What linking multiple speakers actually does

Linking multiple Bluetooth speakers means connecting them to the same audio source — your phone, tablet, or computer — so they play the same sound at the same time. This is different from pairing, which is just connecting one speaker to one device. When speakers are linked, they act as a single system rather than individual devices.

Most phones and tablets cannot send Bluetooth audio to more than one speaker at once using standard Bluetooth. To link multiple speakers, you either use a feature built into the speakers themselves, or you use an app or setting on your device that was designed for this purpose. The method depends on what speakers you own and what device you are using.

Key Takeaways

  • Standard Bluetooth on phones and tablets only connects to one speaker at a time, so linking multiple speakers requires either a built-in speaker feature or a special app.
  • Some speaker brands like Sonos, Bose, and JBL have their own apps that let you group speakers together and control them from one place.
  • AirPlay (Apple devices) and Chromecast (Android devices) are built-in features that can send audio to multiple speakers without needing a separate app.
  • Linking speakers over WiFi usually gives you more control and better sound quality than using Bluetooth alone.
  • Once speakers are linked, you control the volume and playback from your device, and the speakers stay synced to each other.

Using your phone's built-in features to link speakers

If you own an iPhone or iPad, AirPlay is the easiest way to send audio to multiple speakers at once. Open any app that plays music or audio — Apple Music, Spotify, a podcast app, or YouTube. Look for the AirPlay icon, which looks like a triangle with sound waves coming from it. Tap it, and you will see a list of available speakers. You can select multiple speakers by tapping the checkbox next to each one. All selected speakers will then play the same audio in sync.

If you own an Android phone or tablet, Chromecast works the same way. Open your music or audio app and look for the Chromecast icon, which looks like a rectangle with curved lines in the corner. Tap it and select the speakers you want to use. Not all Android apps support Chromecast, so check whether your app has the icon before you buy speakers. Spotify, YouTube Music, and Google Play Music all support it.

Both AirPlay and Chromecast require your speakers to support these standards. Check the speaker's box or manual to see if it says "AirPlay compatible" or "Chromecast built-in". If it does, you can use your phone's built-in feature without downloading anything extra.

Using a speaker brand's own app to link speakers

Many speaker makers have their own apps that let you link their speakers together. Sonos speakers use the Sonos app, Bose speakers use the Bose Music app, and JBL speakers use the JBL Authentics app. These apps do more than just link speakers — they also let you control which room each speaker is in, set different volumes for different speakers, and sometimes play different music in different rooms.

To use a brand's app, read it from the App Store or Google Play, create an account, and add your speakers to the app one at a time. The app will walk you through connecting each speaker to your WiFi network. Once all speakers are added, you can group them together in the app and send audio to the whole group. This method usually works better than Bluetooth because the speakers talk to each other over WiFi instead of relying on your phone's Bluetooth range.

The downside is that you need speakers from the same brand to use this method. You cannot mix a Sonos speaker with a Bose speaker in the same group using their apps. If you want to link speakers from different brands, you will need to use AirPlay, Chromecast, or a different method.

Linking speakers over WiFi versus Bluetooth

When speakers are linked over WiFi, they stay connected even if you walk far away from them or your phone goes to sleep. Bluetooth speakers disconnect if you move too far away or if your phone's screen locks. WiFi linking also means the speakers can talk to each other directly, so they stay perfectly in sync. Bluetooth linking depends on your phone sending the signal to both speakers, which can cause slight delays or timing problems.

WiFi linking requires your speakers to be connected to the same WiFi network as your phone. If you are at home, this is usually not a problem. If you are at a place with a weak or unreliable WiFi network, Bluetooth might work better. Some speakers can do both — they connect over WiFi when possible and fall back to Bluetooth if WiFi is not available.

What happens when you link speakers

Once speakers are linked, they become one audio system. When you press play on your phone, all linked speakers start playing at the same time. When you adjust the volume, all speakers get louder or quieter together. If you pause the music, all speakers pause. You control everything from your phone, and the speakers stay synced without you having to do anything else.

Some apps and speaker systems let you set different volumes for different speakers even when they are linked. For example, you might want the speaker in your kitchen louder than the one in your bedroom. Check your speaker's app to see if this option is available. Most brand apps like Sonos and Bose allow per-speaker volume control, while AirPlay and Chromecast usually control all speakers at once.

Troubleshooting when speakers won't link

If your speakers are not linking, first check that both speakers are turned on and connected to power. Then make sure they are both connected to the same WiFi network if you are using WiFi linking, or that they are both in Bluetooth range of your phone. Restart both speakers by turning them off and back on, then try linking them again.

If you are using an app, make sure you have the latest version installed. Open your phone's app store, search for the speaker app, and check if an update is available. Close the app completely and open it again. If the speakers still will not link, check the speaker maker's website or the app's help section for troubleshooting steps specific to your model.

Sometimes the issue is that your phone does not support the linking method. For example, if you have an older Android phone without Chromecast support, you cannot use Chromecast to link speakers. In that case, use the speaker brand's app instead, or use a different device like a tablet or computer that does support the feature.

Frequently Asked Questions

Can I link speakers from different brands together?

Only if you use AirPlay (Apple devices) or Chromecast (Android devices). These are built into your phone and work with any speaker that supports them. Brand-specific apps like Sonos or Bose only work with speakers from that brand.

Do linked speakers have to be the same model?

No. As long as they support the same linking method — whether that is AirPlay, Chromecast, or a brand app — they can be different models from the same brand. You can link a Sonos Move with a Sonos One, for example.

Will linking speakers drain my phone's battery faster?

WiFi linking uses slightly more battery than playing audio through a single speaker, but the difference is small. Bluetooth linking uses more battery because your phone has to send the signal to multiple devices at once.

What if my speakers keep losing sync?

This usually happens with Bluetooth linking because the signal can be interrupted. Switch to WiFi linking if your speakers support it. If you are already using WiFi, restart both speakers and your phone, then link them again.

Can I use linked speakers with voice assistants like Alexa?

Yes, if your speakers have Alexa built in. You can ask Alexa to play music on multiple speakers at once, and Alexa will handle the linking for you. Check your speaker's manual to see if it has Alexa support.
