HiFiMan HE-400i Headphones - Over/On Ear https://hifiplus.com/articles/hifiman-he-400i-planar-magnetic-headphones/ Bought these excellent planar headphones new. In perfect condition with all original packaging and accessories. Condition: As New / Mint Payment Method: EFT, cash on pickup Region/State: (NSW) New South Wales/Australia By Audiowolf 0 Comments Secure Ad AUD $300 Date: October 25, 2025Oct 25
Timing matters a bit here because the HE-400i is an older, discontinued planar model, but at A$300 it’s priced well above the current used run-rate. Against your local comps, that sits far beyond the A$143 75th percentile, so this is ambitious rather than fair value.
What still makes it interesting is the sound: the HE-400i is widely liked for its open, spacious presentation and that easy planar detail retrieval, especially if you want a relaxed but resolving listen. A like new unit is the right kind of condition to target for a headphone this age, but the price only makes sense if it truly includes strong extras or has been substantially refreshed; otherwise, buyers can usually do much better around the middle of the used market.
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.
