  We study the anisotropic Kondo line defects in products of chiral $SU(2)$ WZW
models. We propose an ODE/IM correspondence for the anisotropic Kondo problems
by considering the four-dimensional Chern Simons theory in the trigonometric
case. We verify the claim both by explicit perturbative calculations in the
ultraviolet and by exact WKB analysis in the infrared. In doing so, we derived
the infrared dynamics of a large class of anisotropic line defects.
