Hi, I notice that everytime after the music or whatever sound stops playing, there is a faint hissing or white noise sound. It last for about 20 seconds and then become quite. The sound is barely noticeable unless you put your ear against the speakers. It also happens when I am using my airpods on my mac so I belive it is software related. I've seached online and some people seem to experience the same problem. I was wondering if any of you experience it as well. Thank you.
