Arrange excess lengths of your car aux cable in “S” or “8” coils and not in loops. Loops produce electromagnetic interference, while an “S’ or “8” coil minimizes interference.

Clean dirty jacks with a mild cleaning solution applied to a soft cloth. Dirt and grime produce a scratching sound on the audio and promote wear and tear on the connector.
