HeOS is bluetooth only while Sonos is now bluetooth and WiFi.

WiFi is nice because I don't ever get connection issues or drops around the house. I have a few bluetooth speakers and they were bad at this. Just walking into the kitchen or bathroom caused the connection to drop.

Some other features I like: - Good range of sources, ticks the boxes for me - Spotify, Soundcloud and NAS - In clients premises I use HeOS 3 units, plug a USB stick full of tunes and it will connect to other HeOS units and play across all of them. - They have a decent solution for hooking up existing amps/floor standing speakers.

I own HEOS speakers, they are WiFi. For instance Denon AVR creates its own WiFi network that HEOS surrounds participate in, and the independent room speakers are all visible on the joined WiFi network as well. So, wired, Bluetooth, and WiFi.

Agree with grandparent comment, the HEOS speaker sound is fuller/richer, less reliance on Bose-style psychoacoustics.

Further, the Denon AVR with HEOS surrounds is the only receiver I know of supporting integrated amplifier for wired front speakers (separates) and WiFi wireless surrounds. I run Definitive ProMonitors and ProCenter for front, and Denon HEOS for surrounds.

(Note: Many receivers support wireless for other zones, I’m talking about mixing amped and wired for front with wireless for surrounds, and also ruling out “kits” where you can’t mix and match your own choice of speakers.)
