Called the ConvertCon (not to be confused with the "Conversion Convention '08"), the connector utilizes a sliding collar, allowing it to mate with either a female or male XLR.
Other features include an improved strain-relief collar and a durable zinc shell.
I wonder if it's truly cost effective for high-volume cable makers to change over, since barrels, while essential, are usually needed only once in a while. Personally, I think it's brilliant; when you're bagged up and run'n'gun, the last thing you want to do is add weight with a full "goody package" of adapters.
