I’m returning g my Ace’s because of my increasing disappointment with Sonos, due to their lack a care for the customers and serious fall in quality. Now since the last update the hard reset in the ace no longer works. I’ve done the process multiple times as I let other Sonos users test them. Now, nothing. The light just stays orange. I guess this is just par for the course. 
The consensus from myself and those that tested them is “meh”. Muddy veiled sound, gimmicks that don’t justify the price, no amp support for tv swap, underwhelming and seemingly directional noise cancellation… seemingly good build quality. 
 

I used to be a huge Sonos fan boy. 
RIP Sonos.
