I decorated them to suit my style. The cotton tips are very dense, but they really wick away moisture in my ears when I use them after showering. Easy to pair with my Android phone. I went to youtube instead, and learned that the mic has a sensitivity knob which is just below the volume knob. I?m giving it a 4/5 because one of the rubber pieces on the bottom came a little bit damaged but it wasn?t such a big deal. The part that connects to the mic is too wide to fit within the mount. At 20 Hz and at 20kHz there was no sign of saturation or added distortion. Very happy with the quality of the shoe and the comfort for wearing it in the kitchen (with no socks). I tried troubleshooting all aspects of the connection from the wiring to the mouse receiver, never giving a thought of the software because in 2019 I thought taking Plug n Play for granted was a thing. :-) I mostly listen to classical music, including a lot of pipe organ, and these do a great job.
