This is a Sennheiser MKH 416 super-cardioid microphone. I've used it for about 4 years, and I've confirmed that it works properly. As shown in the fourth photo, the power supply inside is loose and tends to come off, but I've been using it secured with tape. There are no issues in use. The case and a foam windscreen are also included. This is a more professional model than the MKE 600. Please comment if you have any questions.
