Realme Buds Air Pro NOISE REDUCTION

When in noise reduction mode, the realme Buds Air Pro collects external noise through a built-in microphone, which is then neutralized by generating an equivalent reverse sound wave.
When in transparency mode, the realme Buds Air Pro collects external sounds, improving your ability to perceive and communicate with your surroundings without taking the earbuds off.
The noise reduction function can reduce, but not eliminate, low-frequency noise.
If you feel that the noise reduction function isn’t working for you, select some appropriate earplugs to improve your experience.
