Has anyone else experienced sound quality problems with continuity calls made on a mac through a connected iPhone? On TELEPHONE calls made on my 2013 iMac through a connected iphone, the other callers always report that I sound terrible. They say it sounds like I am in a cave and that I sound extremely muffled, to the point where it is hard to understand me. I can hear them perfectly, though. If I make a FaceTime call through the mac, the sound quality on both ends is spectacular - so I don't think its an issue with the built in mic on the mac. Anyone else experienced this? Any ideas what may be causing this?
