Sonos Ace Ultra as a room in the S2 app

It's still not clear to me.

I own 1 Era 100. I should link the Sonos Ace Ultra to my Era 100, then stream content to the Era 100, then swap the music that's playing on the Era 100 to my Ace Ultra, if I understand correctly.

So I can't setup the Ace Ultra in the Sonos app (without linking it to my Era 100) and stream music to it. Correct?

This is my understanding:

You have to set up the Ace Ultra in the app when you get it (like the current Ace) - this links it to your account and if like the current Ace, if memory serves me right, you need Bluetooth enabled on the device also. Once set up it will appear in the App when linked to a device via Bluetooth. Then with the new Ace Ultra, you can set music streaming on your Era 100 then swap the sound to the Ace Ultra headphones. This is something that cannot be done with the current Ace. That one only swaps TV sound with a compatible soundbar. I think this will be how it works…………………...  Someone can correct me if I am wrong. 

Think about it this way.

The music services are stored on the speaker. In order to play music on Ace Ultra from the Sonos app, you need a compatible player. If the compatible player is powered off, then the audio will stop. At least that’s my understanding from the support articles available.

 Close. I don't  think  the 'swap' is using Bluetooth.  Instead, it is likely using ultrasonic frequencies, so that can determine what sonos devices.   I think you initiate the swap by pressing a button on the headphones, like you do for TV swap, and the headphones will find the nearest room playing audio and 'steal' it.   If I understand  correctly,  you can then walk to another room and press the button again to swap the music to the new room as well.

I think there is an asterisk issue too, the Five and Play, are they really able to link when used as surrounds?

Or do they need an asterisk like the other similar speakers?

The web folks need to work on accuracy and consistency or they are going to generate unhappy customers and returned product.

If you're right (maybe a Sonos rep could shed some light on this) I will not purchase a Sonos Ace Ultra. I just want to add the Ace Ultra to my system and stream music to it (like I do to any Sonos item in  my household). I dont want to have to link anything and swap music from A to B before I can listen to it.

In order to add Ace Ultra to your system, you have to link it. This appears to be a one off process, like setting up TV Audio Swap is currently on Ace. You can then select Ace Ultra in the System tab to play directly to them from the support page you have previously quoted.

1. You can select content to play directly to your headphones by navigating to the System tab and selecting your Sonos Ace Ultra.
2. Once selected, navigate to the Home or Search tabs to select content.

Uhhh, the Sonos Five is in the list of players.  Also, the Line-In used by the turntable is a Sonos source and can be played on any Sonos player.  So you would choose the Line-In source on any player from that list (including the Fives), link the Ace Ultra to that player, and drop the needle.

Lol - see my other replies and you will see there is a discrepancy between the list of players on the Shop site compared to the list of players on the info page from Mr T’s link. The Five appears in one list but not the other. I was only looking at the info page link where it is not listed. Sonos just  need to update the lists so that they match!

I see that.  Even if the Five is not supposed to be on the list, you can still use the Line-In on the Fives as a source in any other Ace Ultra compatible unit.
