The timing matters a bit here because the EF400 is an older value play in Hifiman’s desktop lineup, so you want the price to reflect used-market reality rather than “current model” thinking. At A$650, it is clearly above your recent comparable cluster: the median is A$355, the 75th percentile is A$419, and this listing is not just ambitious but well beyond that range.
What still makes it interesting is the EF400’s reputation as a strong-sounding, all-in-one desktop amp/DAC with plenty of drive for demanding headphones and a notably distinctive presentation for the money. If it’s genuinely clean, includes the original PSU and accessories, and has been trouble-free, it can still be a solid buy for someone who wants Hifiman’s house sound and a neat compact setup—but at this price, I’d only move if condition and provenance are especially good.
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.
