HiFiMAN HE600 – open-back planar magnetic headphones with Neo Supernano Gen.2, lighter headband and natural high-resolution sound.
Planar Magnetic Headphone
The HiFiMAN HE600 is a refined evolution of the iconic HE-6 — featuring a Neo Supernano Gen.2 diaphragm, a newly developed magnet system without rare-earth materials, and a revised, lighter aluminium headband.

The second-generation diaphragm delivers faster transients, increased micro-dynamics, and higher resolving power across the entire spectrum.

The newly engineered magnet structure reaches sensitivity levels comparable to classic rare-earth designs — without using rare-earth materials.
Lighter FocusPad ear pads and a redesigned headband reduce overall weight and improve comfort for long listening sessions.
Standard 3.5 mm sockets — compatible with a wide selection of aftermarket cables.
Not a simple reissue: HE600 implements HiFiMAN’s latest engineering generation and delivers a natural, transparent, highly resolving sound.

Frequency response
The line marked as target is something you could call the “ideal” curve: a target response derived from research by the Harman group, exploring what kind of headphone tuning tends to be preferred by a broad range of listeners – regardless of age or demographics. This is often referred to as the Harman Target.
From left to right you see sub-bass, bass, mids, and then the curve tilts upward where treble begins. That part of the spectrum is naturally amplified by the shape of the human ear.
Sub-bass sits clearly below the target – common for open headphones, the Harman target includes a strong bass shelf, the bass is slightly reduced. The lower mids are neutral, the presence region around 3 kHz hits the target. The treble is slightly tuned more relaxed – never sharp, easy over long sessions, and the range above 10 kHz stays on the curve. Left and right channels track each other closely, a sign of careful driver matching.
