AirPods Pro 3 Unveiled: Apple’s New Earbuds Boast Heart Rate Tracking, Live Translation & Best-Ever Noise Canceling

Key Facts

Major Upgrade After 3 Years: Apple has introduced AirPods Pro 3 at its September 9, 2025 event – the first major refresh of the Pro earbuds in three years ^[1]. The new model comes packed with innovative features aimed at vastly improving audio quality and user experience.
Best-Ever Noise Cancellation: Apple claims the AirPods Pro 3 deliver “the world’s best ANC of any in-ear wireless headphones,” offering up to 2× better noise cancelation than AirPods Pro 2 and 4× better than the original Pro model ^[2] ^[3]. New foam-infused ear tips and advanced microphones help achieve this unprecedented level of silence ^[4].
Built-In Heart Rate Monitoring: For the first time, AirPods include health sensors – each earbud has a tiny custom PPG heart-rate sensor that shines infrared light 256 times per second to measure the wearer’s pulse ^[5]. This allows users to track heart rate and calories during workouts using just AirPods Pro 3 and an iPhone (no Apple Watch needed) ^[6].
Real-Time Language Translation: A new Live Translation feature lets AirPods Pro 3 act as a personal translator. The earbuds can automatically translate foreign speech in near real time and play it back in your preferred language ^[7]. If both people in a conversation wear AirPods Pro 3, their spoken words are translated almost instantly for one another ^[8], making cross-language chats much easier.
Refined Design & Fit: Apple analyzed over 10,000 ear scans to redesign the AirPods Pro for better comfort and stability ^[9]. The AirPods Pro 3 buds are slightly smaller than before and now come with five sizes of ear tips (including a new extra-extra small size) using foam-infused material for a more secure seal ^[10]. They’re also rated IP57 for sweat and water resistance, making them more durable for workouts ^[11] ^[12].
Longer Battery Life: Efficiency improvements give AirPods Pro 3 about 8 hours of listening time per charge with ANC on – a one-third increase over the previous model ^[13] ^[14]. In Transparency (passthrough) mode, they can last up to 10 hours on a charge, which is roughly a 67% jump from the prior generation ^[15].
Price & Availability: Despite the upgrades, pricing remains unchanged – AirPods Pro 3 cost $249, the same as their predecessors ^[16]. Pre-orders begin today (Sept 9, 2025), and they will ship to customers and hit stores on September 19, 2025 ^[17].

Big Leap in Noise Cancellation and Sound Quality

Apple has significantly boosted the Active Noise Cancellation in AirPods Pro 3. Thanks to a new multi-port acoustic architecture and improved computational audio, these earbuds can filter out twice as much noise as the previous AirPods Pro 2, and four times more than the original 2019 AirPods Pro ^[18]. In practical terms, this means a far quieter listening experience in loud environments – Apple even touts it as “the world’s best ANC of any in-ear wireless headphones” ^[19]. The superior noise reduction is achieved through ultra-low noise microphones and new foam ear tips that passively block sound, combined with advanced algorithms ^[20].

Better noise cancelation goes hand-in-hand with improved sound. AirPods Pro 3 use next-generation Adaptive EQ to widen the soundstage and enhance audio clarity. The new acoustic design delivers richer bass and more vivid vocals, so users can hear every detail in music or podcasts ^[21]. Even Transparency mode (which lets outside sounds in) is more natural now – voices (including your own) sound less artificial when you’re conversing without removing the earbuds ^[22]. Notably, despite the stronger ANC and audio processing, battery life has improved: listeners get up to 8 hours with ANC on (versus ~6 hours before) ^[23], meaning you can enjoy the enhanced quiet and quality longer without recharging.

Apple’s hardware engineering lead John Ternus underscores how big an upgrade this is. “With AirPods Pro 3, the most popular headphones take a massive leap forward, providing fantastic sound quality and the world’s best ANC of any in-ear wireless headphones,” Ternus said ^[24]. He noted that the combination of improved fit, better noise cancellation, and new smart features takes personal audio “to the next level” ^[25].

