Two stars because the ear piece and microphone can work. But if I give it a twist, to reposition the microphone, there is a fifty-fifty chance that the microphone cuts out. Fortunately, with a some more twisting, I can get the microphone to work again. That was my experience.Would recommend searching for an adapter that would offer you a standard 2.5mm jack instead. I found one at [...], but I have not yet tried it.
