Hello _rOxyAnimAldoon9,

Thank you for reaching out to Apple Support Communities, and we'll be happy to help in any way we can.

To clarify, are you referring to having issues with multiple iPod devices connecting to your Mac, or are you having an issue using AirPods headphones? If the issue is with an iPod and your Mac, start with these steps: If your computer doesn't recognize your iPhone or iPad - Apple Support

On the other hand, if you're having issues with connecting your AirPods, try the steps here to see if the reset resolves the issue: How to reset your AirPods and AirPods Pro - Apple Support

"You might need to reset your AirPods if they won't charge, or to fix a different issue.

1. Put your AirPods in their charging case, and close the lid.
2. Wait 30 seconds.
3. Open the lid of your charging case, and put your AirPods in your ears.
4. Go to Settings > Bluetooth. Or go to Settings > [your AirPods].

• If your AirPods appear there as connected, tap the More Info button  next to your AirPods, tap Forget This Device, then tap again to confirm.
• If your AirPods don't appear there, continue to the next step. 

1. Put your AirPods in their charging case, and keep the lid open. 
2. Press and hold the setup button on the back of the case for about 15 seconds, until the status light on the front of the case flashes amber, then white.*
3. 
4. Reconnect your AirPods: With your AirPods in their charging case and the lid open, place your AirPods close to your iPhone or iPad. Follow the steps on your device's screen.

AirPods can be associated with one Apple ID. If you want to use AirPods (3rd generation) or AirPods Pro (1st or 2nd generation) that someone else has used, they first need to remove the AirPods from their Apple ID.

* When you reset your AirPods, the settings for your AirPods also reset. You can change your settings again."

We hope this helps.

Cheers!
