Apple’s AirPods Pro 3 are doing more than just delivering great sound. They now monitor your heart rate with surprising accuracy. This feature puts earbuds in direct competition with smartwatches for fitness tracking.

The heart rate sensor inside these earbuds uses photoplethysmography, or PPG. It shines infrared light inside your ear canal to detect blood flow changes. The sensor samples data 256 times per second, which helps it stay accurate even during movement.

Tests show the AirPods Pro 3’s heart rate sensor comes very close to the Apple Watch Series 11 in accuracy. One lab found an average error of just 1.67% compared to a medical-grade chest strap, while the Apple Watch was even better at 0.98%. This means the earbuds offer reliable heart monitoring for most users.

What makes ear-based sensors special? The ear canal offers a more stable environment than the wrist. It blocks out ambient light and reduces motion noise that often disrupt wrist sensors. This stability helps AirPods deliver consistent heart rate readings during steady activities like running or cycling.

Why Earbuds Are a Game-Changer for Heart Monitoring

Many people dislike wearing smartwatches all day. Some find them bulky or forget to charge them. AirPods solve this by being earbuds you likely wear anyway. You put them in for calls, music, or workouts, and they quietly track your heart rate in the background.

This passive monitoring means you collect health data without extra effort. Plus, AirPods Pro 3 cost less than an Apple Watch—about $250 compared to $400 for the latest watch. For those not ready to invest in a smartwatch, or who want a simpler option, these earbuds offer a compelling alternative.

Apple’s Health app integrates the heart rate data smoothly. It shows historical trends and sends alerts for unusual heart rates. The earbuds can even notify users about high or irregular heart rates, although they do not detect arrhythmias or perform ECGs like the Apple Watch does.

How AirPods Pro 3 Compare to Other Fitness Trackers

Compared to other earbuds, the AirPods Pro 3 lead in heart rate accuracy. Samsung’s Galaxy Buds 3 Pro use a single wavelength sensor and show bigger errors during exercise. In tests, Galaxy Buds had an average error over 6 BPM during running, while AirPods stayed near 2 BPM.

Wrist-based fitness trackers still dominate for detailed health monitoring. The Apple Watch Series 10 remains the best for cardiac health, with FDA-cleared ECG and atrial fibrillation detection. Garmin and Polar devices offer strong workout-grade heart rate data but require wearing a watch all day.

There are also finger-based options like the Oura Ring, which excels in resting heart rate and heart rate variability tracking. Still, it can’t provide real-time workout heart rate feedback like AirPods or smartwatches.

Overall, the AirPods Pro 3 fill a unique spot. They combine excellent audio quality with accurate heart rate tracking in a device worn in the ear instead of the wrist.

Real-Time Heart Rate in Your Favorite Fitness Apps

Strava, a popular fitness app, now supports live heart rate data from AirPods Pro 3. This means runners and cyclists can track their heart rate without a chest strap or smartwatch. The earbuds send data straight to the app during workouts, offering a seamless experience.

Strava has also expanded to track more activities, including basketball, dance, and volleyball. This shows how fitness tracking is evolving beyond just running and cycling to capture many forms of movement.

This real-time integration makes AirPods Pro 3 not just a casual heart rate monitor but a practical tool for athletes and fitness enthusiasts.

What’s Next for Heart Rate Monitoring in Earbuds?

Apple’s work with ear-based sensors is just beginning. The S10 chip inside the AirPods Pro 3 has extra processing power for future features. A recent firmware update enabled atrial fibrillation detection, showing Apple can add health tools via software upgrades.

Researchers are exploring even more advanced measurements from the ear, like continuous blood pressure or glucose monitoring. These would be breakthroughs for millions managing chronic conditions.

For now, AirPods Pro 3 offer a convenient, accurate way to track heart rate without extra gadgets. They might not replace smartwatches for medical-grade monitoring. But for everyday fitness and health awareness, earbuds have become a serious contender.

If you already use AirPods, your next workout might be smarter than you think. Just pop them in, and your heart rate starts tracking automatically.
