I bought this just over a year ago. The sound is superb and it is easy to setup. However it has intermittently had audio drop outs. It was for a while possible to fix this by toggling the RF option in settings. However over the past 2 months it has got much worse. Sometimes the audio just stops outputting completely and I have to reboot the TV and set up the speakers all over again - but that does not always solve it. So, frequently I am spending 15 to 20 mins to get this to work again. It is so annoying that something so expensive has such a poor warranty. The retailer has said they cannot help. Expensive junk.

It would have been a great product had it not been for the audio drop outs that occur even with audio optimisation. This is because the WiFi technology that this product uses is prone to WiFi interference.

Only tried the 4 speakers for a short period, they are well made and do generate a surround effect, however as a replacement for my old 7.1 surround system they are lacking base impact, both with music and especially sound effects. So I'm saving for one of the 2 available subs that are compatible. Another thing to consider on positioning, you may have to buy longer mains cables to get them ideally set-up.

This is an impressive for sound but the constant dropouts in sound when playing Atmos or other hi-res formats leaves you feeling why did I buy this. Changed constant settings as per manual but still dropouts, normally in the quieter passages too? ??

I've had the soundbar for over a month now, connected to a Bravia 7 TV. Overall, it's an exceptional product. The spatial imaging is pretty good for the form factor of the soundbar, it does a good job of 'thowing its voice' to make the sound stretch beyond bar's physical limits. I have it connected to the TV to make the center channel the TV's speakers, so dialog is fantastic and not hard to understand as is way, way too common with recent movies. The only gripe is having to use the Bravia app on my phone to set up the soundbar, it would be nicer if I could do it on my TV. Except for that, it was worth the money.

I bought the Sony A9 sound system a few months ago. Fortunately for me, they came with a 14-day return policy. Although I liked them a lot, I returned them when I discovered the new Sony A9M2 had just been released. In my opinion, newer has to be better....and they are. Better looking and the sound is also better. I'm now waiting for to pair them up with the new Bravia 9 TV.

Grande Prodotto . Facile da usare ed installare. Peccato per il canale centrale. Il centro sync funziona solo con i nuovi TV Sony e non con quelli che hanno qualche anno. Spero che gli ingegneri della Sony se vogliono possano risolvere il problema Buona Musica a tutti Valentino

The sound quality is really good, but if you are living near block of flats with many wifi networks , you will suffer from sound dropouts. Sony should at least add the option to select the preferred wifi channel manually and also option to save the last used channel. As of now the system forgets the last used channel and you will again need to scan for good wireless channel every time you turn on the system.

We have had this sound system for a couple of weeks now and are still amazed at the clarity and depth of the sound. It was easy to install, and, as we love our music, we bought the woofer as well and this fills our living room with an incredible sound?..almost as though we were in a concert hall. I love it and am so glad we decided to buy this system.

Not bad for one little box. I think it's helped by using the Sony TV as the centre speaker. Disappointing there is only one HDMI and occasionally it's slow to respond

The plus side first: it creates a brilliant immersive sound and delivers unbelieveable nuances in my music (particularly those which have been produced for immersive sound, of course). Balancing the speakers was easy using the setup process, given the limitations of having to set up the speakers within specific distances from electrical outlets in the room. The fun bit. Obviously there was some connection between the control box and my TV as the menus appeared on screen but.... the HDMI supplied was not reading at all to connect TV mode to the box so no sound and an error message told me that there was no HDMI plugged in!!! I checked everything, including resetting my Sony TV to ensure that it was set to use the right HDMI outlet for sound and that the TV was to work with an audio system. Still nothing. I happened to have a spare HDMI cable which I plugged in instead and huzzah!!!! It turns out that the HDMI supplied wasn't fully functional. At least I had a spare to check it all out.

Overall a break through for wireless home theater sound system. However, probably need to update the firmware as the system request to remap the system quite often.

I brought this month ago, glad that its performance is as expected. Definitely need a subwoofer with this to add the punch. Does good job with reproducing good audio for the streaming movies. Streaming music is not as expected and is dependent on service which are not alike, needs improvements. Setup is simple and its placed in 12x12 room, not sure how it will perform in large space or high ceilings. Wish it had come with built in demo music and video clips with original content.

Recently bought to go with Sony X95L 85 TV. extremely easy to set up. Wireless connection resulted in frequent dropouts, though it is inches from Wi-Fi. I connected with ethernet, so far very stable Works best with ethernet. I am using TV speakers as centre speakers. Is it possible to add another subwoofer Firmware update?? overall great buy especially at great black Friday deal.

It might be expensive, but you can't argue with the sound quality from the HT-A9. The 360 spacial sound mapping will blow your mind. The speakers are so simple to set up, just plug them in and follow the instructions on the screen, it does everything else for you. It definitely sounds like you have a lot more than 4 speakers, it's a smart bit of kit. Although 'wireless' you obviously still need to plug the speakers into a plug socket, which can be tricky depending on where yours are located. I found the length of the power cord far too short for 3 of the 4 speakers, so ordered IEC C7 Figure 8 Extension Power Cables and this did the trick. For the cost of these speakers, I would expect them to come with the subwoofer and not sold separately. That, and the very short power cables, are the only reasons I've not given 5 stars.

Bought this a month ago. So far so good. Satisfy with the sound and surround. Just wonder why sound become softer during netflix 4k movie. Usually volume tune at 40 will be loud enough but during 4k netflix movie, volume need to increase till 70. Is there any fix or setting i can solve this?

I've had this sony system for about a month and it replaces a Samsung system.the difference is very noticeable, the Sony is a great improvement over the Samsung.

An excellent set of speakers, i was worried at first by the lack of a centre speaker, but the sound mapping is so good that you do not notice that it is not there. The proviso - you really do need to add the optional bass speaker to get the best out of this set up.

I recently purchased a SONY HT-A9 Home Theatre Sound System & it's amazing there are 2 issues that I was quite concerned about, the S Centre Speaker & the Pass Through which they recently did an update to rectify that Pass Through issue. The S Centre Speaker is a different issue altogether when connected to my Tv there was a loud continuous hissing sound & SONY had to arrange for an engineer to come out & change the TV's Motherboard which rectified that hissing issue. You then had to redo the whole setting up of the TV again which I suppose was a minor in the whole scheme of things. My annoyance also comes from the cost of this premium product, I was lucky the price had been reduced but it still cost a considerable amount of money !. SONY need to do better, but the sound from that system is amazing & sublime it does what it says on the tin, & that's why SONY are the very best at what they do.

Perfect sound system for condo living (As-Is)
By Bobert63
I bought this last month and finally relied the product today. I paired it with my Sony BRAVIA XR A80J, and connected the Center channel Sync cable. Movies sound incredible, and the surround is amazing! I don't have the sub-woofer, because I am in a condo and don't want my neighbors banging on the ceiling or floor during action scenes, but if I was in a house I would definitely add the sub, for the full-on theatre experience. One thing I want to add is the 360 Reality Audio sounds amazing, a...

Better Than Expected
By Pirate 2.
I have had the HT-A9 for about two weeks now. Setup was real easy. The sound is better than expected. Not using the TV as center channel and the dialog is still spot on. Surround effects are realistic. I am real happy with the setup. They are wife approved also because they look nice and clean. I do have a full Home Theater in a different room with a 120" screen that sounds better, but for my family room within a 65" Bravia where I used to have a soundbar this is night and day better.
