KS8.0 play iTunes with Gen3 Apple Watch with GPS & cellular


I know I can play iTunes via my Apple phone. I also know I can play iTunes when paired to my Apple Gen1 watch as long as I have my phone turned on and paired.

My question is can an Apple Watch Gen3 with GPS & cellular play iTunes thru the KS8.0 HA’s without the phone?

If anybody is doing this I’d like to know.
