They?re the correct size! The fuzzy on the end of the microphone is also of good quality. Great headphone, fits my ear very well and very comfortable. Im gonna get another pair before they stop making this design. I have mounted many things over the years. He is super happy with his compression shirt. This unit is a great addition to my classic car, in which the previous removed the cigarette lighter because a custom wiring job was performed. The slider is not as exacting as the Apple control. Just from general use the microphone starts to have problems within 4 or so months. I love that there is 8 Channels to choose for quality.
