I didn’t have time to try it properly, because I ran into what I was afraid of - incomplete compatibility with the phone. Its pros: - Comfortable. - The sound is normal. - Convenient dongle to use with your phone. - Standing near the 10-lane highway, I spoke calmly, I was heard normally. Some cons: - With my Huawei P10, they do not work in talk mode over cellular (we are talking about wireless mode). Whatsapp works. This is a feature of the phone (perhaps many phones with a jack). So I had to give up. - The microphone is detachable, not hidden inside or otherwise.
