iPhone - stream with Airplay
The best way to stream with Airplay is to first start to play music on your iPhone using any of your music apps, pod casts apps or radio apps or music streaming apps (like iTunes , Spotify, Tidal, Qobuz, Pandora etc.), then go to the iPhone’s Airplay menu.
This is the procedure to stream with Airplay:
On the iPhone you will find the menu by sliding your finger from the top right to the bottom of the home screen (for older iPhones instead slide from the bottom to the top).
Then you will see that the iPhone itself and the player are available in the list of Airplay receivers. Click on player and the connection is set up.
Airplay is supported by all Apple iOS devices, but there are also Airplay apps available for Windows and Android that you can download. Check out Google. iTunes uses Airplay on computers as well and it can be installed on your Windows or Linux computer and even on Android devices.
Bluetooth works too
It is really easy to stream with Bluetooth. As always when you stream, you control every aspect of listening with the app, like setting the volume, play/pause, next and so on.
The Network Music Streamer supports Bluetooth 5.0 and that version is supported by almost all iPhones around. With this version comes a wider range and increased transfer capacity which improves sound quality up to be like CDs. Bluetooth is backwards compatible, so you can use older iPhones like iPhone 5, but they might not always be able to benefit of these latest features.
... or stream your Spotify app, the streamer is integrated with the Spotify app so you can choose Player as an device within the Spotify app. That requires a paid premium account. If you only have the free basic Spotify account - stream Airplay or Bluetooth!
