Switch AirPods between iPod touch and other devices
When your other iOS and iPadOS devices are signed in with the same Apple ID as your iPod touch, your AirPods seamlessly connect to whichever device you’re listening to. (On supported AirPods and Beats headphones; iOS 14, iPadOS 14, or later required; iOS 14.3, iPadOS 14.3, or later required for AirPods Max.)
For example, if you’re listening to your iPad with AirPods but you want to listen to your iPod touch instead, start playing music, a podcast, or other audio on your iPod touch—your AirPods switch to iPod touch. Your AirPods also switch to iPod touch when you make or answer a call on iPod touch.
Switch AirPods back to your iPod touch
If your AirPods switch from your iPod touch to another device but you want them to stay connected to your iPod touch, tap 
(in the “Moved to” notice at the top of the iPod touch screen).
To stop AirPods from automatically switching between devices, go to Settings 
> Bluetooth, tap 
next to the name of your AirPods, tap Connect to This iPod, then tap When Last Connected to This iPod.
