---------------------------------------------------
【Voltage Compatibility】
Our products are selected to support international voltage ranges (e.g. 100–240V).
However, please make sure your local voltage is compatible before use, as incorrect voltage may still cause malfunction.
【Plug Type】
Our products use Japanese plug types (A or B type).
Please use a conversion adapter if necessary.
【Important Note on Transformers and Adapters】
A transformer adjusts voltage to match your device’s requirements.
A conversion adapter only changes the plug shape and does not adjust voltage.
Using only a conversion adapter without a transformer may result in damage to the product.
【Liability】
We are not responsible for malfunctions or damages caused by improper use, such as operating the product without appropriate voltage or equipment.

HIFIMAN's UNVELLED, which debuted in 2024 with the reference model "SUSVARA UNVELLED," literally means "removing the grille that can hinder the movement of the nanometer-thick diaphragm." By doing so, the soundstage widens, depth increases, and a very pure audio experience is delivered. Harmful reflections and refractions of sound waves react to the diaphragm. Sound waves are emitted. Sound waves are reflected by the grille and return to the diaphragm. The diaphragm is affected, and the sound quality deteriorates.
Typical Commonplace headphones use a low-aperture mesh as a grille, which causes reflections and refractions that degrade sound quality. Because the diaphragm, with its nanometer thickness, is extremely lightweight, it is easily obstructed by sound waves reflected and refracted by the mesh. Therefore, HlFlMAN uses a window-shade design to increase the aperture ratio, maximizing grille exposure and reducing the potential for reflection and refraction. The result is a dramatic improvement in sound quality.
Window shade designs cannot completely avoid reflection and refraction. Only by eliminating the window shade/grille design can near-lossless sound quality be achieved.
Magnetic veil. Specifically designed to protect the fully open drivers of the ARYA UNVEILED. *Due to the magnetic properties of the drivers, it is important to cover the earcups with the magnetic veil when the product is not in use to avoid damage from absorption by magnetic objects.
Core Technology - Nanometer HIFIMAN Thickness Diaphragm. Low distortion, high transient response, and overall improvement in dynamics and detail. The ARYA UNVEILED diaphragm is less than one millionth of a meter thick. Extremely lightweight, it provides headphones with extremely fast response speed and exceptional dynamic range and frequency characteristics. Combined with "Stealth Magnet" technology, the nanometer-thickness diaphragm material is essential for clear and fatigue-free sound output, even after hours of listening.
Acoustically invisible stealth magnets. The special streamlined cross-sectional shape of stealth magnets optimizes and reduces airflow and diffraction between magnets, allowing sound waves to pass between them with almost no impact, without compromising sound quality as with conventional magnets. Unlike the sound waves generated by conventional magnets, stealth magnets can be thought of as disappearing in front of sound waves, reducing much of the negative impact on sound.
Specifications: Frequency response: 8Hz-65kHz, Sensitivity: 94dB, Impedance: 27Ω, Weight: 413g (excluding magnetic veil and headphone cable)
