His look exactly like this! This may be the model the reviews are talking about :( I used them for my meetings and everyone could hear me perfectly fine and I could hear them. I will note it's a tad softer than regular earbuds since it's bone conducting vs direct ear canal sound but I just turned the volume up more since it's not harming your eardrum as much and it worked great!
I will add - for anyone with long hair or any irritation with things sitting at or on the base of your head; the back part of the headset sits there so if that's uncomfortable for you then these won't work :(
