Hi: I'm not sure if this is a problem with my headphones, or the headphone jack. The earphones are dre dre beats(tours) which my friend just gave me to use, they sound fine when they're plugged into my captivate. But i realized if i wiggle the cable near where it enters the phones jack, my music player stops playing music. So for example, using doubleTwist, stock music player, youtube vids, when i wiggle the cord near the jack, the music/video stops, and I have to press the play button again. I tried a friends headphones(seinheisser) and wiggled it, and there was no issues. What should I do?
