I was watching a youtube video in cable transmission, particularly the basics of impedance matching and at time 6:06 in the video when the video says these kind of things affect the signal in a bad way I could not help wonder if what I did to some of the headphones (a section of the cable made back and forth and tied up) to reduce the cable length would in anyway affect anything at all?



The screen shot of the video - I have highlighted in blue oval what the video says is bad.