Fitness Features: Heart-Rate Tracking in Your Ears

One of the headline additions to AirPods Pro 3 is the built-in heart rate monitor – a first for Apple’s earbuds. Each AirPod contains Apple’s smallest custom photoplethysmography (PPG) sensor ever, which shines invisible infrared light into the wearer’s skin to detect heart rate via blood flow changes ^[26]. Impressively, it pulses light 256 times per second to get accurate readings ^[27]. During workouts, these sensors pair with the AirPods’ motion sensors (accelerometer, gyroscope) plus the iPhone’s GPS and on-device AI to track your exercise metrics ^[28] ^[29].

In practice, AirPods Pro 3 owners can go for a run or hit the gym without wearing an Apple Watch, and still record fitness data. Using just the earbuds and an iPhone, you can monitor heart rate, calories burned, distance, and more for over 50 types of workouts ^[30] ^[31]. The new AirPods even integrate with Apple’s Fitness app: a feature called Workout Buddy provides real-time, personalized coaching feedback based on your heart rate and exercise history ^[32]. For example, the app might give motivational prompts or let you know when you’re nearing a goal, leveraging the live data from your AirPods. Apple says users can still “close their Move ring” (the activity goal from Apple Watch) using AirPods Pro 3, indicating the earbuds are fully capable of contributing to your daily fitness rings and awards ^[33].

This convergence of audio and health tech is a notable step. Industry observers say Apple is effectively turning its popular earbuds into fitness wearables. The inclusion of heart-rate sensing “matches what we saw get added to Beats,” noted tech reviewer Marques Brownlee, referring to similar health features in Apple’s Beats subsidiary products ^[34]. It’s a move that could attract fitness enthusiasts who might not own an Apple Watch but want basic workout tracking. And for existing Apple Watch users, the extra heart-rate data from ear-level might enhance accuracy or provide new insights (e.g. monitoring intensity during exercises where wrist-based readings falter).

Live Translation: Your Personal Babel Fish

Another futuristic feature debuting in AirPods Pro 3 is Live Translation, which essentially turns the earbuds into real-time translators. Powered by on-device Apple Intelligence and computational audio, Live Translation can handle face-to-face conversations across different languages nearly instantly ^[35] ^[36]. When activated, the AirPods listen to someone speaking a foreign language and then play back an audio translation into your ear in your preferred language. Simultaneously, Active Noise Cancellation will intelligently lower the volume of the person’s voice as you hear the translated version, helping you focus on the translation without losing awareness of the interaction ^[37] ^[38].

If both people in a conversation are wearing AirPods Pro 3, the system becomes a two-way translator – each person’s speech is translated into the other’s language in near real time ^[39]. And if only one party has the AirPods, you can use your iPhone’s screen to display translated text for the other person while you hear the audio in your ear ^[40]. Apple describes the experience as hands-free and natural: “When enabled, Live Translation helps users understand another language and communicate with others by speaking naturally with AirPods,” the company explains ^[41]. The feature is launching in beta form and initially supports English, French, German, Portuguese, and Spanish, with more languages (like Italian, Japanese, Korean, and Chinese) promised by end of year ^[42].

Tech experts are already buzzing about this capability. The real-time translation essentially gives users a “Babel fish” in their ear (a nod to the famous universal translator from The Hitchhiker’s Guide to the Galaxy), enabling seamless multilingual conversations. It’s a direct challenge to translation features in competing earbuds, such as Google’s Pixel Buds, and showcases Apple’s emphasis on AI-powered features in everyday devices ^[43]. While it’s not a replacement for learning languages, Live Translation could be a game-changer for travelers, international business meetings, or even casual cross-language friendships – all without having to pull out a phone or a translator gadget.

Refined Design for Comfort, Fit, and Durability

Though the AirPods Pro 3 may look similar to their predecessors at first glance, Apple has overhauled the design under the hood to improve fit and comfort. Engineers leveraged a dataset of over 10,000 3D ear scans (comprising more than 300 million data points) to tweak the shape and size of the earbuds ^[44]. As a result, each AirPod Pro 3 earbud is slightly smaller and shaped to sit more securely in a wider range of ear types ^[45]. The external angle of the ear tip has been adjusted – it’s now aligned centrally to the bud’s body – which increases stability during movement ^[46]. This means the AirPods are less likely to wiggle loose during activities like running or HIIT workouts.

Apple also introduced new ear tips made of a foam-infused material, which compress to fit the ear canal and expand to form a better seal. There are now five ear tip sizes included (XS, S, M, L, plus a new XXS option) ensuring even those with very small ears can get a comfortable fit ^[47] ^[48]. A tighter seal not only improves comfort and security, but also further enhances noise cancellation and bass response by blocking external noise leakage.

