The Iphone has been out for years now and still there is no fix to this problem. If you use a2dp headset, all alerts other than a phone call come through a2dp, the problem is there is some sort of wake up delay so you miss the alert sound. This happens on all a2dp headsets that I know of connected to Iphone. Some sounds may make it through to the headset but not the default ones. Its the same issue when using Navigation software, you end up missing the first few words everytime. There has to be a fix for this, even if all apple needs to do is change the notifications so that they don't work through a2dp and work the same as phone calls. Does anyone know of a fix that I am missing?
