I am looking for speakers, decent quality and nice looking that doesn't stand out too much. I want it on a bookshelf in the kitchen and another in the sitting room.

I want it to connect to a home server but also Spotify/streaming. And I'd like them to link together.

Basically I want the house listening experience to be seamless when going between different rooms, 2-4 speakers. Audiobooks and some music would be stored on a Nas and most music and podcasts would be Spotify.

I'd prefer to interact with it through my phone, Android if possible but not completely necessary.

In my head I imagine walking into a new room and tapping the speaker with my phone to switch to that speaker.

Is this a real thing?
