How is the noise cancellation performance of the Redmi Buds 6?

The earbuds feature an in-ear design, and in normal use, the Active Noise Cancellation (ANC) depth reaches up to 49dB. The effectiveness of in-ear noise cancellation will vary depending on the shape and size of the wearer's ear canal, how tightly the earbuds are worn, and the angle of wear.
Note:
1. For safety reasons, it is advised not to wear the earbuds while biking or crossing the street, as you need to be aware of your surroundings;
2. The earbuds support three levels of noise cancellation (light, balanced, and deep), which you can switch manually according to your needs.
