I see YouTube videos a lot. But I see videos in 2x playback speed. I see videos in my pc most of the time. I used Samsung galaxy s10, OnePlus 7 but there is no change in sound quality while playing any video in speed. But in iPhone the sound quality get muted or harsh while playing those videos in iPhone. I tested this problem in iPhone 5s,6 and X. I want to know why this is happening ?
