The ADL H128 headphones give you rich tonal colors and textures with intimate and close harmonic interplay.

A sense of space and quiet backgrounds are the key.  ADL has taken the performance of the now classic H118 headphones one step further.



The H128 retains the H118’s smooth, well-balanced sound that has captivated so many headphone enthusiasts, but ADL wanted to improve dynamics and recreate the same “punch” that you hear during live performances—a lofty goal for a pair of headphones.

ADL designed and developed a completely new driver from scratch with the help of engineers at Furutech and sound tune the headphones with input from a team of renowned Japanese audio commentators.

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