Each has a different filter design shape: Reference (Black), Classical (Red), and Pop (Blue). By customizing with these three filters, you can enjoy your preferred sound style. 0.78mm 2pin Re-cableable: High-grade silver-plated cable adopted The cable uses OFC silver-plated wire in a Litz braid anti-oxidation structure, enabling superior transmission quality and more realistic signal transmission.
