Problem with the headphone jack in my iPhone 6?

Whenever I'm wearing my headphone while walking (or basically any type of fast movement) the music will get all staticy for a few seconds. At first I thought my Apple headphones were wearing out but I got a new pair and the same thing is happening. Is there any way I can take care of this at home rather than sending it in to get fixed?

The socket is dirty. Get a pipe cleaner and Windex. Shut off the phone. BARELY barely dampen the end of the pipe cleaner with Windex. Clean our the socket gently byt thoroughly, as if a baby's ear. Clean the PLUG on your headphones, too. Let everything dry. Turn on phone, insert pug into socket. Better? Try spinning the plug around once or twice. Better? Might need more than one cleaning. There's well over $100K of music equipment in this house (two professional music studios), and every so often, I get out the cleaning stuff, and line up all the similar devices, and clean them ALL -since we often swap the headphones and earbuds from one to another. I put on some music, relax, and take my time - sure beats DRAM when something you need *right now* decides not to work. In an hour - I'm good for weeks or more. I'm similarly vigilant about cleaning digital devices, blowing out dust, backing up everything, updating all kinds of software, backing up all my DATA, checking al my digital and Net protection - the stuff that keeps me away from the crying and screaming HERE when people say they lost their phone, dropped their iPad, lost 5,000 pictures, and 10,000 songs - and of course - NEVER BACKED UP ANYTHING. Storage is CHEAP - loss is terrible. So start with just cleaning out dust and grit - then go after DIGITAL cleaning. Think of it as Jenny Craig (or Biggest Loser!) for your digital life.
