With the C3 Audio Silver-Plated Oxygen-Free Copper headphone cable, you have the best of both worlds: the bass power and performance of copper with the treble articulation and detail of silver. SPOFC improves sound signature performance on headphones with boomy and bloated bass, undesirably dark presentation, or vailed sound signature. This is also a great choice for anyone who prefers the sound signature of silver but doesn’t want to spend a small fortune on pure silver cables.

Like our similarly designed OFC headphone cable, our SPOFC headphone cable brings you industry-leading ergonomics, portability, and style.

If you’re ready to bring high-end performance to your audio system, C3 Audio’s SPOFC headphone cable is for you.
