My AirPod is in my house but I can't find it

To attempt to find lost AirPods, the following must be true:

• Find My iPhone must have been enabled BEFORE they were lost.
• The AirPods are within range of your devices (iOS or macOS). Alternatively, they would need to be near any Apple device that the user has enabled "Find My Network" on.
• They are not in their charging case.
• They are still charged.
• The AirPods have not been reset.
