This 4.4mm jack connector with a neat carbon finish. is built with gold-plated brass conductors within a painted metal capsule. It offers good conductivity and mechanical resistance.

Its structure is TRRRS (Tip - 3x Ring - Sleeve). It can thus be used to build a very compact balanced connector.

The base of the cable.is protected thanks to a silicon sleeve that protects the cable conductors against twisting and strong pull.
