Simple and easy operation with compact remote and convenient OLED display window

A simple new remote control combines a comfortable hand-fit design with easy and intuitive operation. An OLED display window on the soundbar offers at-a-glance status information such as input source, volume, and sound settings such as Sound Field, Voice mode, and Night mode.

Flexible layout with wireless connection to compatible BRAVIA TVs1

Minimize cable clutter by sending audio wirelessly to your soundbar from a Sony BRAVIA TV that supports a wireless connection. The wireless connection also lets you turn your TV and soundbar on and off simultaneously using the BRAVIA power button – all without using up a Bluetooth channel, allowing for another input source such as a smartphone or tablet.

Wall-mountable design with a flush fit

Designed to blend seamlessly into your living room, the wall-mountable HT-S400 soundbar has a flat back that fits perfectly flush with the wall.

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.

Bluetooth® connectivity for wireless audio streaming

Easily play your favorite music through your soundbar too. Use Bluetooth® to wirelessly stream music from your smartphone, tablet, or laptop.

Connect to your TV with either HDMI ARC5 or optical

HDMI ARC lets you connect to compatible TVs with a single cable, reducing cable clutter. Enjoy high-quality sound in movies and more when you connect to the optical input.

Sustainability in mind

Sony's products are designed to pursue sound quality and consider the environment. Sony’s originally developed recycled plastic is used in the rear panel of the HT-S400’s subwoofer, reflecting how Sony strives to reduce the environmental impact of Sony's products and practices.

Seems to have an issue with randomly turning itself off that can't be fixed with automatic standby function or reset. Will need to return if the problem continues.

Awesome Sound bar
For just 2 speakers and a subwoofer you get and impressive sound effects that give you virtual surround sound. And the subwoofer adds a quality I didn't know was missing, the tonal quality of voices, explosions and sound effects.

Great Starter Soundbar
I bought this to blast TV and music while on my loud treadmill. It's not a 4k pass thru it just a basic model that works great for my old TV. The price reflects this as well! Easy set up, love it!

Terrible sound bar
I bought the HSD40 sound bar Christmas for new Samsung tv. It works for 10 to 60 minutes then go's searching for Bluetooth and the sound stops. Then you have to hit input on the remote to tv and it might last 15-30 minutes before you have to do it again.
Very disappointed in Sony

Great for the price
Good link to TV via HDMI cable (not suplied). Volume could be a little louder but sound quality is good for the price. Bass is pretty good from subwoofer for music.

Can I add wireless speakers to this setup in the future?

  Thanks for your inquiry. Sony SA-RS5 and SA-RS3S are only compatible with the Sony HT-A7000/HT-A5000. They offer no optional wireless surround speakers for the HT-S400.
