Review Summary
2025-07-03T20:00:00
Lousy warranty. Died 6 Months out of warranty sound bar died. All Sony would do is pay for 1/2 of the repair. I had to provide box., pay shpping and wait for repair estimate. It was hard to find a customer service phone number and they don't advertise their hours.

I purchased this sound bar 3 months ago along with my sony 50" smart tv. While the bass is good for watching action films it is very disappointing for dramas trying to make out what people are saying. I have just finished watching Adolescence on Netflix and it was nearly impossible to make out episode 4. Very disappointed with purchase.

Did a lot of research on both Sony and Samsung TVs and Sound Bars. Since I have been a Sony guy for over 45 years, I obviously was leaning towards Sony. But after looking at all products and display and hearing the sound bar comparisons, I was convinced that the Sony was far superior. After the EASY set up we enjoyed the immersive viewing and sound. Great Products! Thanks Sony! And Thank You Best Buy!

Simplicity itself to set up and operate but why you do not include an HDMI cable with the product is baffling - it seems like penny pinching when dealing with such a quality product. Otherwise the purchase has been well-made and produces first class sound in my room.

After being installed the blue tooth music skipped. You have to turn off the sound bars and then unplug it, wait for 1 minute and then plug it back in. That solved the problem.

I was excited because it sounded so good on the display model. Got it home and not so much. No adjustments besides preset and bass volume. And everything we watch has a different sound level. Some have to be all the way up to hear it. Others on 15 setting. Would not recommend

This sony soundbar has a good sound quality overall but is a bit too bassy, and can get noisy easily, especially in a small room. The setup was very easy. The subwoofer is the best part of this set, if placed correctly it has amazing quality. I would recommend it more for tv than for music.

I recently purchased a lower priced Sony Model to complement my Sony Bravia TV. Together, I have a great TV and better audio. If you don't want to spend the extra on a high end sound bar. I recommend this unit.

I bought this as a replacement for a less expensive sound bar from another manufacturer and there is simply no comparison.

I Love the sound depth and ease of connectivity with Smart Tv even from different brands. The Sound bass is abit low for a music listener. Aside from that the aesthetic value is good for home decor.

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.

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.

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!

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

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.

We just purchased the sound bar to compliment the Bravia 65" TV that we just purchased as well. I was surprised by the ease of set-up. I have a smaller living room and the sound is really good with good bass and clarity. Only thing is that I wish that the eARC HDMI cable was supplied. I have ordered the cable. Can't speak to longevity or customer service, but if they are like all the Sony products that I've owned in the past, I think that I'll be happy.

We received as a gift from our Son on December 1st as an early Christmas present so we are excited to enjoy it for many years we hope. We previously owned a different brand that we had about 15 years without any extended warranty and never a problem until it died. So we hope Sony is as good a product and will last for years without extended warranty as well.

This HT-S400 is being used to replace a very old and inexpensive sound bar / wireless woofer, being used on an equally old plasma TV. The bar sounds quite good - I have no issue with the audio quality and the remote woofer is marvelous with good solid bass. I am using the toslink optical connection just as I did with the old soundbar - and was very very surprised to hear a significant lag in the audio between the bar and TV! It introduces a quiet intrusive echo effect - the only way which can be resolved is to turn the TV volume to zero. While some TV's may have options to increase the audio latency to match an external soundbar mine does not. This issue did not exist on my ancient cheap soundbar that it was replacing. The old soundbar has no discernible lag. The issue is easy enough to avoid - just mute the TV. But still, it was unexpected - could the latency issues be something Sony could improve with a firmware update? Updating from Canadian firmware 1.114 to 1.188 made no difference. (I mention "Canadian version" because it seems other countries have a higher firmware version number 1.195 but release date is the same - SONY, this seems very odd.)

Rich surround sound for all your content
A wireless subwoofer with HDMI ARC one-cable connection make watching movies and TV more immersive. Deeper, more engaging bass performance in music, movies and gaming make it perfect for the essential home theater.
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.1,2 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
HDMI ARC (Audio Return Channel) lets you connect to compatible TVs with a single cable, reducing cable clutter.
Optical input
TV not compatible with HDMI ARC? Enjoy high quality sound for movies and more when you connect to the optical input.
