Yo NS, I'm selling my Olympus ME51S stereo microphone along with a mini-usb to female 3.5mm headphone jack cord. This is a GoPro brand cord and works great with this mic and a GoPro. Ive used the mic once and the sound is great, I just bought another mic and never used this one. Looking for $40 shipped with the mic, GoPro cord, and lav clamp. pics below.
PM if interested or have questions
