• Experience of taking the subway: The subway is a common commuter vehicle for our daily commuters, and its noise mainly comes from wind noise and low-frequency noise of subway operation. In the actual experience, the Xiaomi Buds 4 Pro can filter out most of the low-frequency noise well by turning on the noise cancellation at the maximum gear. And when the volume is turned up to 50%, basically no noise can be heard. Of course, the sound of the station announcement is completely audible through my actual experience, so I don’t have to worry about missing the station.
