One 4 pin plug as shown. Clean new old stock Although these are non locking, you can use to connect many old microphones Shure, EV etc as long as cord will not be pulled on, these work fine, or add a zip tie etc to hold cord from being pulled. The spacing of the pins is such that it can only plug in one way and is standard for many old 4 pin EV and Shure mics. (or see our other listings for 3 pin versions) The inner phenolic body can also be taken out and used to repair microphones or replace the plug inside your existing amphenol 91-mc4m locking connectors. (or see our other listings for those) Most are still in GC electronics blister display packs that hang tags may have sign of aging but plug is perfect
