The AirPods Pro never slipped loose, and I didn’t yank them out of my ears when pinching the stems to change songs or turn on Transparency Mode. The new design, though, means more listeners should find a better fit. First- and second-generation AirPods had an open-ear design that allowed a lot of surrounding noise in, meaning you had to crank the volume in noisy situations-subway platforms, airplanes, etc. That, plus silicone tips that fit snugly in your ear canal, make the Pro a totally different experience. An Apple rep told me during the event on Monday that they scanned thousands of more ears, using heat mapping to find exactly where the buds should make contact with ears-and where they shouldn’t. Previously, the AirPod was a love it or hate it device-those who were in the latter camp often said the buds wouldn’t stay in their ears. Best of all, there was only one short stretch during my six-miler, along the Hudson River, where I heard any noise from the wind at all. And, while I won’t say Apple’s pass-through audio is anywhere close to having your ears completely uncovered, if I keep the volume reasonable, I can hear approaching cars, bike bells, and even voices of people I run past (but I couldn’t make out their words). As you can gather from my AfterShokz comment above, I like to know when a Lexus SUV is about to mow me down. But, on the AirPods Pro, I left Transparency Mode enabled more often than not during my run along the city’s sidewalks. We’ve seen this feature, by any name, implemented a number of times on earbuds in the past and it’s always sucked, simply because wind rushing over those microphones caused far too much whooshing static to be tolerable. When it’s enabled, the microphones mix ambient sound into the music you're listening to. Those same microphones that provide the noise cancellation also turn a cool trick to let you actually hear the outside world whenever you want-Apple calls the function Transparency Mode. In my first run, I found the buds were comfortable, they never slipped loose or needed adjustment, and the “thump” was all but nonexistent. This is a byproduct of a novel venting system that Apple claims equalizes pressure inside your ear for better comfort. With AirPods Pro, however, I found the audio to be cleaner at lower volumes, mostly because I wasn’t suffering that “thump” 180 times every minute. Plus, to drown out truly loud racket, you have to jack up the volume. I’ll admit, I hate that “thump.” And in addition to safety, it’s one of the biggest reasons that I reach for bone-conduction AfterShokz instead of standard ear canal-obstructing buds. That conventional method’s downfall for runners, of course, is the loud “thump” that rattles your eardrum with each foot strike. Such functionality is typically reserved for larger on- and over-ear headphones smaller buds usually just block out sound by sealing your ear canal entirely. The result is the original noise is muted, if heard at all. This effect is achieved by an acoustic technique called phase cancellation, where the speaker creates another sound wave of the identical frequency but 180 degrees out of phase with the original-its wave shape is the exact opposite of the sound you're eliminating. The biggest difference between the Pro and early models of AirPods is the Active Noise Cancellation feature, which uses a microphone in each bud to measure external noise, plus another to gauge the sounds that slip past the silicone ear tip, to cancel out anything that’s not coming from the speaker itself. And if my first day spent navigating New York City subways and running Jersey City streets is typical, they’ll be the only earbuds you need to cover all of your listening needs. Then again, AirPods Pro come with a premium price tag because they’re doing a lot more under the hood to ensure only your music makes it to your eardrum. Let’s get the big complaint out of the way up front: Some of you will balk at spending $250 on running headphones.
