I agree the port for the headphone is in a terrible spot which I imagine has something to do with weatherproofing and the idea that most won't use it. I don't know about the rubber cover and wouldn't try to pull it out or you may play hell getting it back in without opening the case. There may be a male headphone jack that is 90 degree and a lower profile you can find or you might be able to make an adapter for the controller mounting plug that fits into the shaft that will move it up a bit to clear the hand , however that plug is always going to be hanging down by the hand.
