Great Sound, Easy setup
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.

Excited still very new to us
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.

Sounds great, but input latency was surprising
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.)

Excellent sound for the money but wall anchoring i
The sound from this system is excellent for the money. My only complaint is that the wall mounting holes of the rear of the sound bar are 36" apart. Since typical wall studs are 16" apart on center, the sound bar must be mounted using sheetrock anchors. This is certainly not as secure as anchoring directly into wall studs.

Sound quality is outstanding
I got this as an early Christmas gift from my brother and we are enjoying AGT more than ever before. The surround sound is just like I had 4 speakers around me. The subwoofer has the best bass I've experienced since unplugging my huge floor speakers. Happiness all around!

Not worth the cost.
Had this now for just about a month, and I'm not even remotely impressed with it. After getting everything plugged in, connected, and set up, the sound from this speaker set lags behind the items being watched. Attempted to adjust settings, but it still lags. My last sound bar cost less than half this one, and the quality was much better. Would not recommend this to my friends.

Can I add wireless speakers to this setup in the future?
Doug D on Oct 8, 2022
  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.
