AirPods Pro will feature three sets of tips, small, medium, and large
Apple hasn't offered its own set of in-ear earphones for a little while, so a lot of people are used to the company's "one size fits all" approach for the EarPods and, more recently, AirPods. But since AirPods Pro are in-ear by nature, a little more customization is welcome.
Apple's latest earphones will come with one set each of small, medium, and large ear tips. Using the right ear tips on the AirPods Pro is helpful not only for comfort but to aid in the noise cancellation process by providing the best possible seal between your ear canal and the noise of the world around you.
AirPods Pro will help you find the right ear tips for you
Just as the HomePod uses sound to analyze the surrounding room to adjust the sound for its environment, AirPods Pro will analyze your ear. Upon connection with your iPhone and insertion into your ears, the AirPods will initiate the Ear Tip Fit Test.
The test examines the quality of the seal using algorithms and the microphones on the AirPods. The sound level in your ear is measured and compared to what's coming from the speaker driver. You'll get a message telling you either that your fit and ear tips are good to go, or that they require some adjustment.
