delivers a 96 dB maximum sound pressure level with a frequency response of 50 Hz to 20 kHz, providing clear dialogue and immersive audio for movies, music, and gaming.

The soundbar supports DTS Virtual:X for virtualized three-dimensional surround sound and includes Dolby Volume and DTS TruVolume sound enhancement technologies. Four sound modes — Movie, Music, Game, and Dialog — let you tailor the listening experience to your content. Bluetooth connectivity (up to 30 feet) allows wireless audio streaming from any compatible smart device.

Wired connections include HDMI ARC with CEC compatibility (HDMI cable included), optical TOSLINK, two 3.5 mm aux inputs (one dedicated for voice assistant devices such as Alexa, Google Assistant, or Siri), and a USB-A port for playing WAV files from a thumb drive. A comfort-grip remote control is included. The low-profile design allows the soundbar to sit cleanly beneath your TV, and wall-mount hardware is supported. Compatible with the VIZIO SmartCast mobile app for additional control.
