I have a Bose Soundtouch 300 with rear surrounds and Bose Acostimass 300 subwoofer. Until now, I have been pretty well satisfied with it. My TV is an LG 65C7P OLED and I watch as much 4K as I can, mostly using Netflix.
Last night, I purchased the Microsoft Dolby Atmos Access app for my Surface Pro 4 Windows 10 computer. I was leary to spend $15 for this app, but decided WTH, why not? I have to say, I am totally blown away watching Dolby Atmos Netflix on my computer and using a cheap pair of wired Ear Protection headphones to hear the ATMOS sound. It is totally awesome and I am really surprised that this techology actually works with a cheap pair of headphones.
I am now convinced I want a state-of-the-art Dolby Atmos 7.1.4 system, no more 5.1 or soundbars for me. I don't know when I will update, but when I do, it will be Dolby Atmos. I'm almost ready to head over to Best Buy and pick up an Atmos receiver and two Bose Acoustimass 10's and try it out as a Dolby Atmos 5.2.4 or 7.2.2.
My advice is don't buy any system that is not Dolby Atmos capable. You're just missing too much without it. Of course, you need a Dolby Atmos source.
Update: I'm currently trying to figure out if and how I can listen to Dolby Atmos directly from my LG TV using a pair of Bluetooth headphones. While the TV is supposedly Dolby Atmos capable, it can only pass that signal via the single HDMI ARC. Optical is not capable of passing the Dolby Atmos signal. I guess I could use optical to my Bose Soundtouch 300 and purchase an HDMI to Bluetooth adapter to plug into the HDMI ARC. That might be worth a try. Just need to order a cheap pair of Bluetooth headphones and an HDMI to Bluetooth adapter from Amazon. I'm not sure if an adapter such as that will pass Dolby Atmos or not.
Update 2: Well, I'm now thoroughly confused. I'm not sure there is any way to get Dolby Atmos out of my LG TV to a pair of Bluetooth headphones. If anyone knows this stuff better than me would chime in, I would appreciate it. For now, I can receive the Netflix program on my computer and listen to Atmos via my cheap headphones. I have the option to cast the video to my LG TV using a Microsoft wireless display adapter that works very well. It's just cumbersome.
Update 3: OK, if anyone has read this far, would an Apple TV 4K send Dolby Atmos out via bluetooth to bluetooth headphones? That seems like an expensive way to do it, but that would allow me to watch Netflix 4K, Dolby Atmos on my LG 4K TV and use my Bose Soundtouch 300 for 5.1 sound or wireless headphones for Dolby Atmos sound, I think. I guess the place to start is to buy a bluetooth headset and see what I get connecting directly to the LG TV. Then, purchase an Apple TV 4K if I'm not getting Dolby Atmos to the headphones.
