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 purchased a set of AirPods Pro on the day they became available in store. I personally had problems with them. The noise reduction seemed to work sometimes and just stop working and then start working again. Sometimes better in one ear than the other. I found the Ear Tip Fit Test and ran it. Both sides indicated failure. Long story short, I tried every possible combination of tip sizes and was never able to get both to pass the Ear Tip Fit Test. Left would pass and right would fail. I would adjust the right and then the right would pass and the left would fail. Out of frustration I took them into the Apple Store where I purchased them. They had me try the demo pair (which was pre-installed with medium tips on left and right). I paired the store demo AirPods Pro with my iPhone and placed them into my ear. They passed both left and right immediately. I switched to the small tips and tried again. Both sides passed immediately. I switched to the large ear tips and repeated the test. Both sides passed on the first try. I placed the medium demo tips onto my personal AirPods and tried the test 10 times. It failed every single time despite adjusting and pressing them into my ears between tries. At the end of the Genius session - the very nice Apple Store employee took a new pair off the shelf and exchanged them for my bad pair. It was clear that the original pair had some type of issue. If you are having trouble getting your AirPods Pros to pass the Ear Tip Fit Test, I would take them back and exchange them. They are probably defective. I am so happy that Apple fixed the problem as soon as I took it to them.

I exchanged mine at an Apple Store when I could not get a good seal. The new ones immediately gave a good seal. After about a week, I am seeing the left one fail indicating no seal. Maybe it is accumulating dirt over time?


Also, I can tell as soon as I put them in if I’m going to get a green indicator of a good seal. I always have NFC on. When I put them in, with NFC ON, the NFC is either working well or not. When working well, it always passes. If the NFC doesn’t seem to be working fully, I get a bad seal test. Maybe this is an indicator that the mic is working properly (and not clogged up)?


When I first bought them, went back an forth trying the different tips. The holder for the extra tips is paper. When I removed (I think the large ones), a thin later of paper from the top of holder came off and was stuck on that tip of the AirPods Pro so, of course, there was no sound from that ear and there is a safety issue with small paper discs in your ear!

I think there is something wrong with the electronics or software for this tip test. For reasons I won't go in to, I've had 3 different sets of airpods pro with the same trouble. Just like yours, except it's my right airpod. Great fit test right out of the box and for a day or two, then the right one consistently fails no matter what I do. 3 different sets can't be a coincidence, and I don't think my ear canal is changing each time.

I experienced the exact same thing. The ear tip test passed for me using the medium tips for a couple of days. Then the left started to fail the test and now both fail consistently (as do the small and large tips). I have no idea if it is degradation of the tips or something in the software/firmware of iPhone and AirPods Pro. The testing is very erratic even doing it multiple times in a row. These sound great and the failed test bothers me because it makes me think I can get better sound and noise cancellation but in reality there is nothing wrong. So providing a unreliable/erratic test suggests a problem with the hardware when there probably isn’t one at all!

I will return them back. They only gave us 3 sets. Usually everyone else provides 6 sets. I tried for hours and non of the tips worked. Apple say that it will not provide NC if the seal is no good.

That means we are not getting a full NC when the seal is not complete. I was not able to get a good fit after I tried every tip.


I am sure they are working now on Airpods Pro2 so I am glad I returned it.

A smart salesperson in Bellevue said that this test is for nothing! They should not even have this on the app since it will either work or fail each time. The only time your can get good seal if you put a pressure on earbuds. So I do not care anymore. I use Broski Leta ($100.00) light headsets not to listen screaming kids on the plane. I highly recommend it!

I do really like the AirPods Pro but there is definitely a design issue with them. I replaced them a few times due to rattling or buzzing, lack of bass and persistent failure of the fit test. The fit test is a cool idea but is frustrating because it starts to fail within a few weeks of starting to use a new AirPod pro (the right one fails first for me). I also often hear a buzzing or vibration when I talk on the phone. Maybe the active noise cancellation and particularly the active EQ might be the culprit causing problems? I totally agree with Changren that we shouldn’t need to suck them or use Blu-Tack to fix them periodically. I can’t image doing that is good for whatever delicate parts are inside the AirPods Pro. The easy pairing and automatic recognition of them on your other iCloud devices, compact size and overall ease of use and sound quality (when they are working) overrides the many quirks (for me). I guess the saving grace for these is the tight integration into Apple’s devices.

I am experiencing the same problem. First the left consistently failed, and then the right. I switched back and forth after I bought a set of four new tips and now they both always fail. Even with brand new tips. I tried both new pairs and the old pair and get the same result. I am not to worry though because it as much as I’ve read about it it sounds like a hardware/software issue. The sound, transparency, and noise cancellation still sound great.
