Plug them in fully - fully, note. Better?

Welcome to Android Central! Do the headphones work on another device? Can you test another pair of headphones on the phone in question?

Are the headphones designed for iPhones only? Some wired headphones have both iOS and Android models, and they aren't interchangeable.
