Update (1/18/2020): Considering the number of poor reviews for this product, I thought I should stop by again to say this towel bar is still working VERY well for me. But When received, totally out of my expection. (Cue angels singing from above ??)Im a teacher, and almost 40, so Im done with sacrificing comfort. Barely any difference noted when turning noise cancellation on and off. Extremely comfortable and stylish. I have narrow feet so its not a matter of the flip flops being tight. Its like they tried to recreate it so it would fit in your ear and make sure no other sound got in but theyre really uncomfortable and I actually got a scab in my ear from wearing it too long. Sometimes I wish the head strap would be a bit stiffer. I m very very disappointed and regret why I bought this phone from the Bree Phony company ever. As someone who needs to attend calls quickly when not listening to music, this was a major blocker.
