The AirPods Pro 3 are a big upgrade over the AirPods Pro 2. Even though Apple has continuously added new features to those earbuds over the last three years, it hasn’t changed the design or shape of the earbuds since the first model arrived in 2019. With the AirPods Pro 3, you might not notice those tweaks until you remove the new ear tips, and the most impactful upgrades are all on the inside. After my brief hands-on immediately following the iPhone 17 launch yesterday, I’ve since spent more time test driving all of the new features on the AirPods Pro 3 — from the improved active noise cancellation (ANC) to Live Translation and heart-rate monitoring. Stronger ANC through tech and ear tips Apple says the ANC on the AirPods Pro 3 blocks twice as much noise as the AirPods Pro 2 and four times as much as the original AirPods Pro. A big part of this is due to the ultra-low noise microphones and computational audio on the earbuds, but the new foam-infused ear tips are also playing a vital role. The latest ear tips are still silicone on the outside like the Pro 2’s, but they’re now injected with foam. This provides much better passive noise isolation to block out distractions, helping with high-frequency sounds like human voices. In fact, there were several times this week where an Apple representative had to tap me on the shoulder because with the AirPods Pro 3 on, I couldn’t hear them speaking right next to me. No matter how they did it, the fact that Apple does a better job of silencing chatty co-workers on the AirPods Pro 3 is a welcome change. It’s impressive when you consider much of the competition struggles to reduce the volume of human voices on their earbuds and headphones.

During simulated air plane noise and recorded sounds of a bustling cafe, the earbuds did well to reduce the unwanted distraction of both. What’s more, the AirPods Pro 3 silenced the busy demo area outside of the keynote, providing a welcome respite for a few seconds during an otherwise stressful day. Live Translation finally arrives Sam Rutherford for Engadget After Apple chatted up Live Translation in iOS 26 at WWDC, I was disappointed that those initial plans didn’t include AirPods. I should’ve known the announcement for the earbuds would come with the next iteration of the AirPods Pro. Like Google’s Pixel Buds, Apple’s take on the feature relies on a connected iPhone to do all of the heavy lifting, powered by the Translate app. However, you don’t need a prolonged interaction with a phone to turn on Live Translation. You can press and hold on both AirPods, ask Siri or set the shortcut for the Action Button to the task. As a reminder, Live Translation will be available on AirPods Pro 3, AirPods Pro 2 and AirPods 4 with ANC, because they all carry the H2 chip. During a quick demo, Live Translation worked well, quickly converting the Spanish an Apple representative was speaking into English, which Siri then conveyed in the AirPods Pro 3. There’s a slight delay, which is expected, since the captured audio is processed on an iPhone and then translated in the second language. That might make for some awkward pauses, but I’ll have to wait for more real-world testing to know for sure. I did notice that text translations appeared in the app before they came through the earbuds, but again, that’s not really a surprise since the iPhone is the brains of the operation. Plus, you’ll want to use the phone as a horizontal display here, since the app provides a real-time transcription for the person you’re talking to. One aspect of Live Translation that may go unnoticed until you actually use it on the AirPods is the role ANC plays in the process. After you activate the translation feature, active noise cancellation kicks in to reduce the speaker’s voice so that you can clearly hear the translation from Siri in the earbuds. This happens automatically, and during my demo I never felt like I needed to manually adjust the volume so I could better hear the translated English over the speaker's Spanish. Heart-rate tracking, but only for workouts Billy Steele for Engadget Another big addition to the AirPods Pro 3 is heart-rate monitoring. Apple first debuted this capability on the Beats Powerbeats Pro 2 and is using a photoplethysmography (PPG) sensor to measure light absorption in blood flow. Heart rate stats are visible only in the Fitness app during workouts though, so if you’re looking to keep tabs in other apps or Widgets, you’re out of luck. But when it comes to activity tracking, the chorus of accelerometers, gyroscope, GPS and a new on-device AI model combine with the PPG sensor to monitor stats for 50 different workouts.

Sure enough, my live heart rate was displayed on the workout screen alongside distance covered, average pace, calories burned and elapsed time. Once I completed that strenuous session, I could see my average heart rate in the Workout Details summary, just above a graph of the info. Improved audio through more air flow Apple loves to discuss air flow when it comes to audio performance in AirPods and the company redesigned the venting system in the AirPods Pro 3 to improve sound quality. The company also turned the ear tip so it’s beaming audio more directly into the ear. Along with Adaptive EQ, this combination provides noticeably deeper bass and a wider soundstage for more immersive spatial listening. To move all of that air around, Apple’s acoustics team devised a new set of fine-tuned chambers to maximize the overall flow. And as a result, the vent system had to be larger, so now the one on top of the earbuds is nearly twice as large as the one on AirPods Pro 2. Then, to properly harness all of that available air space, Apple had to slightly redesign the driver/transducer to achieve the necessary frequencies. Adaptive EQ has also been expanded since the inward facing microphones on the AirPods Pro 3 have been moved so they’re not obstructed by the sides of the ear canal as much. Sam Rutherford for Engadget Maggie Rogers’ “Alaska” was the test track of choice during my demo, a song I’m familiar with since I’ve listened to the album Heard It in a Past Life a ton. Beyond the enhancements to bass and the spatial effect, the thing that struck me about the audio upgrades was the level of detail the AirPods Pro 3 now provide. The separation of the bass drum and hand pan enhance the immersion, but there’s also the texture in the sound of both that is typically lost on most earbuds and headphones. I listened to the AirPods Pro 2 on the flight out here to refresh my memory and it was immediately apparent that Apple has made some big upgrades to sound quality on this new model.
