Enhance your TV’s sound and enjoy Bluetooth audio streaming with the Sony HT-S400 330W 2.1-Channel Soundbar System. It connects to your TV with just one HDMI or optical cable, or wirelessly to compatible Sony BRAVIA TVs. Voice Mode makes it easy to hear dialogue over sound effects in movies and TV shows. You can mount the soundbar flush to the wall with optional hardware to create a sleek look.

Hear Immersive Sound from All Around
The HT-S400 soundbar couples high-quality Dolby Digital with S-Force PRO Front Surround to put you right at the heart of the content you love. Using only the soundbar’s speakers, Sony’s digital sound field processing technology virtually reproduces the surround sound field, with audio coming at you from both sides so you can enjoy rich, cinematic surround sound.
Enjoy Clear Dialogue and Powerful Sound
Powerful audio technology, such as the X-Balanced Speaker Unit and Separated Notch Edge, works to deliver wide-ranging sound and enhanced vocal clarity.
X-Balanced Speaker Unit
The soundbar’s speakers feature X-Balanced Speaker Units. The unique rectangular shape of these speakers maximizes the diaphragm. It reduces driver excursion while maintaining sound pressure, resulting in less distortion and greater vocal clarity.
Separated Notch Edge
The Separated Notch Edge on the X-Balanced Speaker Unit improves vertical amplitude symmetry, an essential for clear sound quality. It achieves this using strategically placed cuts on the edge, which help to control the stress inside and outside the edge of the diaphragm.
Deep, Rich Bass
A powerful wireless subwoofer with a large 6.3″ driver unit delivers a deeper, richer bass sound.
Simple, Comfortable Control
The simple, compact remote control and convenient OLED display window on the soundbar make operation a breeze. The remote control combines a pleasing, hand-fit design with easy, intuitive operation. Convenient features include dedicated buttons for adjusting the volume and sound settings.
Simply Select Your Sound
The system offers a choice of sound settings to suit whatever you’re watching or listening to. There’s Voice Mode for clearer dialogue, Night Mode for when you want to watch TV without waking the house, and Sound Field, which converts conventional soundtracks such as stereo audio into a surround sound experience.
Convenient OLED Display Window
An OLED display window on the soundbar offers at-a-glance status information on remote control functions including input source, volume, and sound settings such as Sound Field, Voice Mode, and Night Mode.
Wall-Mountable Design with a Flush Fit
Designed to blend seamlessly into your living room, the wall-mountable soundbar has a flat back that fits perfectly flush to the wall.
Play the Music You Love
Easily play your favorite music through your soundbar, too. Use Bluetooth technology to wirelessly stream music from your smartphone, tablet, or laptop.
Set Up in Seconds
With a choice of HDMI ARC and optical inputs, it’s easy to connect the soundbar to a range of TVs, so you can get on with enjoying your movies, music, and more.
HDMI ARC (Audio Return Channel) lets you connect to compatible TVs with a single cable, reducing cable clutter.
Optical Input
If your TV is not compatible with HDMI ARC, you can still enjoy high-quality sound for movies and more when you connect to the optical input.
Sustainable Design
Sony’s originally developed recycled plastic is used in the subwoofer rear panel of the HT-S400, reflecting how Sony strives to reduce the environmental impact of their products.
Easy Wireless Connection to Compatible BRAVIA TVs
To minimize cable clutter, you can send audio wirelessly to your soundbar from a compatible Sony BRAVIA TV. The wireless connection also lets you turn your TV and soundbar on and off simultaneously using the BRAVIA power button. And it frees up a Bluetooth input for another input source, such as a smartphone or tablet.
Effortless Control with Compatible BRAVIA TVs
With an integrated UI, soundbar settings automatically appear on the BRAVIA TV’s Quick Settings menu for easy control of sound settings and volume.
