   wherein the left ear cup connector comprises: 
 a post disposed on the backside portion of the left ear cup and extending outwardly therefrom; and  
 an enlarged circular head disposed on a distal end of the post; and  
   wherein the second end mount connector comprises; 
 a housing having a substantially T-shaped slot extending therethrough for receiving the enlarged circular head of the left ear cup connector, the housing further provided with aligned, oppositely disposed cutaway portions on an upper portion thereof such that the cutaway portions are disposed above opposite ends of the substantially T-shaped slot.  
   
   
   
       5 . The earmuff having anatomically correct ear cups of  claim 4  wherein the first connecter assembly further comprises: 
 a plurality of spatially disposed rib members formed on the backside of the right ear cup so as to extend outwardly from the post and terminating substantially adjacent a perimeter of the substantially planar connecting area; and    a plurality of spatially disposed teeth formed in at least a portion of a lower surface of the housing, and the spatially disposed rib members and the spatially disposed teeth cooperating to permit axial rotation of the right ear cup about the post of the first connector assembly while stabilizing the right ear cup in a desired position due to meshing of the rib members with the teeth; and    wherein the second connector assembly further comprises: 
 a plurality of spatially disposed rib members formed on the backside of the right ear cup so as to extend outwardly from the post and terminating substantially adjacent a perimeter of the substantially planar connecting area; and  
   a plurality of spatially disposed teeth formed in at least a portion of a lower surface of the housing, the spatially disposed rib members and the spatially disposed teeth cooperating to permit axial rotation of the right ear cup about the post of the first connector assembly while stabilizing the right ear cup in a desired position due to meshing of the rib members with the teeth.
