Multi-room audio has become a core part of modern home comfort. People expect smooth transitions between rooms, instant control from a phone, synchronized playback, and compatibility with streaming services. Three major technologies dominate this space: AirPlay 2, Chromecast, and Spotify Connect. Each operates differently, interacts with devices in a specific way, and influences how multi-room sound behaves in daily life.

This guide explains how these technologies distribute audio, how stable they are in real homes, how they handle synchronization, and what makes each one stand out for different usage styles. Alongside full explanations, the guide includes a detailed comparison of ten multi-room speakers and audio streamers with prices, strengths, weaknesses, and user impressions.
