Very disappointed to find out that because the way Apple designed the input for the headphones on the iPhone, most aftermarket headphones won't work. My $40 dollar phillips headphones are now worthless, great....The only phones that will work are those with a straight plastic piece at the end, the ones with a 90 degree angle for the plug will not go all the way into the jack on the iPhone. For a 600 dollar phone there sure seems to be a lot of issues increasing by the day....
