SONY ECM-CS3 condenser microphone. It connects via a 3.5mm jack and offers clear sound quality. It was stored after being used for a series of meetings (about 10 times total). The SONY logo is partially peeled off, and the plating is partially worn off near the bottom of the "Y" and on the edge of the microphone on the "S" side. For the listing, I have connected it to a SONY stereo recorder ICD-UX560F and recorded a sample, which you can check at the following link: https://drive.google.com/file/d/1rdcG9QkJccg1GYr5TLCWDRT_p-w4Hh46/view?usp=drive_link - Brand: SONY - Model Name: ECM-CS3 - Connection Type: 3.5mm jack - Instruction Manual: Included Thank you for looking.
