Is it the headphones or the adaptor? iPhone 7+

I just bought a brand new pair of Skull Candy headphones and when I put them into the lightning adapter on my phone they keep cutting out, much like when you had a CD player back in the day without the anti-skip. It'll play for a split second and then dead silence or depending on the song it will be extremely reduced sound almost a whisper then I'll go back to normal and then It'll go back to being either silent or extremely reduced again. I just bought the headphones yesterday and the phone is about 2 months old. I contacted Apple support and they said it was the headphones. I am currently waiting for a reply from Skull Candy. They are the Ink'd headphones with a mic... anyone else have this problem?
