Dekoni Audio has been hard at work on pads for the HiFiMan HE series headphones. While these only fit the round models such as the HE5, HE4, HE400i, HE400s, HE500, HE560, and the Susvara you will find them to be a huge upgrade to both the confort and sound of the headphones. With 4 different variants to chose from you also have the ability to tune the headphones to your own tastes by varying the pads you use. This ear Pad model fits the HE5, HE4, HE400i, HE400s, HE500, HE560, and Susvara This model features Dekoni's carefully measured Fenestrated Sheepskin. What makes the fenestrated sheepskin so special is that it was designed to be as neutral as possible when letting sound pass. It does not absorb so much as to leave your headphones sounding anemic nor does it let so much of the reflections pass that you get buildup of any frequencies. You get the True sound of your headphones.
