360 Spatial Sound experience, like you're in the scene

Surrounded on all sides by multiple phantom speakers within an optimized sound field, you’ll hear every flap of wing and gust of wind with incredible intensity. It’s like you and your living room are inside the movie.

Poor wireless speaker connection
I purchased this 3 weeks ago. Setup was easy and I liked the room EQ feature. However I continually hear audio drop outs. Not what I expected for $1800. The sound quality was ok, but expected much better at this price point. You definitely need to purchase the subwoofer for better bass response. I've heard ATMOS systems before with Upfiring speakers and found the effect hard to hear on the Sony system. Not sure what 360 is or does so I can't comment. In the end I wish I would have purchased a different wireless solution. I've heard the Klipsch wireless systems which worked flawlessly and sounded great! I was told by the Best Buy sales person it used the WiSA standard.

Perfect sound system for condo living (As-Is)
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, and Sony gives you a code for a free 30 day trial - DON'T PICK AMAZON MUSIC!!. There are literally only 39 songs available, and while they sound really good, they are all perfect for the spa or a massage. C'mon! If you decide to check it out, and I think you should! Research each option to see who has the biggest catalog. I basically threw my free coupon away by picking Amazon, so I have to decide whether or not I want to pay for a month on the other services. I will find out who has the most content first!

Back to the system. Pairing this with my BRAVIA XR A80J makes the integration seamless. Only one remote is needed (makes the spouse happy), and it is aesthetically pleasing in the room.
