In addition, the headphone’s drivers are protected by a newly designed casing for enhanced durability and protection from the elements. HE400se’s beveled hybrid earpads also contribute to the headphone’s exceptional performance. With this design, varying thicknesses conform to the human skull, almost as if it is custom-tailored to each listener’s head.
