Noble Audio Katana Universal Headphones - In Ear Monitors Noble Audio Katana 9 balanced armature driver in ear monitors. Bought years ago from Addicted to Audio for portable use, but ended up not using it much as I don't have the opportunity to listen on the go. Neutral & clear sounding, sounds good with any genre. Plenty of rave reviews online. Comes with everything bar one set of tips which I've used. If you want a package deal with the Effect Audio Eros II cable also for sale just let me know and we can work something out. Condition: As New / Mint Payment Method: PayPal, EFT, Cash on
A$1,000 is above the median but still within the normal used range for this model, so I’d call it fair to slightly firm, not a bargain. Against your comps, it sits well above the A$715 median and just under the A$1,078 75th percentile, which means the asking price is toward the upper end without being out of line.
That still makes sense if the condition is genuinely like new and the set is complete, because this is one of Noble’s better-regarded high-end in-ears: resolving, fast, and capable of a very clean, articulate presentation with strong separation. The upside here is paying for a well-kept, premium piece rather than taking a gamble on a worn unit, so if the fit works for you and the accessories are intact, it’s a credible buy rather than a stretch.
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.
