Do you own many headphones? Do you own more than one amplifier? Do you want the best headphone cable around for each one while saving space & money? C3 Audio Universal Headphone Cable system takes your whole audio system to the next level.

SKU: N/A Category:


Are you devoted to your high-end headphone collection but tired of purchasing a new cable each time you buy new gear? Now you don’t have to. Our unique headphone cable system allows you to easily switch between your headphones and amplifiers with the same cable.

The C3 Audio Universal Headphone Cable is the first and only product of its kind. Other manufacturers use small adapters with already-existing standalone cables. Depending on the headphone type, these adapters may not even be available due to plug design and proprietary technology. The C3 Audio system is different because it’s designed to plug & play. It achieves full universal compatibility from end to end while maintaining consistent standards among all product lines. No other product can give you the flexibility and usability that this system offers.

This cable is made using the same in-house UPOCC wire found in our industry-leading UPOCC headphone cable. Headphone aficionados can bring unmatched performance to all of their audio gear while saving hundreds of dollars and improving organization and system continuity.
