Very Weird Problem...

My iPhone has been working perfectly up until a few days ago when I started using the V-Moda Microphone headphones that I just purchased (which sound excellent btw). For some reason the text message tone does not play anymore! If I have the headphones plugged in I'll hear it threw them but when they are unplugged nothing plays. The ring tone alert works fine as does the E-mail alert. Any suggestions? I did restart it to no avail.


Edit: Just got an incoming call, I can't hear anything the other person says and they can't hear me! if I put it on speaker phone it works just fine. The headphones work as well to talk...
