You got iPod Nano 7th gen?
Yes..
But i have found a solution easier that worked for me.. i found it on the apple discussions website:
After pairing the AirPods with the Nano
1) Go into settings on the iPod and turn off Bluetooth.
2) Press and hold the home and power button until the device turns off, and the apple logo comes up you can release both buttons
3) Open the music app on the iPod (I tried this with the podcast app, and it didn't work)
3) Start any song and turn the volume all the way up.
4) Go into settings and turn on the Bluetooth and connect the AirPods (this process can be accomplished without the AirPod's charging case)
5) If it worked, the AirPods will start playing at a really loud volume so be prepared.
