Hifiman HE600 Headphones

A Modern Take on a Legendary Design

The HE600 reimagines HIFIMANs iconic HE6 with updated materials, refined engineering, and a more comfortable design. It aims to capture the power and dynamics of the original while improving day-to-day usability for todays headphone listener.

Reinventing a Classic Sound

The HE600 has been tuned to replicate the original HE6s energetic, detail-rich presentation. With a sensitivity rating of 94dB and a low 28-ohm impedance, it can be driven by a wider range of modern headphone amplifiers than the HE6, which notoriously demanded speaker-amp-level power. This lowers the barrier to entry without discarding the performance pedigree. However, at 94db, it means the HE600 still needs a decent amount of power.

Advanced Magnet Design

HIFIMAN introduces a rare-earth-free permanent magnet system in the HE600. Engineered to minimize distortion while preserving detail and dynamics, this approach also reduces reliance on rare-earth materials. Its a technical and environmental shift that delivers comparable control to neodymium-based designs.

Second-Generation NEO Supernano Diaphragm

The HE600s diaphragm is now just 60% of the thickness of the original HE6 membrane. This ultra-lightweight film improves transient response and fine detail retrieval, with faster attack and decay across the frequency spectrum. The result is more lifelike dynamics and improved resolution while maintaining the planar drivers signature clarity.

Comfort and Practical Design Updates

The original HE6 was known as much for its sound as for its weight. The HE600 trims that down to 389g, paired with HIFIMANs 2nd-generation composite headband for better balance and rotatable hinges that conform to different head shapes. Memory foam FocusPads wrapped in pleather and velour provide a secure yet breathable fit.

Connectivity also gets an upgrade: new 3.5mm connectors sit at a 10-degree angle to reduce strain on cables, ensuring longevity under repeated use.

What This Means for Listeners

The HE600 positions itself as a more approachable successor to the HE6: easier to pair with modern amps, more comfortable for long listening sessions, and still tuned for speed, dynamics, and fine detail. For fans of the HE6s legacy, it promises a faithful update with less compromise in usability.

*Notes: HE-6 specifications and connector style vary by early/late runs; sensitivity is widely reported around the low-80s dB and requires unusually high output. Arya Stealth figures are typical published values and may vary slightly by batch. For best results with HE600 and Arya Stealth, plan on a clean desktop amp with solid voltage and current delivery.
