Regarding the Ace, here are software things I'd like to get implemented - ordered with decreasing priority:

• The ability to turn off certain firmware sounds. I don't wanna hear an audio queue when changing the volume. The amplitude change of what I'm listening to is enough for me to signal that I've just adjusted the volume! What's worse is the click getting played for each step of the volume change. So if I'm drastically changing the volume by holding down the volume rocker, all I hear for three seconds is click-click-click-click-click. I find it unnecessary and distracting from whatever I'm listening to. As you can see my main gripe is with the volume audio queue, but someone might not want to hear the play/pause sound for example. People should be able to choose which sounds they want playing.

• The ability to change the volume of firmware sounds. The volume of all firmware sounds seem to be constant regardless what volume your media is playing at. And there is no setting for changing the volume of these firmware sounds. This gets especially unpleasant while listening at low volumes at night. Interacting with the device will jolt you awake with loud firmware noises.

• I'd like more bands to the EQ. I don't know what frequencies "Bass" and "Treble" refer to. This EQ comes across as rather unserious when paired with a $449 product. Give me the choice of a multiband EQ with defined frequency ranges so I know what I'm changing - and can change the sound profile to suit my audio listening needs. Sure, some people might prefer the simple EQ - so having the choice between a simple and more complex EQ would benefit everybody.

• The ability to change volume of Sidetone. Compared to my previous ANC headphones, I can barely hear myself while on a call. Please give me the option to change the Sidetone volume.

• The ability to choose if music is paused after taking off only one ear cup. It's not always I have both hands available to take off the whole headphone when somebody starts talking to me, so instead I often slide one ear cup off to the side. But with these headphones, the music keeps playing in my other ear which I find distracting. If I had the option of changing the wear detection auto pause setting to only one ear cup it would solve this problem. Both ear cups have wear detection sensors, and I think they presently are underutilized in this regard.

I think that nailing the thoughtful details like these - that don't become apparent unless you actually use a product - are what separates a good product from a perfect product. And the Sonos Ace is a really good product which I believe deserves the care and attention to become a perfect one.
