No, the Sonos Ace doesn’t work as another Sonos ‘room’ in the Sonos controller. You can’t use the controller to ‘send’ playback directly to it. 

Thank you. So, at the end of the day, the Sonos Ace is just another bluetooth headphone, albeit (by all accounts) a very good one. There’s no connection between the Sonos app and the Sonos Ace per se’. Interesting….

It also can swap with the recent Sonos soundbars, to play whatever they’re playing. But they aren’t a Sonos ‘room’.

Thank you for that information. So the scenario there would be selecting the soundbar in the controller, than doing to swap with the headphones, to essentially play music to the headphones the same way we use the controller today to play music to rooms from our configured sources. I have to wonder why the swap capability is limited to recent soundbars (I do not currently have a Sonos soundbar). If I could “swap” with my Move2, that would make the headphones a more appealing purchase. My opinion of course. I thank you for your time and the information you shared.

No real data as to why that ‘restriction’, but I’d imagine it has to do with the electronics in the ‘sending’ device. The soundbars have it, other Sonos speakers don’t. But that is just a guess. 

This will not work as you have described.  You can only swap the ACE with the soundbar when it is receiving an HDMI input from the tv.  You would not be able to select a music source in the SONOS phone app, play it on the ARC, and swap to the ACE.  For music to swap from the ARC to the ACE, you would have to have a music service installed on your tv or streaming device as a music source.  Someone correct me if I am wrong.

Thank you for that information, Very useful. It strikes me as odd that Sonos, whose products I have a lot of and have been using for many years, would introduce a headphone that has zero integration capability into the Sonos ecosystem. Granted, by all accounts it’s an excellent bluetooth headphone, but there’s no shortage of quality bluetooth headphones out there. The real value proposition for me would be a quality headphone that is integrated into the Sonos controller. I do understand there are very serious physical constraints in terms of the space available to engineer electronics into a headphone, and perhaps therein lies the reason ACE is just another bluetooth headphone, albeit a damn good one. Just my opinion of course. Thanks all for sharing this information. 

I wouldn’t say zero integration or just another bluetooth headphone, but I understand where you are coming from.  I find the ACE swap feature invaluable for my use, and it is a direct wifi, not bluetooth, connection to my surround sound system.  It just works every time without having to fiddle with bluetooth settings on the tv, and I find the surround sound features to be very good.  

I feel silly and the spouse mentions our power bill when I fire up the big TV, bring my Arc Ultra, Sub and surrounds out of sleep just to stream Amazon Music from my FireStick or play something from my music library.

I'm sure loading apps and streaming Bluetooth would be a better solution, but doing it even just on the five devices I usually throughout the day would be an aggravation.

I too, am flummoxed that there is no integration into the sonos ecosystem. Id buy that headset in a heartbeat. This one? No thanks.
