I purchased 2x of these units one for my 65X900C in the living room, upgraded from DDW7500. A second one for a 55X8500G that I used in my bedroom, I have replaced the bedroom TV with 65XR70, just recently and I am very happy with the sound quality. The rear wifi speakers can sometimes cut out as does the sub due to sharing the same 5Ghz Wifi band. I have found the speakers still make streaming 4k via TV apps fine and both picture and sound as expected with UBP-X700

I have had this unit for 12 months. Could not be happier with this unit. Crisp sound and easy set up.

I bought this Sony 5.1 Dolby Atmos Sound bar very recently to compliment my Sony 65 A1 4K Oled TV and PS4 Pro and honestly am very, very impressed with how it has come together. It easy to set up and operate with a clear crisp treble and good deep bass which can be independently changed within each speaker and sound bar alike and the added feature of the virtual sound is also a very cool feature. The Sound quality and choices that are available, not only for the PS4, but Cinema, News, Music and Sport's choices are both very different from each other but brilliantly compliment with what your specifically watching on TV. And to operate this directly through the remote and sound bar and not have to do this via the TV is also both clever and much preferred operating choice. I'm truly impressed with the immersive sound quality of each of the surround speakers and sub-woofer when choosing the "Game Studio" sound option for playing the PS4 Pro and this option alone would have sold me on this sound bar but all of the different sound options do have true effect when listening to different types of sound options to compliment the visual choices you make on the TV. Nice work Sony!
