I just got an 8+ coming from a 6, so this is my first experience with a headphone jack-less iPhone. I was trying out the little adapter dongle that comes bundled and it seems that it doesn't work when used with Apple earbuds (non-lightning ones, obviously). Is it just my adapter, or is this normal? I've tried with 3 different sets. It's worked with every non-Apple earphones I've used though.
