How do I know if the AirPods Pro are original?

Hi

No. this is not 100% guarantee.

Go to Bluetooth settings of your AirPods.

tap "i". then go to section with serial number. Tap "serial number". if it's clickable and shows you three different numbers, that's original.

Firmware version line is clickable as well. tap it. it must show version for airpods and for case.

check the version of your firmware with the latest at official site.

Fakes now are so real that apple's site shows they authenticity. currently go through the process I mentioned.

this is 99.9% guarantee now.

Hey so mine are pretty much the same as his but when I put in the serial number that’s on the box, it’s says “We’re sorry, but this is a serial number for a product that has been replaced. Please check your information and re-enter your serial number. If your information is correct, you may need to contact us.” I’m just wondering if they’re authentic.

Yes, this website is from Apple.

That's normal, Apple has offices in Ireland.
