Sennheiser's NoiseGard

Sennheiser's NoiseGard  做得好唔好?   如果有人係旁邊同我講野, 我聽唔聽到?

有個網站話:"The noise-cancelling circuitry may reduce audio quality and add high-frequency hiss, though reducing the noise may result in higher perceived audio quality.",  

noisegard 是不是也一樣?

主動抗躁本身係抵消持續性低頻

旁邊同你講野, 你聽唔聽到係睇被動隔音有幾多 同埋你開得幾大聲

正常情況你聽緊歌唔會聽得到人講乜
