A metal blend that defies both gravity and abuse, E Wire® 2.1 is decked with refined bridgework and mounted with enhanced earstems that are held comfortably in place by the stable tension of a spring hinge mechanism. Iridium® lens coatings tune contrast for any light condition while patent XYZ Optics® maximizes peripheral clarity. Soft Unobtanium® earsocks increase adhesion with moisture to maintain the comfort of a secure fit.
