Siri can't hear me when I talk on my headphones
Since updating to iOS 7 and thus 7.0.2 on my iPhone 4s, I have been listening to iTunes Radio, so I initiate the talk button on the ear buds to talk. I say things like "Play more like this" or anything and Siri doesn't respond. I look at the iPhone and the voice recognition wave line is flat when I talk. I have tried with 2 different pairs of headphones. I can however talk on a call through my ear buds and the other person can hear me and I can hear them. Please help
iPhone 4S, iOS 7.0.2
