Earphone Shutting Galaxy GP off Problem

My entire family just got the Samsung Galaxy Grand Prime this weekend. The phone is great in all but it seems to not work with ear phones. When my dad plugged his earphones in his, it shut the phone off and turned it back on. I tried his ear phones on my phone and it did the same thing as soon as I plugged it in. My young brother left for college already, but he tested it with his ear phones and says it freezes his screen for a bit and then doesn't work. Has anyone had problems with using earphones on the Grand Prime? Any solutions?

I'm going to test more earphones and see what happens but I think I may have to go and take all these phones back. Really hope I don't have to since I'm not sure how I'll get my brother's back.
