I know this might be a me problem but…
The Sonos ace is ridiculously loud! Just test it out, play music on full without it on your head and it's like a speaker!
I always have it turned down low but find myself creeping the volume up when a good song comes on or I want to hear more bass, and then I take them off and they are really loud to the point where I wonder if they are damaging my ears.
Is there no way to limit the volume like we can on other Sonos speakers? Or perhaps an android app that could help?
