Is anyone else having iPhone 5 problems?

Everytime my earpods are plugged in, and playing music, the music all of a sudden stops in the middle of a song, or starts playing it faster. Sometimes it stops, and Siri randomly pops up. It happens most when i'm on YouTube. When i'm watching a video, the video will stop, music will start playing, stop, and Siri pops up. It's extremely annoying and it only happens when my earphones are plugged in. Has this happened to anyone else and how do you fix it?

On the ear pods there are 2 buttons and a microphone. Maybe your hitting the buttons by accident. Also Siri has a censor so when you put the phone up to your ear She will activate. Maybe somethings activating the censor.
