ADL By FURUTECH H128
ADL By Furutech H128 supra-aural hi-fi headphones, designed for listeners seeking precise, comfortable audiophile listening.
Description
The H128 is a hi-fi headphone from ADL By Furutech, designed for close, demanding music listening. This type of device highlights the slightest flaw in the audio chain or in the headphones themselves, which explains the care taken by the manufacturer over every component.
The H128 features 40 mm high-resolution transducers, with so-called "high-flux α" motorisation and Alpha cryogenic treatment. Their diaphragms are made of PEEK, a technical thermoplastic known for its rigidity and lightness, paired with copper-clad aluminium alloy voice coils to limit moving mass. A dedicated ring maintains phase coherence in the ultra-high frequencies, promoting a precise transient response.
The Alpha Triform Contour ear cushions aim for a better seal around the ear, which improves low-frequency reproduction and reduces internal standing waves as well as spurious reflections, sources of distortion. The headband, made of aluminium covered in soft leatherette, is designed for extended comfort.
These headphones are aimed at listeners seeking refined audiophile listening, able to appreciate rich harmonic textures and a spacious sound image, for portable or home use on a hi-fi system.
What to check before buying used
On the Alpha Triform Contour ear cushions, check that the foam is neither compressed nor cracked, as a degraded seal immediately reduces bass performance and lets in unwanted noise. Also inspect the leatherette covering on the headband, which can crack or peel over time, as well as the flexibility of its hinge. Finally, test each transducer separately by ear to rule out any level imbalance or crackling between the two earpieces.
