Customer Review Summary
Introduction to the HIFIMAN HE 600
Released in October 2025, the HIFIMAN HE 600 presents a sophisticated option in the realm of open-back circumaural headphones. Positioned at £735, this model offers features aimed at audiophiles who appreciate detailed sound reproduction through a magnetostatic driver system. This review focuses solely on the product’s technical attributes and design specifications.
Design and Build Quality
The HE 600 is built for over-ear use, with an open-back architecture that allows air flow and a more natural soundstage compared to closed designs. The circumaural ear cups fully encompass the ear, improving comfort and isolating external noise passively to some extent despite the open system.
- Weight: At 389 grams, the headphones are moderately light, benefiting longer listening sessions without undue fatigue.
- Materials: The headband combines flexible steel and aluminium for both durability and a degree of flexibility, ensuring a balanced clamping force.
- Ear pads: Constructed from memory foam with a dual-layer cover of artificial leather and velour, these pads aim to provide comfort while maintaining a stable seal around the ears.
- Finish: Available in black and silver, the HE 600 sports a clean and professional aesthetic suitable for both home and studio use.
- Cable Routing: Featuring two-sided cable routing with replaceable cables, the design supports user convenience and longevity of use.
Acoustic Features and Performance Potential
The headphones deploy a NEO Supernano Diaphragm Generation 2 magnetostatic driver, operating within an impressively wide frequency range of 8 Hz to 65,000 Hz. This range extends into ultrasonic frequencies, useful for specialised listening or audio research environments.
- Impedance: The 28 Ohm impedance ensures compatibility with various audio sources, including portable devices, without the need for high-powered amplifiers.
- Sensitivity: Rated at 94 dB sound pressure level, the HE 600 offers efficient sound output at moderate volume settings.
- Open-Back Architecture: This design facilitates a broad and accurate soundstage, providing an immersive listening experience with better spatial cues.
Cabling and Connectivity
The package includes a 1.5 metre cable terminating in two 3.5 mm stereo mini jacks, along with a 3.5 mm to 6.3 mm adapter. The cables are detachable, facilitating straightforward replacement or upgrades. This provision increases the product’s lifespan and adaptability for different audio setups.
Summary
The HIFIMAN HE 600 combines robust construction with technical refinements intended for detailed and extended listening. Its open-back design and advanced magnetostatic drivers suggest capabilities well suited to critical listening in controlled environments. Although priced at a premium level, the attention to ergonomic details and the wide frequency response highlight its purpose as a precise audio tool rather than a casual headphone.
