Know before you buy
The long-term natural annealing process helps to stabilize the copper's crystalline structure, which reduces internal stress and impurities. This results in a cleaner, more fluid signal transmission that translates to a more natural and refined sound signature.
The Sevenfold Pipe structure is designed to balance electrical performance with physical ergonomics. Despite the high-purity copper, the cable remains flexible and lightweight, making it comfortable for long listening sessions without excessive microphonics.
This cable features a standard 0.78mm CM 2-pin connector, which is compatible with a wide range of universal and custom IEMs. Please verify that your specific IEMs use this 2-pin interface before purchasing.
OCC Copper Litz is known for providing a warm, balanced, and organic sound profile. You can expect improved clarity in the midrange and a smoother, more controlled high-frequency response compared to standard stock cables.
Yes, the 4.4mm plug is a balanced termination. You will need a digital audio player (DAP) or a dedicated headphone amplifier that features a 4.4mm balanced output jack to utilize this cable.
