HiFiMAN HE-6
HiFiMAN’s legendary power-hungry flagship: fast, neutral, and ruthlessly detailed, if you can drive it.
Our take
The HE-6 is the one that famously needs a speaker amp: brutally inefficient, but in return a fast, neutral, highly resolving planar with iron-fisted bass control. Underpower it and it’s lifeless; feed it properly and few headphones match its grip. Not a casual purchase.
Measured on a Head Acoustics HMS II.3 artificial head — raw response, left/right averaged, normalized to 0 dB at 1 kHz. From the Sonic Temple Archive(2008–2014, one unit per model). Honest limits: seating variance runs ±0.4 dB in the mids to ±3.9 dB above 12 kHz, and open headphones read bass-light on this fixture — don’t read fine treble detail as settled. How we measure →
Common questions
Straight answers — the same ones our measurements support.
Does the HiFiMAN HE-6 need a special amp?
Effectively yes. It is so inefficient that many run it off speaker taps. A strong headphone amp is the minimum.
Is the HE-6 worth the hassle?
Driven properly, it is a reference for speed and control. Driven poorly, it is a paperweight.
