HI ​@SarahN 

Yes - as I understand it, that would be no issue at all. Only groups are affected by Linking, and Line-In is a viable source for Ace Ultra.

Fantastic - thanks ​@Corry P 

Super excited now to receive my Sand coloured Ace Ultra headphones. My previous Ace headphones are now owned by a chap who bought them off me via eBay and he’s extremely happy with them which is great!

If the audio is pulled from an active group of speakers using the Content Key or the Sonos app, that group will be disbanded. Other types of bonded/paired rooms/zones will remain as they were. Disbanded groups will not be re-grouped when the content is pushed back to a speaker using the Content Key on the headphones - indeed, the content might not even go back to a speaker that was in the group initially. The Sonos app can be used instead of the Content Key when pushing content back to a speaker, in which case the user has control over the destination, and can regroup the speakers from there.

 

 

Based on this statement above, it seems that the Ace Ultra cannot be a part of a group in any scenario.  You stated that establishing the link to a room will disband the group the room belonged to, so Ace Ultra is obviously not a part of a group that way.  You also stated that rooms can regroup after content is pushed back from the Ace Ultra to a room.  You didn’t say that Ace Ultra can be grouped with other speakers while it’s linked.

I can see why that’s not really an important use case for a lot of people, but like is the case for TV swap feature, people will want to listen to headphones while others are listening to the same content on speakers.

It also makes me wonder how external control of Ace Ultra (via the API, mcp, 3rd party apps) will handle requests to group with the Ace Ultra.

 


I hope this helps!

Thank you.

Hmmm….this is what I’m understanding form ​@Corry P’s comments which are my uninformed (or yet to be tested ) thoughts as well:

  1. The Ace Ultra cannot be configured as a room the same as with a Sonos speaker
  2. The Ace Ultra becomes a pseudo-room (or room if you prefer) when it pulls content from a speaker. It also affects the 32 max units limit
  3. The Ace Ultra pulling content from a speaker within a group effectively causes the group to disband. Which would logically stop the music on the other speakers (I guess 🤔)
  4. A group affected by #3 remains disbanded even after content is released by the Ace Ultra to another speaker or being powered down
  5. It’s unknown (as I interpret ​@Corry P ‘s comment) that when releasing content back (due to the actions caused by the Arc Ultra in #3) it may or may not send the audio to the original speaker in the group from which it was taken
  6. The Sonos App (referencing a broken group) gives the user more latitude to direct where the audio will go upon release versus using the Content Key (i.e. a designated speaker). At that point the user can reassemble the group.

The following comment is my opinion and not that of ​@Corry P and posses a lot of what if’s 

  • As the Ace Ultra is not a room; in the normal sense of Sonos-speak, it cannot be grouped with other speakers. That makes sense to me because why would a user send content to the Ace Ultra and then want to group with other speakers. The only remote possibility I can see for such a use case is that the user of the Ace Ultra is outside the home (still in Wi-Fi range) and wants others inside to enjoy the same content. Now that’s a stretch 🤔

So if ​@Corry P wants to chime-in again...that’s very much appreciated 😊

Correct, though the last part must be done manually in the Sonos app.

You didn’t say that Ace Ultra can be grouped with other speakers while it’s linked.

I didn’t, and it wasn’t explicitly stated in the information I was given, but that’s the impression I’m under.

I can see why that’s not really an important use case for a lot of people, but like is the case for TV swap feature, people will want to listen to headphones while others are listening to the same content on speakers.

I presume market research has been done on this, but I know nothing of it, or the results. Maybe it’s just not currently technically viable.

It also makes me wonder how external control of Ace Ultra (via the API, mcp, 3rd party apps) will handle requests to group with the Ace Ultra.

I would assume it would fail, but again, it was not explicitly stated.

I hope this helps!

Thank you.

You’re very welcome!

  1. Correct.
  2. Correct.
  3. Correct - I think it’s assumed that when headphones get involved, silence is wanted elsewhere.
  4. Correct.
  5. I presume you meant “Ace Ultra”? It depends on the Sonos Fabric and determined positioning, and the method used; the use of the Content Key will send the audio to the nearest compatible speaker, whereas the use of the Sonos app can send it anywhere.
  6. Yes. No mention was made of the Group Coordinator, so perhaps behaviour will differ if the host of the Link is the GC, or not. I don’t know.

A Portable would make more sense in that scenario, I think. Perhaps those with hearing difficulties would want to be able to crank the volume on headphones without having playback being too loud for others listening to the same content while in the same room, but maybe a hearing aid would be recommended in such situations? I haven’t heard anything along these lines.

I hope this helps.

It's still not clear to me. Once I've linked the Ace Ultra to my Era 100 do I need to stream music from my library to the Era 100 and then transfer it to the Ace Ultra? Or can I stream it directly to my Ace Ultra? Another question: (just to make sure) the linking process needs to be done only the first time? Or do I need to link every time I want to use the Ace Ultra?

Short Answer…

As I understand it the linking process requires the target speaker to be actively streaming music before the Ace Ultra can interact with it. I could be wrong but that’s my understanding at the moment.

It is answered in the answer to this thread.

 

Can it play independently via the app, or does content need to be on a speaker first?

Content can be played to Ace Ultra via the Sonos app without being played on a speaker first, but the Link must be made with a compatible speaker before Ace Ultra will show in the app.

 

It was also confirmed elsewhere, headphone linking process only has to be completed once to add Ace Ultra to the Sonos system.

Linking is a fine feature, don't get me wrong. But it seems in and of itself to have relatively limited utility. My personal use would be limited to pulling active music from my surround system into the headphones. Then transferring to another speaker elsewhere isn't something I personally would do. Hyping that aspect as they did at roll out seems excessive but who am I to judge.

And if it can't carry spatial music even less value.
