Well, I think I'm having the issue with notification sounds on my iPhone 6+ that Harry was talking about. If I'm near my MacBook Pro when I get a text message I can hear the ping notification on the MacBook Pro. It is really loud so I don't know if my iPhone 6+ also pings or not. However, yesterday I was in another room and during the day I received three text messages, none of which did I hear a ping. I only discovered them later when doing something else on the phone. I keep my iPhone 6+ in an Otterbox Defender case and use the belt holster. But in the past this has never been an issue with hearing the notifications, even when listening to the TV.
