First question I thought too. Waiting for the answer. 

Nope. Only one.

They should not sell them in pairs if this is true. It gives the impression that a couple can have a “cinematic“ experience while the kids sleep.  

The product page doesn’t seem to agree with this thread: “Quietly share an immersive home theater experience with someone when you swap TV audio from Sonos Arc.” (Shown when pair is selected)

An experience, certainly, but not likely of the cinematic kind

For me this feature is dealbreaker. I want to watch movies loudly with my wife without disturbing sleeping kids.

If it's possible, we want one arc = one or two ace and we will buy Why Sonos sale bundle of 2 aces? For gift?  for spare? 🧐 

I Agree would like to hook up at least to Sonos headphones with arc. For sleeping and loud kids. Also if you have guests 

Before purchasing I confirmed with Sonos customer support and was told “you can definitely pair 2 ace’s and 2 people can watch a movie together”  . But after receiving the aces and a few hours of trying to set them up, I contacted customer support again.  I was told that the original customer support response was incorrect and they agreed that the product description for the “pair of Aces” was misleading.  I am sending mine back, even though they sound great.  They said there is no known plans to add the ability to add a 2nd pair at this time. 

Plain misleading marketing. I am sending this through to the ACCC in Australia. Pull your socks up Sonos. This is plain creepy advertising and selling a pair and being deliberately fuzzy about connecting them together as a pair is MISLEADING ADVERTISING.

I’ll buy two when this is supported. It makes little sense why I can have a bunch of speakers playing all in sync - but we can’t get a pair of headphones working.

I don’t get it. 

Sonos themselves replied: 'Can my wife and I connect with the headphones and both listen to the TV at the same time?'  no,  it is one headphone at a time for this feature. 

That is from Sonos today (2 Sept 2024).

bummer ! 
 

this feature make sense and this is a deal breaker … Sonos if  you need selling more add this
