So I had my phone plugged in charging, headphones on while sitting on my couch and made a phone call. A couple minutes in to the conversation I started to move and I started getting shocked through my headphones. The person on the other side could also hear a shocking noise go through the phone. I yanked off my headphones and it stopped the shocking. I tried to replicate the issue with the headphones in my hand moving them around but no luck. An hour later or so I made another phone call and it started to shock me again. It started when the call was ringing and I yanked off the headset right away. After that call I used it with headphones on walking through my house making a call and nothing. Make an appointment with Apple??
