Fostex AMS-TH1100RPMK2 Premium Open-Back Planar Headphones (B-Stock)

Overview

The mk2 flagship RP headphones are carefully assembled one by one at a factory in Japan. The beautiful indigo color and texture of the wood grain of the housing, hand-dyed by skilled Awa Indigo craftsmen, combined with the overwhelming resolution and faithful expression of the premium RP drivers, provide an exquisite audio experience in which traditional craftsmanship and acoustic technology coexist.

The Premium RP Driver, developed using the largest diaphragm ever used in a fully driven planar diaphragm driver based on RP technology that has been refined since 1974, has been further optimized with mk2 technology through air damping control inside the driver, flow ad-justment using damping materials and new ear pads. This achieves ideal diaphragm amplitude, particularly in the low-frequency range. The Premium RP Driver’s large diaphragm and mag-netic circuit suppress unwanted resonance, delivering sharp response, high sensitivity, smooth frequency characteristics, and excellent transient response. Additionally, the mk2 version achieves the ability to faithfully and clearly reproduce sound images from the low-frequency range to the high-frequency range in space with precise localization.

The newly adopted ear pads in the mk2 feature a sloped design on the side that contacts the face, optimizing comfort. The internal low-density urethane foam is arranged in a two-layer structure, with a soft type on the outer side and a high-elasticity type on the inner side to con-form to the shape of the face. Additionally, the adoption of silk protein-based synthetic leather, which offers three times the durability of the previous model, ensures comfortable wear even during extended listening sessions.

The mk2 version uses a 2-pole 3.5 mm connector, improving re-cable compatibility and versatil-ity. The internal wiring and included unbalanced cable utilize 7N (99.99999%) grade high-purity OFC (Oxygen-Free Copper) cable, which minimizes impurities to maximize transmission per-formance. Additionally, a separate 4.4 mm balanced cable (ET-TH4.4BL2Y) is available for purchase.
