Enter the serial number in this link --> Check Your Service and Support Coverage - Apple Support - https://checkcoverage.apple.com/

Does it find them? If yes then at least the serial number is real, but I guess a good fake pair would use a real serial number. The only real way to tell is to only buy them from an Apple authorized retailer. --> https://locate.apple.com/
