I connected it and disconnected it several times to hear the difference. Working from home, I found I needed an alternative to using my laptops built-in speakers and microphone for business meetings. Its not too big of a deal, as I could mute using software but Id have really appreciated having a feature like that. I?m an 16/18 44DD and xxl was perfect. I got it in XL. I have a wide foot and a foot that often swells so wearing my regular flip flops became a problem. In that I have had Crocs that I wore every day for many years, I may never wear these out. The bottoms seem to have some sort of fabric layer that apparently makes it super simple to slide, which is terrible! Kinda hard soles. I was told that there are very little outlets in our room and I should purchase this.
