I just brought home a new iPhone 6s purchased directly from apple. I'm having a strange audio issue that effects both ends of a call. On my end people sound as if they are speaking in slow motion, sound is about half of original speed with a lot of static. At the other end of the call I'm told I sound like an alien munchkin. So I called my own home phone from my iphone and left a message for myself and sure enough I do sound like an alien Munchkin! LOL. My location is downtown Toronto and I'm on a monthly unlimited voice plan.
I contacted Apple support and they had me do a factory reset and that didn't help. Problem is still there. The ticket is still open and the next step would be to replace the phone. Before I do that I just wanted to check here to see if anyone has experienced this type of issue with an iphone. I did a search before posting and nothing in the search results resembled my issue.
