An oxide film (rust layer) is an insulator. Dust and oxidation corrosion of the audio signal connector will affect your audio interface, resulting in poor contact or unstable contact, especially the working ground wire, which will affect the sound quality of the audio and produce bad noise. The RCA rubber cap can prevent dust and oxidation, so that the idle RCA signal lotus plug will never rust and maintain good contact.
