I purchased two of these for connecting microphones to my audio recorder. My recorder has neutrik female XLR input docks. Never had any problems connecting any XLR other cable. These cables were just to tight to fit in, I had to push in hard to get them in... unhooking them out was much more of a problem. Not worth endangering the recorder inputs, but also not worth paying for the shipping return. Might as well keep them and hope they work with other cables and connectors.
