TV Audio Swap only works for “tv audio” (ie. audio received via HDMI ARC/eARC or optical) from a compatible Sonos soundbar.

You are not able to swap a music stream from any Sonos device to Ace.

In order to hear your turntable on Ace, you could connect your turntable to a Bluetooth transmitter, then connect Ace to the BT TX.

This product is getting less interesting by the minute Thanks for the answer

Not the Ace’s fault really. If you wanted to listen to any turntable on any Bluetooth headphones you’d need a Bluetooth transmitter somewhere in the chain.

You should see the Ace simply as Bluetooth headphones that can also access the TV’s sound via a Sonos soundbar. That is it. That’s all they were ever marketed to be. 

There was certainly an expectation from many users that Ace would be just another “room” in the app before the actual tech specs/ability were confirmed.

That’s true. And it disappointed many. But I suppose my point is that no-one buying Ace is being hoodwinked that they perform any other function that those described.

So when they are cited as getting less interesting by the minute, it suggests a degree of assumption was employed before they were bought.

I guess the expectations were so high because Sonos was basically synonymous for allowing to "let the sound follow you through every room", well it was their big mantra for a long time and so with the Ace there is basically none of that functionality available. The Ace essentially acts as a glorified and slightly pimped (Audio Swap) Bluetooth headphone, with a very hefty price tag attached to it. It sits at a very strange place, at least for me, inside the whole Sonos ecosystem.

I certainly held those expectations before Sonos announced and began marketing the Ace headphones. Since the announcement, however, it was clear that these were a different type of device from their normal speakers, and their marketing has backed that up. I still own and use a set of Ace headphones, they’re better than the older set of BOSE headphones I have. 

I have a U-turn tt connected via Line-in to an era 100 speaker. I have a gen 2 beam which plays music from the tt via the connected era 100 (as well as 2 other era 100 and a Move). Will Ace connect to one of these? 

No, as per the answer already stated for this thread.

No - the Ace headphones receive music via Bluetooth. The Era 100 and the Move also receive audio by Bluetooth - neither speaker sends audio by Bluetooth so the Ace cannot get music this way from Sonos speakers.

The only way the Ace gets any audio from a Sonos speaker is when TV audio to a Sonos soundbar is swapped to be sent instead to the Ace, by WiFi. 

The definitive way to look at it is: if Sony, or Beats, or Samsung, or Sennheiser headphones can’t do it, then nor can the Ace. Unless you’re watching TV...
