AirPods Pro 3: Design change adds PPG sensor — some users report discomfort

Apple’s AirPods Pro (3rd generation) introduce a custom photoplethysmography (PPG) sensor that emits invisible infrared light pulsed at 256 times per second to measure blood flow and heart rate through the ear canal. This brings heart-rate and cardio-tracking features into the earbuds, working alongside motion sensors and on-device processing.

What the sensor does

• The PPG sensor pulses IR light 256×/s to detect blood volume changes in the ear canal.
• Provides live heart rate data during workouts and can contribute to calorie and activity tracking.

User feedback

Some users have reported discomfort or fit issues related to the new case/design and how the earbuds sit. Reports are mixed; Apple promotes an improved fit for active use, but individual ear shapes and sensitivity vary.

How to manage heart-rate monitoring

You can view and manage heart-rate monitoring for your AirPods Pro 3 via the iPhone Health/Fitness apps and AirPods settings. For detailed steps, see Apple’s support page: Monitor your heart rate with AirPods Pro (Apple Support).
