Iphone 6S - constantly pausing and replays while i'm walking.

 When I am walking, listening on my headphones, spotify constantly pauses and replays.  The app is up to date and I am running IOS 11.3.1.  This issue happened on two Iphone 6S, I thought my first phone was the issue because the screen was cracked.  Since then, I received a replacement phone and I am still having the same issue.

If you are using the same headphones this could be the source of the problem! I had the same issue and it resulted in being the glitch of the volume buttons.
