Each earphone comes with three different sizes of earplugs to fit the ear shape, which is comfortable to wear and can achieve high density, which is also the key to active noise reduction or more immersion.
Because of the in-ear design, the earphone fits the ear hole more closely. In order to further improve the comfort, AirPods Pro adopts a new ventilation system to balance the pressure and minimize the discomfort common in other in-ear earphone designs. Moreover, this headset is also sweat-proof and waterproof (like the previous two generations, Apple has not specified the waterproof level).

Product performance:
On the headset chip, this product uses Apple H 1, which is the same as the second generation AirPods. This time, H 1 is packaged with other components by Apple System-in-Package (SiP) technology, and the high dynamic range power amplifier efficiency makes the sound more pure.
Apple allows introverted microphones to participate in the listening process. In addition to noise reduction, it also participates in sound optimization, and can adjust the middle and low frequency parts. The H 1 chip has 10 audio cores, and the audio processing delay is extremely low, which can reduce noise in real time and ensure sound quality. Compared with the previous generation, it is more energy-saving, and of course it also supports functions such as "Hey Siri" voice wake-up.
Its active noise reduction function is to use two microphones combined with Apple's algorithm, which is constantly adjusted according to the personal ear shape and the wearing fit of headphones. Its active noise reduction principle is the same as other brands in the industry, and it also produces reverse sound waves to offset noise, but the specific methods are not the same. It has two microphones to detect the noise inside and outside the ears.
According to Apple's instructions, the first microphone is extroverted and will detect external sound waves and analyze environmental noise. Subsequently, before these background noises enter the user's ears, AirPods Pro will cancel them with equivalent anti-noise waves. The second microphone is designed inward, which will detect the noise in the ear, and then AirPods Pro will also cancel the detected excess noise. The noise reduction function continuously adjusts the sound signal at a frequency of 200 times per second.
