How do you find a missing airpod? It’s dead so I can’t use the find my app. Please help I’m freaking out.

Your only option is to use your eyes, backtrack your steps.

Follow the steps below,

1. Open FindMy App on your iPhone or iPad.
2. Head over to Devices section
3. Tap the AirPods name
4.  You can see the last location alongside time stamp.
5. Tap to get the exact location. 
6.  Traceback your steps and try to remember.

Still unable to locate AirPods?

Well you can reach out to Apple and pay for a single bud replacement. I have seen multiple AirPod single earbud listing on eBay, Amazon and other online stores.
