Can the previous owner track AirPods location after reset ?

You must reset them by opening the AirPods and holding the pairing button on the back for 10-15 seconds. You'll know when they are done because the light on the AirPods will flash amber for about 3 seconds. The last owner also must go into Find My and under the devices list, click on the AirPods and press "Remove this device."

When you connected the AirPods, if the name was "(AirPods Name) - Find My" then the last owner did not remove the AirPods from Find My and they can potentially be tracked. Keep in mind though, that your iPhone will alert you if you are being followed (or if you are carrying) by AirPods that are being tracked by someone else.

If they're reset correctly and not paired to the previous'ses owners Apple ID they would not be able to track them
