I am a training coordinator for my company, I am the one that listens to all the calls for training purposes, but I also take overflow calls when were busy. The awareness mode sounds like im not wearing headphones at all, Really clear and makes it easy to understand when people are talking to me. I have a broken left foot that has caused the shape of my foot to change due to the break. He wore His dad?s crocs around the house. I feel theyre a good value for the money. I may try again when I order other things at the same time. Used X-Treme Tape TPE-X36ZLB Silicone Rubber Self Fusing Tape, 1" x 36, Triangular, Black (amazon), works very well. Now, theyre extremely comfortable. These are fantastic and the sound quality is amazing the bass is good and when I have them in you could scream at me and I will not here you. I hope all the vendors do this.