Durability has been stepped up as well. AirPods Pro 3 carry an IP57 rating, meaning they are dust-resistant, sweat-resistant and can even handle being submerged in 1 meter of water for up to 30 minutes ^[49] ^[50]. In practical terms, heavy rain or intense sweat should not pose any problem – great news for outdoor runners or those who use their AirPods during tough gym sessions. Apple clearly expects these to be your go-anywhere, do-anything earbuds; the improved water/sweat resistance and sturdier build aim to back that up.

Hearing Enhancements and Battery Life

Apple is continuing its push into hearing health features with the AirPods Pro 3. Last year, Apple introduced an end-to-end hearing assistance system via AirPods (including features like a Hearing Test and “Conversation Boost” to amplify voices for those with mild hearing loss). The new AirPods Pro 3 expand on this: their more powerful ANC and better acoustics can assist users in taking accurate at-home hearing tests and hearing conversations more clearly in noisy environments ^[51] ^[52]. In fact, when used in Transparency mode as a hearing assistance device, the AirPods Pro 3 can run for up to 10 hours – allowing extended use as over-the-counter style hearing aids for people who need that boost ^[53] ^[54]. Apple has even obtained certification in the EU and UK for certain hearing protection features, underscoring the earbuds’ dual purpose as both entertainment gadgets and health accessories ^[55].

Despite adding new sensors and features, AirPods Pro 3 manage to improve battery life across the board. We’ve noted the bump to ~8 hours with ANC on, but even the charging case likely holds more total charge (Apple hasn’t given an exact figure yet, but previous models provided around 30 hours with case recharges). The case still supports MagSafe, Qi wireless, and Lightning (or possibly USB-C this generation – Apple didn’t explicitly say, but the 2023 refresh of AirPods Pro 2 moved to USB-C). Regardless, day-to-day endurance will be better: Apple squeezed out more listening time so you’ll spend less time juicing up the case ^[56].

Additionally, iOS 26 (the upcoming software update) will introduce features that benefit AirPods users generally, such as using AirPods as a remote shutter for the iPhone camera and improved automatic switching between devices ^[57]. While not exclusive to AirPods Pro 3, these perks enhance the overall experience for those invested in Apple’s ecosystem and will work especially smoothly with the latest hardware.

Price, Availability and Outlook

Apple is keeping the price at $249 – the same launch price as the last generation ^[58] – which is notable given the breadth of upgrades in AirPods Pro 3. Pre-orders began immediately on announcement day, and units will start shipping on September 19, 2025 ^[59] (that’s also when they’ll be available in Apple Stores and other retailers). By holding prices steady, Apple seems to be aiming for wide adoption of these new features without pricing out existing AirPods Pro fans.

Early impressions of the AirPods Pro 3 are very positive. Many reviewers and tech experts see it as one of Apple’s most significant year-over-year improvements in the AirPods line. “AirPods Pro 3 [are] a no-brainer homerun,” veteran tech blogger M.G. Siegler commented on social media ^[60]. Others highlighted how these earbuds now blur the line between audio accessory and health gadget – offering high-end sound and noise cancelation on par with the best headphones, while also tracking fitness and translating speech in real time. It’s a unique combination only Apple currently offers in one package.

With these upgrades, Apple is fortifying its dominant position in the wireless earbud market. The company’s previous AirPods Pro were already hugely popular; by adding features like heart-rate tracking and Live Translation, Apple is differentiating itself further from competitors like Bose, Sony, and Samsung. If Apple’s ANC claims hold true, the AirPods Pro 3 could indeed set a new bar for noise cancelling performance, surpassing even the top models from rivals ^[61] ^[62]. And features such as translation and hearing assistance tap into Apple’s strengths in AI and health, expanding what people expect their earbuds to do.

In short, AirPods Pro 3 represent a comprehensive upgrade – better sound, smarter features, and more ways to use them – all while maintaining the same price point. As Apple’s press release put it, “AirPods Pro 3 take personal audio to the next level.” ^[63] For consumers, especially those already in the Apple ecosystem, these new earbuds look poised to deliver an unparalleled mix of entertainment, convenience, and even wellness benefits.
