Left AirPod not charging

It is very possible there is something in the area where the left AirPod goes into the case that is causing it not to make contact for charging. Have you looked inside the case? If you cannot see anything, then make an appointment at the Genius Bar of the nearest Apple Store to have them looked at by Apple. They will outline your options from there.

Left and/or Airpod Not Working after re-pairing, toggling various settings, Apple TV not seeing them?

I tried everything. From multiple forums. When it hit me, why were there a lot of ppl with this same problem but not anywhere near the # of ppl who are obviously are buying them? Time is the answer, my friend, Time.

First, Airpods get dirty. Thankfully, they are easy to clean with their porcelain-ish finish. But how about the case receptors? They obviously collect dirt, dust, ear wax, pizza crumbs, etc. So, I tried the only thing that has worked: Clean the Airpod Case and the stems of the Airpods, themselves.

Follow these steps:

1) Take the Airpods out of the case.

2) Grab a Q-tip.

3) Get your wife's bottle of nail polish remover (or your own - acetone). Side note: I originally thought of rubbing alcohol but didn't none nearby.

4) Dip 1 Q-Tip into acetone and then into the bottom of each of the two holes in the Airpod case and twist it in there for a few seconds).

5. Take same Q-Tip and clean the bottom of the stems where the Airpod comes into contact at the bottom of the hole. Let dry for 30 seconds.

And within 1 min....voila'! iPhone did the animation (which had grown erratic), appeared as a selectable audio output on my Apple TV., etc. etc. etc.

Hope this helps as I love these things too much to be buying or waiting in line into exchange them.
