Over the summer, I had a pair of AP2 and I took them back from my daughter because she upgraded to AP Pros. One day I started using them and one earbud was muffled and the sound was low. I thought that was odd because there is no visual damage of it. It still charges and holds a charge. I tried all of the tricks including cleaning, adjusting the sound, etc.... and nothing seemed to fix it.
A month or two ago, I took them to Apple and the guy ran a diagnostic test and told me there is something wrong with both earbuds. He didn't go into detail of the problem but the case is fine.
The conclusion was I had to replace them with new ones. I still don't know what happen to them. My daughter could have dropped them for all I know.
