Snap in the right fit
First look at the silicone ear tips included with your AirPods Pro. The medium-sized ones – suitable for the average user – are already attached. Two other size, small and large, are also included in the packaging.
If you haven’t already tried them out, give the medium-sized ones a try and see if they rest comfortably in your ears. Give your head a good shake and move around to make sure they’re seated securely. If you feel them moving around, try adjusting them a bit to see if you can find a more comfortable position.
If they simply don’t feel right, switch to the larger or smaller tips until you find ones that work. To remove them, gently squeeze and pull the silicone tip away from the rest of the AirPod. You’ll feel it detach, then you can attach the size you want. You’ll feel a gentle click or snap when the silicone tip is correctly attached to the AirPods.
Bear in mind that it’s entirely possible you may find that one size works better in one ear than the other. You might find that your right ear is more comfortable with the medium silicone ear tip, for example, while your left ear works better with the large. Find a combination that’s right for you.
How to run the Ear Tip Fit Test
If you’re not sure if you have the best ear tips for your ears, or if you want to make sure, Apple’s made it really easy to find out for sure with the Ear Tip Fit Test, a built-in function of the AirPods Pro.
First, attach a set of silicone tips that you think fit you best. Then on your iPhone:
1) Tap Settings.
2) Tap Bluetooth.
3) Tap the Info button next to your AirPods, in the list of connected Bluetooth devices.
4) Tap Ear Tip Fit Test.
5) Tap Continue.
6) Tap the Play button.
If everything goes well, you should get green Good Seal indicators from the test.
If not, the test may suggest adjusting or even trying a different ear tip. Give your AirPods Pro an adjustment, remove the silicone ear tips and try a different pair, and test again. Remember: don’t be afraid to mix and match different sizes, if you need custom sizes for each ear.
