For those seeking a basic summary: This microphone does its job, does it well, and holds the same quality of sound that the factory-supplied microphone does. Soles are much thinner than my last years pair It even comes fully charged! I bought this used because it said amazon refurbished. Will probably buy more. Wish it was available in a smaller size. Looks aside, these shoes are comfortable enough if you size up (they ran a whole size large for me), but since theyre made of a solid material without ventilation holes, the shoes heat up quickly! The service was excellent and super quick! I have included a photo of this. It doesnt get five stars because of the balky controls.
