This A$650 asking price is ambitious for a used Hifiman EF400, sitting well above the median of A$353 and the 75th percentile of A$418 from recent AUD listings; it exceeds the top end of the typical used market by roughly A$232. While the unit includes accessories and is listed as used, the price does not reflect the strong depreciation this model has seen, with new open-box units often dipping near A$470–A$590 depending on sales.
The EF400 remains a well-regarded R2R DAC/amp prized for its Himalaya R2R architecture, delivering musical warmth and low distortion (THD 0.002–0.004%) alongside 4.4W balanced output. It’s a solid upgrade path from older entry desktop amps and offers fully balanced design with multiple outputs. However, at A$650, buyers should verify condition details, original ownership, and included cables to ensure there’s no hidden wear or missing parts that would justify this premium over the market median.
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.
