So I figured Id give this a try. Anyone that claims these are just as good as the originals are lying. you hear the call really well, but sometimes especially if Im in a noisy environment the mic is having trouble picking up my words. Well made item. In the photos, you can compare the original single screw and washer and then the 20-screw upgrade. Super easy installation despite the instructions being written in Chinese. Wear them to death! 5, in Nikes I wear an 8, and these flip flops the 9 fits perfectly. So this year i decided for a new model andis even better then my expectations. So firstly in terms of the microphones, they are not good to be Frank.
