Grab some heat shrink tubing and a couple of dongles, attach the dongle to your headphones with heat shrink tubing.
I'm liking my 7+ quite a bit, the camera is sweet.
The home button still feels strange, but I use an iPad quite a bit, so am always transitioning. I'm not unhappy, but it sure feels different.
Mine has the "whine" but I have to hold it against my ear to hear it.
3D Touch is still sort of odd, I don't use it much at all.
