BGR commended the Powerbeats Pro 2 for their exceptional audio quality, remarkable battery duration, and overall aesthetics, noting that the heart rate monitor may be overlooked by users who own an Apple Watch. When these earbuds were launched, Beats illustrated the functioning of these heart rate monitors.
Equipped with an LED sensor, photodiode, optical lens, and an accelerometer driven by a proprietary algorithm, the Powerbeats Pro 2 can capture information from both earbuds, yielding precise heart rate readings, with outputs generated every five seconds.
Although the measurement is solely effective during physical activities, it also implies the necessity for a compatible third-party application to exercise. Moreover, if a workout commences with the Apple Watch, the sensors of the Powerbeats Pro 2 become ineffective.
