HIFIMAN Jade II is an electrostatic headphone available either as a standalone model or as part of a complete system with the matching Jade II amplifier. That choice matters: electrostatic headphones require a compatible energiser/amplifier, so the headphone-only option is intended for listeners who already own suitable electrostatic amplification.
An ultra-thin electrostatic diaphragm
The Jade II uses a nanoparticle-coated diaphragm stated to be under 0.001mm thick. HIFIMAN positions this extremely low-mass driver as the basis for the headphone’s low distortion, rapid transient response and extended treble response. In practical terms, those are the qualities usually sought from an electrostatic design: speed, articulation and the ability to expose fine detail in well-recorded music.
The quoted frequency range is an unusually broad 7Hz to 90kHz, though, as always, a published bandwidth alone does not indicate how a headphone will sound across that range.
Lightweight construction for longer listening
At 365g, the Jade II combines an aluminium-alloy structure with soft earcups and HIFIMAN’s hybrid headband design. The aim is a secure but comfortable fit for extended sessions, rather than the heavy, tightly clamped feel that can make some high-end headphones tiring to wear.
The dedicated Jade II amplifier
The matching HIFIMAN Jade II amplifier is a stationary, mains-powered unit designed for 220V or 110V operation. Its relatively compact enclosure is intended to suit a conventional hi-fi rack or desktop system, making the Jade II a more self-contained route into electrostatic listening than assembling separate components.
The amplifier measures 276 x 270 x 116mm and weighs 6.5kg. Buyers considering the complete package should also bear in mind that electrostatic headphones cannot be connected to a conventional headphone amplifier; the dedicated amplifier, or another compatible electrostatic model, is essential.
Sound character: speed, separation and a lighter tonal balance
The listening notes describe the Jade II system as relatively neutral and balanced, with particularly strong speed, articulation and detail after several days of warm-up. Its tonal balance is characterised as leaner and cleaner than the Stax 007 MK2, and less warm than the MrSpeakers VOCE.
Midrange timbre is described as well judged, with good harmonic balance, ample separation between instruments and a very fast sense of pace. Those traits are said to support accurate, three-dimensional imaging rather than a thick or overtly romantic presentation.
At the low end, the Jade II is reported to deliver tight, punchy bass without an overbearing sense of weight. Compared with both the Stax 007 MK2 and MrSpeakers VOCE, the presentation is described as lighter and less warm, while retaining the speed needed to give rhythmic material impact when required.
Headphone-only or complete system?
The Jade II can be bought without its matching amplifier by owners of an existing compatible electrostatic amplifier. For most prospective buyers, however, the headphone-and-amplifier package is the more straightforward option, removing any uncertainty over compatibility.
The headphone’s performance may also vary with alternative electrostatic amplification and source components, but no conclusions are available here on its pairing with other amplifiers, DACs or non-standard system configurations.
