And don't work with the Mac Sonos app either?
And/or don't work by simply being connected to HDMI (in home theater setups)
Are you trying to imply that there are "many" that only use the app? If so, which products? If it is OLD Sonos products, I think they still lean on the S1 app, which is- best I know- still as it was before the new S2 replacement app took over with newer Sonos products.
Update: you made me curious so I did some searching and found
this Google Spreadsheet which is some guys attempt to summarize ALL Sonos products and their features. There IS an Airplay column showing whether they support Airplay or not.
Just eyeballing the Airplay column, it appears that "many"
DO support Airplay. Notables...
Older "AMP" products from 2015 and back, latest Amp does. Amp is not a speaker but basically a little receiver-like box to power "dumb" speakers.
Similarly, "PORT" is the same: latest does, older version from 2015 back do not. Port is an ampless AMP product, sort of like an AppleTV for audio only. The big benefit with it is access to all of the many
Sonos music services- including
Apple Music- and Sonos' own Radio channels that are then playable on any "dumb" speaker setup... like how many of us sometimes use AppleTV as a music jukebox source.
Nobody in 2025 are likely buying 2015 or older Sonos hardware. If they buy the versions available since 2015 versions- whether AMP or PORT, they have Airplay built in.
None of the Subwoofer generations- including the latest gen for sale now- support Airplay... presumably because it would make no sense to Airplay music to only a subwoofer. Subs connect to
other Sonos speakers like Arc and Arc feeds Subs audio suitable for Subs. Soundbars from Sonos do Airplay, so Airplay to any of the soundbars then propagates the deep bass to Subs linked to the bar.
Sonos Net products do not support Airplay, but their role is basically wifi signal extender to wirelessly connect Sonos stuff too far from wifi routers. Whatever speakers are connected to Sonos Net generally do support Airplay and thus anyone leaning on Sonos Net and wanting to Airplay do by choosing the connected speakers, not this device.
The latest new products- ACE (headphones) and Arc Ultra- both support Airplay.
I think that is everything. Maybe I'm missing a product or two.
