I want to buy when I need to ride. When I heard it, it was not just me.
It sounds like a ripple, but it is not inconvenient when riding.
It does not deviate much from other people's testimony. It can be used satisfactorily for the price. The sound seems to be due to the different degree of close contact depending on the face type. The unit is thick and not slim.
