I have tested this in the last few days of ownership. Since he had CVC 8 I figured the calls would be great. Unfortunately, according to the people on the other end, the calls aren't that good. Even at the slightest moment on my end, the other caller says I sound far away. I tested on Samsung A70. The sound quality is really good when listening to music and audio books, and it also sounds great when making calls on the other end. I just want the mic to work well for calls. So I'm going to use it for listening and random quick calls. For the price, you really can't go wrong listening to music and videos. The device is soft and flexible, so wearing it for more than an hour will not cause any discomfort. The device can be worn on both ears and the MFB and + and - buttons are responsive.
