The headphone jack back/forth issue. I went bluetooth last Xmas and wouldn't go back! I HATED the wire getting caught on everything! Knobs on drawers and they YANK out of my ear! HATED IT! Plus I get days out of my headset and charge it for about 2hrs. and it's ready to go. My EarPods are now a backup in case I want to not wait for the bluetooth to charge. But I went bluetooth and won't be going back.
