AirPods Pro Ear Tip Fit Test fail (seal is actually good on both sides)

Ear tip test for me got passes on both ears straight away and multiple times with both medium and large tips on first couple days after I got them

However, since then, the left consistently fails the test when I check despite the left bud being just as sealed as the right one with identical sound as the right whether ANC/transparency/off selected. Medium and large tips have same result - left fails the tip test every time. Tried un-pairing from iPhone, resetting the pods the setting up again, but no different.

My thoughts are a glitch in the code for the ear tip test that goes wrong after a few days and a future release will solve.

Contacted Apple Support yesterday who had agreed they have seen reports of this already. They got me to send them a full set of logs from iPhone for analysis then will get back to me once their engineering team takes a look.

Very happy with product generally and no problem with function or sound quality.

But something to keep an eye on...

iPhone XS Max, iOS 13

I can confirm the Loctite Fun-Tak solution worked for me. I now have the good seal on Fit Test for first time since week 1 of owning them. I had the same deal as a lot of people on here - the fit test worked for the first few weeks, then failing each time I've tried since then. (I've had them about 3 or 4 months now). I picked up some Loctite Fun-Tak and went to work.


It was a trial and error, as I didn't know how much I had to press and pull, I used the magnifier on iPhone to check my progress. I finally ended up with a 100% clean sensor screen, and the fit test started working. What I found best was covering the sensor with the putty, apply some pressure, and quickly rip it off (like a stuck band-aid). I also did some rapid-fire dabbing as well. A combination of those techniques cleared the crud out. (note: don't press so hard that you get putty stuck in the grooves... I did that at first but was able to get it back out).


For a comparison, like I mentioned above, I used the Magnifier tool on iPhone to view a "before" and "after". Note that you can't see any of this with the naked eye, you really need to magnify it. Here's a before and after. (The "before" looks pretty gross - the grooves are filled with dead skin, oil, wax, whatever it is). The "after" shows them very clean. I shower every day and wash my ears out just like everybody else, but this shows it may be time to start Q-Tipping each day as well, to further my effort in keeping the AirPods clean.


Before: Note the crud stuck in the sensor grooves/dimples, and also around the perimeter:




After: Note the entire sensor is clean:




For those of you doing the "suck out the crud" method, after seeing this you may think twice about that now :D

Seems to me that they are very much handle with care; especially if hands wet at all or sweaty.

I’m beginning to wonder if the moment mine went was a day at the gym when someone went to ask me something, I merely took out the left one to listen then when fitting the left back in, a slightly sweaty finger may have accidentally ‘pushed’ some sweat into the grill killing the left external microphone.

I didn’t notice at the time as I think I maybe have had ANC off.

If so, that grill is a massive and terminal weak spot.

Be careful in similar circumstances is my thoughts on it.
