@arjayesspeaYes you can get applecare you just need to buy it direct from Apple:
https://www.apple.com/uk/support/products/headphones/Please read the notes carefully, also note AppleCare doesnt cover loss just hardware support..
To cover loss you need to look at seperate insurance such as gadget insurance.
This is not customer services and we dont have access to your account
