This is a new-open box unused Sennheiser ME64. It's a really useful little short short cardioid mic, but does require the K6 power module to work. Please note that bit, the K6 is not included here. Unlike the "open-box" lenses 105mm and 60mm, bought as such from BH, this was bought absolutely new (from Adorama) and is listed as "open-box" because as you can see, I did open it.
