In this article, we prove some relation-theoretic results on coincidence and common fixed point Stereo Earphones for a nonlinear contraction employing a locally finitely T-transitive binary relation, where T stands for a self-mapping on the underlying metric space.Our newly proved results deduce sharpened versions of certain relevant results of the existing literature.Finally, we adopt some examples Bang Bang to substantiate the genuineness of our proved results herein.
