Setting up a Chromecast speaker group

[RedJeep2023]

Wasn't really sure where to post this.
I currently have a pro connected to my home theater system which is my primary listening Room. I'm using Wi-Fi and streaming from Qobuz.

I do not have an iPhone. I'm Android.

I'm considering hooking up my mini to my old Bose Wave radio in my bedroom. It does have RCA jacks so I think it's possible.
My question is... can I sync these two devices so that when I walk from my living room and into my bedroom the same track is playing?
What I want to avoid is having to connect my Wii Pro (in the living room) with my phone via Bluetooth and sacrifice sound quality. TIA

I think the answer is yes but it has nothing to do with Chromecast.
The WiiM Mini has a 3.5mm jack line out that can be used with a 3.5mm jack to 2 x RCA cable.
You will sync the Pro and Mini inside the WiM Home App.

THX guys. I guess the reason I mentioned Chromecast was because the only thing I could find on this was how to do it with airplay which as I understand it only works for iPhones and I wanted to be clear that I do not have an iPhone so AirPlay would not work in my case.
