Key Takeaways
1. The Apple AirPods Pro 3 features a PPG heart rate sensor using infrared light, differing from the optical sensor in Powerbeats Pro 2.
2. The new PPG sensor is smaller and more accurate than the previous Powerbeats model.
3. AirPods Pro 3 provides similar heart rate readings to Garmin’s high-end smartwatch during intense workouts.
4. The heart rate sensor allows users to monitor their heart rates without needing additional devices like smartwatches or chest straps.
5. Apple has made significant advancements in heart rate sensor technology in a short time, improving user experience for fitness tracking.
Just like the previous model, the Apple Powerbeats Pro 2, the Apple AirPods Pro 3 (starting at $249 on Amazon) also includes a heart rate sensor. However, it’s worth noting that the sensors used in these two headphone models are different. While the Beats version employs an optical heart rate sensor with a green LED and captures data over 100 times per second, the AirPods Pro 3 are equipped with a PPG sensor that operates using invisible infrared light at a frequency of 256Hz.
Improved Accuracy
The new PPG sensor from Apple is their smallest yet and is considerably more precise than the optical sensor found in the Powerbeats Pro 2, according to an analysis by DC Rainmaker. Although the AirPods Pro 3 may not gather data as frequently as the Garmin Fenix 8 Pro under certain circumstances, the accuracy of the data collected is remarkable. During intensive interval training sessions, Apple’s wireless earbuds delivered nearly identical readings to those of Garmin’s top-tier smartwatch, as reported in DC Rainmaker’s reviews.
Convenience for Users
As a result, the heart rate sensor is reliable enough to monitor heart rates during exercise, meaning users don’t have to rely on a smartwatch, a separate chest strap, or a smart ring to track workout intensity. Given that the Powerbeats Pro 2 struggled with accuracy in this area, it is encouraging to see Apple make such significant advancements in sensor technology in just a few months.
