Apple’s next big software push lands Monday, September 15 — iOS 26 — and tucked inside the glossy list of iPhone upgrades is something a little quieter but genuinely useful for people who sweat, run, bike or just like checking their numbers on the go: the Powerbeats Pro 2 are getting a suite of heart-rate and fitness features that make them behave far more like Apple’s newly announced AirPods Pro 3.

This isn’t a firmware tweak that only changes a decimal or two. With iOS 26, Beats and Apple are expanding how those heart-rate sensors in the earbuds talk to the iPhone and Apple’s fitness services — real-time metrics inside the Apple Fitness app, compatibility with Apple Fitness+, faster readings, step counting, fit suggestions and even single-earbud monitoring. If you bought Powerbeats Pro 2 for workouts earlier this year, the update actually unlocks much of the functionality people assumed would be there from day one.

Beats launched the Powerbeats Pro 2 in February 2025 as its first earbuds with dedicated heart-rate monitoring. From the start, they pitched the buds as workout gear first: secure earhooks, long battery life, IPX4 sweat resistance and sensors that could read pulse while you trained. But at launch, the heart-rate data mostly flowed to partner apps (Nike Run Club was an early example), and the earbuds didn’t fully integrate with Apple’s own Fitness ecosystem.

That split left a gap: you’d get heart-rate numbers in a running app, but you couldn’t, for instance, use Powerbeats Pro 2 to show live heart-rate and calories on the Apple Fitness app or in Fitness+ classes the same way an Apple Watch can — until now.

Here are the practical things you’ll notice after updating to iOS 26:

• Real-time heart rate in Apple Fitness across 50 workout types. Powerbeats Pro 2 will show live heart rate in the Apple Fitness app during many more activities than were supported at launch.
• Apple Fitness+ integration. If you use Fitness+, your iPhone can now show Powerbeats-sourced metrics like heart rate, calories burned and the Burn Bar — without an Apple Watch strapped to your wrist.
• Faster readings via a new algorithm. Beats says a new measurement algorithm in iOS 26 improves the speed and responsiveness of heart-rate readings (Beats also plans the update for Android users, where supported).
• Step counting. The buds will be able to count steps even if you don’t have your iPhone or Watch on you.
• Fit-improvement notifications. Expect in-ear notifications suggesting how to adjust the fit for more accurate readings — a tacit admission that fit still matters a lot for ear-based PPG sensors.
• Single-earbud monitoring. You’ll be able to get heart-rate data while wearing just one Powerbeats Pro 2 bud, a convenience for people who want situational awareness or long battery stretches.

Those features collectively narrow the experience gap between the Powerbeats Pro 2 and Apple’s new AirPods Pro 3 — which Apple has marketed with its own in-ear heart-rate approach and tight Fitness+ integration.

Earbuds measure heart rate differently from a wristwatch. Most modern earbuds (and the AirPods Pro 3 documentation) use a photoplethysmography (PPG) approach: an infrared LED pulses light into the skin and sensors measure tiny changes in light absorption as blood pulses through the tissue. Apple’s documentation for the new AirPods Pro 3 goes into those sensor details (pulse frequency, filtering, etc.), and Beats has been clear that a correct fit and contact are essential for accurate readings. The iOS 26 algorithm improvements are meant to make that PPG data cleaner and faster to display.

A practical implication: a better algorithm helps, but it can’t fully undo bad fit, excessive sweat, or motion artifacts — which is why Beats’ fit suggestions matter. Reviewers and lab testers have repeatedly found that earbuds can be accurate enough for workouts and trend tracking, but they’re not yet medical-grade ECG replacements.

If you’re a casual runner or a Fitness+ subscriber who doesn’t wear an Apple Watch, this is one of those rare software updates that materially improves day-to-day usefulness. You’ll get live metrics on your iPhone during workouts, calorie estimates, and the Burn Bar — all tools Apple says help you stay engaged with a workout. For athletes who already use a chest strap or a dedicated ECG-capable device, earbuds are still best treated as a complementary metric rather than the single source of truth.

If you bought Powerbeats Pro 2 and found the heart-rate features inconsistent, expect meaningful improvement. If you’re shopping for earbuds primarily for health tracking, the odds just shifted a little in favor of Beats — mainly because Apple keeps tying more fitness features into the core iPhone experience.

Privacy, battery and accuracy notes

• Privacy: Apple and Beats route fitness metrics through Health and Fitness frameworks, which remain subject to Apple’s privacy controls; you’ll see permissions prompts when pairing or enabling these features. Apple’s documentation highlights on-device processing and Health app controls, but always double-check what you share with third-party apps.
• Battery: Powerbeats Pro 2 already promised long runtimes (case + buds totaling dozens of hours). Expect a small incremental battery cost when sensors are active during workouts, but Beats has designed the H2-powered system to keep the tradeoff reasonable.
• Accuracy: Ear PPG is improving fast, but if you need clinical-grade readings (arrhythmia detection, BP estimates, etc.), stick with medically certified devices and consult a clinician. Earbuds are great for trends and in-workout motivation, less so as diagnostic tools.

Why Apple is pushing this now

It’s part product convergence and part ecosystem play. Apple has been steadily moving health capabilities out of the Apple Watch silo: adding sensors to other wearables (like AirPods) and letting iPhones act as the display hub widens the audience for Fitness+ and strengthens the overall ecosystem. Making the Powerbeats Pro 2 behave more like AirPods Pro 3 is also tidy: users shouldn’t have wildly different experiences across Apple-owned audio brands. And from a competitive angle, it keeps Apple/Beats competitive with smart fitness earbuds from many rivals.

On September 15, when iOS 26 ships, Powerbeats Pro 2 owners should install the update and check the Beats settings and the Apple Fitness integration. The change transforms a previously limited heart-rate feature into something much more useful for real workouts and Fitness+ sessions. It’s not a replacement for a watch or chest strap in terms of medical accuracy — but for daily training, trends and motivation, it’s a big leap forward.
