Doesn't work for more than a few seconds – EarMachine Review

I've tried this with iOS 6. Without headphones, it doesn't work at all, even though the description says it doesn't work WITH headphones on iOS 6. I've tried it with two different sets of headphones. For a second or two as I open the app or plug in the headphones, I get amplified sounds, but then it just goes dead. If I touch the screen to adjust the loudness (up or down), it will amplify while I'm adjusting, but stop as soon as I remove my finger. I'm also getting a sort of clicking sound that's unrelated to any sounds in the environment. Not sure what that's about. It's almost like it's trying to turn on every couple of seconds, but then dies right away.
