In Stock. The D-880M is the first in a series of microphones from AKG that have removable modules that can change your mic from wired to wireless, just by swapping out the "stock" module for a TM-40 wireless module. Plus, the D-880M is simply a great sounding, high output stage microphone that will get plenty loud without the fear of feedback. All together, this is a mic that can't be beat!
