General

Your headphones may have been exposed to some sort of chemical that changed their color.
What color were they originally?

Where do you keep them? Is there anything blue near it?
Yes? Problem Solved.
No? It's Black Magic and you're next, leave your house immediately and head for the nearest galaxy

It may have been rubbing against your jeans, if they're a darker color.
I've seen shoes go blue from that too.

I don't wear jeans at home.

@Aileeny I am colorblind, but I asked my sister too, she said it was grayish. But the next day, it looked blue.

you probably put them in your jeans and the color rubbed off on them

@Xgo321 Parents won't let me get phone/camera.

Do you keep them in your jean pockets? The dye can rub off on them after awhile, especially if you washed them with it inside.

Maybe you're colorblind?

Take a pic?

@kizz123 well I'm not trolling. It's just all that I have. THere's nothing else that's blue except the jelly thing that goes in my ear and the wires

you can't expect a serious answer without trolls with the amount of information you gave us

Omg stop with the stupid trolls -.-

Blue earphones are a common item amongst the middle eastern cultures. Your earphones are infested with bacteria; be wary of putting them into your ear, as the rare, but serious disease Reye's syndrome may travel into your mucous membrane. Throw those out now.

Spend your last final moments with your family is all I have to say, may God be with you young soul...
