Against the recent AUD comps, A$650 is well above the market: it sits far past the A$417 75th percentile and nearly A$300 over the median A$353, so this is an ambitious ask rather than a fair-price listing. It would need exceptional condition, extras, or warranty cover to justify that gap.
The EF400 is a respected all-in-one desktop unit, with a reputation for strong current delivery and a clean, powerful presentation that suits planars and demanding dynamics well. If the box is complete and the unit has been lightly used, that’s a plus, but at this price a buyer should be picky about included power supply, remote, and any signs of heat or output-stage issues.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Hifiman traces its origins to 2005, when Dr. Fang Bian, a chemist with a lifelong passion for audio electronics, founded Head-Direct in the United States as an online retailer and headphone developer. By 2007, he rebranded to Hifiman, relocating manufacturing and R&D to Tianjin, China, while maintaining sales operations in the US and beyond. This fusion of American entrepreneurial drive and Chinese production expertise propelled the brand from modest in-ear monitors to global prominence.
The company specializes in high-end headphones, particularly planar-magnetic and electrostatic models renowned for their detail and soundstage, alongside complementary portable digital audio players, headphone amplifiers, and cables. Early milestones like the 2009 HM-801—the first pocket-sized high-resolution player—and the HE-5 planar headphones established its innovative edge, with co-founder Binwu He pioneering planar technology integration.
Hifiman commands a elite position in the audiophile market as a high-end leader, delivering reference-grade performance that rivals legacy brands. Its products earn consistent acclaim for transparency and musicality, appealing to discerning buyers seeking uncompromising planar transduction without vintage pretensions or mid-tier compromises.
