I am the second owner of these CAD (Conneaut Audio Devices) Equitek E100 mics & have had them for about 5 years now. They show some discolouration of the grilles but work flawlessly. These are being offered as a matched pair with individual flight cases included as shown in the photo. Great large diaphragm condenser performance for stereo live recording applications as well as for individual use on vocals or instruments.
