Headphones work as speakers (speakers) what should I do?

Question

Headphones

Hello, the headphones work as speakers or speakers, that is, that's the problem, I passed the test on YouTube for the sound of the headphones left to right, and the sound in the left and right earphones was in both ears. That is, if the sound should be only in the left earphone, I have it in both. I no longer know what to do, and reinstalled the firewood for sound, what should I do, tell me please? I might be used to it, but these are still headphones that are different from speakers.

3 contacts and 4 .
I don't think yours match.
And so there in the zoo there are still modifications of telephone headsets.
