What is the compatibility like with the i series of these headphones (with the volume buttons)? I know it won't natively work but if I have a third party app, such as Headset Droid or Jay's, will the volume buttons work? Before I go and spend the $80-100 on these I'd like to know if these or other similar headphones work with the volume buttons. I know the apps are free but the headphones unfortunately, are not. Haha.
