I only use it to listen to my own voice. Like I literally just used it yesterday because during one of my work meetings, there was an echo and I kept hearing my voice after everything that I said, and my voice sounded so god-awful that I needed to like practice talking into my phone
The one you hear when you speak is filtered through your skull that’s why it sounds so weird when played back i just got to know about it don't knowhow true it is but it is what it is.
