The next generation of XLR connectors provides unequalled performance for the most demanding applications.
the most popular XLR connector on the market is the older X series of this same connector and it is the industry standard because it is durable, easy to soldier and repair, and it has the best strain relief on the market. that was until they came out with these XX series. XX has a much larger and stronger strain relief allowing for longer lead wires and it wont allow the cable to turn like the older ones will so you wont have problems with long lead wires being wrapped around themselves and causing a short. plus they are black which is more discreet and they cost the same.
Very good design
I have dealt with MCM Electronics a number of times and have been more than satisfied.
