Here's a Shure SM50 Dynamic Microphone from the 1970's (2 Available at $150 Each)! These omni-directional dynamics were for field use and built to withstand outgoing broadcasting uses. Shure didn't make many of this model, so they are relatively rare and unheard of. If you've been looking for a unique omni microphone for all studio uses, one of these is the microphone for you. Both of these are in perfect working condition with new foam and some cosmetic wear to their bodies. Grab one of these lesser known SM50's from Shure!
