Apple's latest AirPods Pro 3 have introduced a groundbreaking feature that's catching the attention of fitness enthusiasts: an integrated heart rate sensor. Professional triathlete and renowned tech reviewer Ray Maker from DC Rainmaker recently put these earbuds through comprehensive testing, and the results have surprised even the most skeptical observers.
Revolutionary Infrared Technology Sets New Standard
The AirPods Pro 3 employ a sophisticated approach to heart rate monitoring that differs significantly from previous Apple attempts. Located on the sides of each earbud, small black areas conceal dual infrared sensors that pulse light at an impressive 250 times per second. This technology represents a notable departure from the green LED sensors used in the PowerBeats 2 Pro, which failed to deliver reliable results. The infrared sensors analyze blood flow patterns within the ear canal, measuring the subtle movements of blood to calculate heart rate with remarkable precision.
Technical Specifications
- Heart rate sensor: Dual infrared sensors pulsing at 250 times per second
- Water resistance: IP57 rating (1 meter depth for 30 minutes)
- Price: USD 249
- iOS requirement: iOS 26 for enhanced Fitness app features
Comprehensive Testing Reveals Impressive Accuracy
Maker's testing methodology involved comparing the AirPods Pro 3 against the PowerBeats 2 Pro during both indoor and outdoor cycling sessions. While indoor cycling provided more controlled conditions for both devices, outdoor testing presented real-world challenges including elevation changes and environmental factors that typically compromise sensor accuracy. The AirPods Pro 3 demonstrated superior performance in these demanding conditions, maintaining consistent readings throughout most of the workout sessions.
Testing Comparison Results
| Feature | AirPods Pro 3 | PowerBeats 2 Pro |
|---|---|---|
| Indoor cycling accuracy | Excellent | Good |
| Outdoor cycling accuracy | Very Good | Poor |
| Sensor technology | Infrared (250Hz) | Green LED |
| Peak interval tracking | Minor struggles | Significant issues |
Minor Limitations Don't Diminish Overall Performance
During peak interval training, the AirPods Pro 3 occasionally struggled to capture heart rate data at the highest intensity moments. However, this minor limitation didn't significantly impact the overall accuracy of the workout data. Maker expressed genuine surprise at the earbuds' performance, stating he had fully expected the AirPods Pro 3 to fail based on Apple's previous attempts with optical heart rate monitoring in the PowerBeats line.
Enhanced Fitness Integration Expands Functionality
The heart rate monitoring capability integrates seamlessly with Apple's enhanced Fitness app, which received significant updates in September. Users running iOS 26 can access the new Workout tab, which offers various exercise tracking options with customizable features. These include automatic music playback during workouts, motivational coaching through the Workout Buddy feature, and flexible workout parameters for time or calorie-based goals. Post-workout data appears both in the Fitness app and on the iPhone's Lock screen through Live Activity notifications.
Fitness App Features

- Workout Buddy motivational coaching
- Customizable workout parameters (time/calories)
- Post-workout data display on Lock screen
- Integration with Live Activity notifications
Durability Meets Performance in Real-World Conditions
The AirPods Pro 3 carry an IP57 rating, enabling them to withstand water immersion up to one meter deep for 30 minutes. Maker tested this durability claim by wearing the earbuds during swimming sessions, and they survived the aquatic challenge without compromising functionality. This water resistance, combined with the accurate heart rate monitoring, positions the AirPods Pro 3 as a versatile fitness companion for various athletic activities.
Market Impact and Future Implications
Maker's conclusion that Apple has achieved something really nobody else has in producing reliable heart rate sensing earbuds suggests significant implications for the wearable fitness market. At USD 249, the AirPods Pro 3 offer a compelling combination of premium audio quality, advanced noise cancellation, and now proven fitness tracking capabilities. This convergence of entertainment and health monitoring technology represents a notable step forward in making comprehensive fitness tracking more accessible and convenient for everyday users.
