The superior headphone housing used in the AH-D2000 to produce high quality sound is made of materials yielding exceptional acoustic characteristics ensuring faithful reproduction of the original sound. Compound metal is used to increase density, making the sound more stable and clear.

Microfiber material has been used to form the diaphragm so that it faithfully reproduces the sonic details and delicate reverberations that occur in concert halls. The size of Microfiber is approx. 1/100 of natural cellulose used in ordinary diaphragms, and its density increases transmission rates.

Optimum acoustic characteristics are achieved by adjusting the sound pressure balance in front of and behind the diaphragm with the Acoustic Optimizer design. To provide a sonically clean performance, a balance of low to mid range frequencies is critical and dynamic clear bass is a must; the Acoustic Optimizer delivers both.

High-quality cables made with 7N-OFC copper of equal lengths for the L/R channels are used to maintain optimum sound quality. A cloth mesh jacket is employed for cable protection and durability, and it is terminated with an aluminum covered connector plug for strength and performance.

A light-weight magnesium frame has been used so that listeners can enjoy maximum comfort during extended listening sessions.
