My personal unit in pristine condition—top-tier audio quality, no cheap compromises!Core material: Custom-made using wire from the premium "Noble Audio Magnus" cable (featuring graphene conductors); original value was over $1,200!Function: This short adapter allows for the direct connection...
Noble’s Magnus 4 is a premium aftermarket cable associated with the brand’s flagship in-ear designs, rather than a conventional pair of headphones. At US$315, this is a strong bargain against the three comparable listings: it sits well below the US$640 25th-percentile price and is roughly one-third of the US$965 median. Even allowing for the unknown condition, the asking price looks unusually attractive.
The appeal is its high-end construction: a graphene/silver-based four-core design, premium 0.78 mm two-pin connectors, and a balanced 4.4 mm Pentaconn termination. It makes most sense for someone already using a compatible Noble or other two-pin IEM and wanting a substantial cable upgrade without approaching typical used-market money. Confirm that the connectors and plug are sound, and that the cable is genuinely the Magnus 4 rather than a visually similar Noble cable; if those checks pass, this is an easy buy.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Noble Audio was founded in 2013 by audiologist Dr. John "Wizard" Moulton, a pioneering figure in custom in-ear monitors with roots tracing back to his earlier work at Heir Audio. Based in the United States, the company emerged from Moulton's expertise in audiology and IEM design, honed over years in Thailand and beyond. In 2018, his brother Jim Moulton joined as 50% owner, propelling the brand's expansion while preserving its artisan heritage in precision audio engineering.
The brand specializes in high-end in-ear monitors (IEMs), offering both custom-molded and universal-fit models renowned for multi-driver configurations, such as the groundbreaking 10-driver K-10 and flagships like the Viking Ragnar, Ronin, and Kublai Khan. Noble has diversified into true wireless earbuds (TWS), debuting the award-winning Falcon Pro in 2020, followed by the FoKus series—including the all-wood Prestige and models like Mystique, Triumph, and Apollo—blending audiophile tuning with cutting-edge wireless tech.
Positioned firmly in the high-end audiophile market, Noble commands respect for its technological innovation, award-winning sound signatures, and meticulous craftsmanship, earning multiple Headphone of the Year honors. It appeals to discerning buyers seeking reference-level portable audio, standing out as a boutique leader against mass-market competitors through superior detail retrieval and customization.
