Hey Folks, I read a lot of posts last year complaining about the 6 and 6+ having low earpiece volume when you talk on the phone. It seemed like Apple listened and significantly boosted the earpiece volume on the S+ at least. But did they do it at the cost of causing some "overloading" or "crackling" when you turn the volume up past 75%? I have that very issue now. I can hear well even while walking down a busy street but noted some intermittent crackling as though the earpiece speaker is blown or defective. If I turn the volume down to blow 60% or so, it decreased a lot if not completely goes away. Oh yeah, I played with the Hearing Aid feature and it did STOP the crackling even at 100% volume but the audio is muffled lack treble and Noise Cancellation is disabled. And ideas, folks? Thanks.
