Why Does the Sound Quality Improve After Being Grounded?

When using a properly grounded 4.4mm headphones cable with a shielding layer, sound quality can be significantly improved, especially when paired with metal-clad devices such as the SONY NW-ZX706 and NW-ZX707. The metal-clad music player forms an effective shielding system when connected to the shielded 4.4mm headphones cable, reducing the effects of electromagnetic interference. This design optimizes the purity of signal transmission, resulting in a more immersive and detailed listening experience.
