From the moment I discovered the headphone controls on my iPhone 4, I've been in love. The ability to answer calls; start, pause, and skip music; and change volume; all without removing my phone from my pocket remains one of my favorite features. My problem is that it's working only intermittently - inputs on the headphone buttons often don't register, and I'd like to fix this.
I've tried two different sets of earbuds, my old ones from the 4 and the new ones (God how I hate them) from my 5. The new ones didn't help, so I'm leaning toward a problem in the input jack on the phone. Is it likely it's just dirty or clogged with lint? Is there a reliable way to clean it out without damaging anything?

Please help.

I didn't find the right solution from the Internet.
