The apple website hasn't updated their earpod compatibility since early 2013. I just bought a pair of new EarPods and it does not work with the iphone 4 running ios 6, but works on iphone 5 running ios 7. The old EarPods that came with the iphone 5 works with iphone 4. Not working as in volume up down not working, play/pause button not working, and getting sound through many apps with problem. I never knew the same brand earphones would be so problematic. Anybody having the same issues?
