Hear sound come from all around

The soundbar couples high-quality Dolby® Digital with S-Force PRO Front Surround, our virtual surround sound technology. It puts you right at the heart of the movies you love by emulating cinema style surround sound.

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 speakers work together to deliver wide-ranging sound throughout your room, with technologies such as the X-Balanced Speaker Unit and Separated Notch Edge on the speaker unit helping to enhance vocal clarity. So whether you’re watching movies or TV, you won’t miss a word of dialogue.

X-Balanced Speaker Unit

Front speakers feature an X-Balanced Speaker Unit. The unique rectangular shape of these speakers maximises the diaphragm. It reduces driver excursion while maintaining sound pressure, resulting in less distortion and greater vocal clarity.

Deeper, richer bass sound

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

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.

Easy wireless connection[FN|Wireless TV connection not supported on HT-SD40.]

To minimise cable clutter, you can send audio wirelessly to your soundbar from a Sony BRAVIA TV supporting wireless connection.[FN|Wireless TV connection not supported on HT-SD40.] [FN|As for Wireless connection via Bluetooth®, BRAVIA™ TVs supporting Bluetooth® A2DP ( Advanced Audio Distribution Profile) is needed. Applicable TV models https://www.sony.net/bluetooth-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.

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.

Stylish, wall-mountable design

Designed to blend seamlessly into your living room, the wall-mountable soundbar has a flat back that fits perfectly flush to the wall.

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.[FN|Integrated UI works with the following models: Z9J series, A90J series, A80J series, X95J series, X90J series, X85J series, X80J series, Z9K series, A95K series, A90K series, A80K series, A75K series, X95K series, X90K series, X90S series, X85K series, X80K series.

HDMI ARC (Audio Return Channel) lets you connect to compatible TVs with a single cable, reducing cable clutter.

Play the music you love

It’s not all about movies and TV – you can easily play your favourite 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.

Optical input

TV not compatible with HDMI ARC? Enjoy high quality sound for movies and more when you connect to the optical input.
