Durandal

Durandal employs a unique triple-driver configuration, combining Sonion dual-membrane bone conduction drivers, a custom dynamic driver, and four balanced armature drivers. Through a meticulously designed 4-way crossover, the strengths of each driver type are fully utilized.

​This unique driver arrangement and crossover design allows Durandal to excel in both low-frequency performance and mid-to-high frequency resolution and detail retrieval. The mid-range and vocal presentation is naturally rich and full-bodied. For users seeking natural, lifelike vocal reproduction, powerful bass performance, and crisp, clear high-frequencies, Durandal is an excellent choice. The innovative driver setup and crossover engineering allow it to deliver a comprehensive and coherent sonic signature.
