Furutech/ADL reveals the H128 headphone: signature smoothness with added ‘punch’

ADL (Alpha Design Labs), sister brand of Tokyo-based Furutech, unveils its second headphone, taking the smoothness and balance of the existing H118 and adding vividly increased dynamics.

“With these, our latest breakthrough headphones, we decided to take the performance of our now classic H118 headphones one step further,” said ADL. “We wanted to retain the H118’s smooth, well-balanced sound which has captivated so many headphone enthusiasts, but we also wanted to improve dynamics and recreate the same ‘punch’ that you hear during live performances – a lofty goal for a pair of headphones.”

To accomplish this, the brand’s engineers designed and developed a completely new driver from scratch in collaboration with colleagues at parent company Furutech and with input from an external team of renowned Japanese audio experts.

The H128 is a dynamic closed-back circumaural headphone. Its tailor-made diaphragms offer both high noise attenuation and low distortion, and feature high quality PEEK film with a specially designed surface selected for extraordinary performance. Furutech’s ‘Pure Transmission’ technologies abound: 40mm highresolution extra-large high-flux neodymium drivers magnets; an aligning ring engineered to ensure phase coherence in ultra-high frequencies; rhodium-plated mini XLR sockets; all-OCC internal wiring, and excellent transient response from extremely lightweight coils made with copper-coated special aluminium alloy wire.

All of the drivers’ metal parts are ‘Alpha-Process’ treated1 , a low-temperature twostage cryogenic and anti-magnetic process that significantly improves every facet of audio performance.

The H128 also features Alpha Triform Contour EarcupsTM which are specially designed for a superior seal over the ears, improving bass response over other designs. The Triform Contour also reduces internal standing waves and reflections for reduced distortion.

Included in the ADL H128 package are two Furutech headphone cables. Pair the H128 with ADL’s award-wining GT40α (Alpha) USB DAC/preamplifier, their A1 or X1 portable headphone amplifier, or any other high quality headphone playback system to experience a new dynamic intimacy with your music.

1 Furutech’s Two-Step Alpha Cryogenic and Demagnetizing Process

Using cutting-edge technology and materials, Furutech’s Alpha-Process is a twostage procedure of (i) deep, conditioning cryogenic freezing of metal parts to relieve internal stress, enhance molecular bonding, increase stability and improve electrical conductivity, followed by (ii) a patented ring demagnetization treatment of the same parts which uses controlled attenuation to completely eliminate magnetization.

Almost metallic parts used in Furutech products go through the Alpha-Process to ensure that they are in a perfect stress-free, stable and highly conductive state.
