Bluetooth audio is everywhere. It's built into speakers, soundbars, TVs, and kitchen radios. It's easy to use and it works. But if you've ever noticed the music cutting out when you walk to another room, had your audio hijack itself when someone else's phone got too close, or simply wanted music playing in more than one room at once — you've hit Bluetooth's limits.

WiFi audio — specifically Apple's AirPlay — is a fundamentally better way to stream music around the home. Here's why it's different, and what kind of setup makes it possible.

The fundamental difference

Bluetooth creates a direct wireless connection between your phone and a speaker. That's it — one phone, one speaker, at a range of roughly 10 metres with walls in between. The audio data travels from your phone to the speaker, which means your phone has to stay within range, and your phone's battery is doing all the work of maintaining the connection.

WiFi audio works completely differently. When you stream music via AirPlay, your phone sends the audio to your WiFi network, and the network delivers it to speakers anywhere in the house. Once the stream is started, your phone is no longer involved — the speaker is pulling the audio directly from your music service. You can put your phone in your pocket, walk to the other end of the property, even leave the house — and the music keeps playing perfectly.

What this means in practice

No range limits

AirPlay works wherever your WiFi reaches. A speaker in a poolside cabana at the back of a large property can receive the same audio as a speaker in the kitchen — without any dropouts, without any degradation, without you needing to be anywhere near it. The range of your WiFi network is the range of your audio system.

Multiple rooms, simultaneously

AirPlay lets you stream music to multiple speakers at the same time, all in sync. Music playing in the kitchen, living room, outdoor entertaining area, and master bedroom simultaneously — all perfectly synchronised. This simply isn't possible with standard Bluetooth.

Better audio quality

Bluetooth compresses audio to transmit it wirelessly, which has an audible impact on quality at higher volumes. AirPlay streams at full CD quality (lossless), so what you hear is what was recorded. For anyone with a decent speaker system, this difference is noticeable.

No more "who connected to the speaker?"

Anyone who has had a dinner party knows the Bluetooth speaker problem: a guest's phone connects automatically because it remembered the speaker from last time, and suddenly the music changes. With AirPlay, control stays with whoever started the stream — guests can request songs but can't accidentally take over.

The John Sandilands experience: We recently modernised an audio system for a home in Burradoo, replacing an ageing multi-room system with AirPlay-enabled speakers throughout the house. Now guests simply connect to the WiFi network and can stream from their own music apps to any room. No pairing, no codes, no frustration — it just works. That's exactly what whole-home audio should feel like.

What you need for AirPlay to work well

The quality of your WiFi network matters. AirPlay audio is reliable when your WiFi is reliable — but a network with dead spots, dropouts, or congestion will result in audio interruptions. This is why proper whole-home WiFi is the foundation of a good home audio setup.

AirPlay-compatible speakers are available from a range of brands — Sonos, Denon HEOS, and various others support it natively. Apple HomePod speakers are another excellent option. Many modern amplifiers and receivers also include AirPlay support, so you may be able to use your existing speakers with an AirPlay-compatible amp.

💡 If you're planning a home renovation or building a new home, it's worth thinking about audio zoning at the same time as your network design. Getting the cabling and speaker placement right during construction costs a fraction of what it costs to retrofit later.
