XLR to 3.5mm Mic Cable, Unbalanced XLR Female to 1/8" for DSLR, Camcorder, PC...

(This 3.5mm to XLR cable is designed to feed the mono mic signal to input channels on the camcorder/computer. If you only have one, it's a combo and this plug probably won't work at all.). XLR to 3.5mm compatible with handheld, lavalier, shotgun and condenser Microphones.
