Hear Immersive Sound Come 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.

Surround Made Simple

Using front speakers only, Sony’s unique digital sound field processing technology virtually reproduces the surround sound field, with audio coming at you from both sides. 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

Front speakers feature an X-Balanced Speaker Unit. 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.

Deeper, Richer Bass Sound

A powerful wireless subwoofer with a large 160mm speaker unit delivers a deeper, richer bass sound.

Simple And Easy Operation

The simple, compact remote control and convenient OLED display window make operation a breeze.

Comfortable Control

A simple new remote control combines 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 soundbar 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.

Easy Wireless Connection

To minimize cable clutter, you can send audio wirelessly to your soundbar from a Sony BRAVIA TV supporting wireless connection. 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.

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.

Effortless Control With BRAVIA TVs

With an integrated UI, soundbar settings automatically appear on the BRAVIA TVs Quick Settings menu for easy control of sound settings and volume.

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 input, 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.
