Dekoni Audio has finally released pads for the HE Series of headphones from Hifiman, offering a huge upgrade to both comfort and sound to a diverse line of great Hifiman models. Tuned to the HE400 series, Dekoni designed these pads to improve comfort and isolation, all while offering a variety of options for tuning the sound to your taste. When you take soft, supple sheepskin and wrap it in dense, slow rebounding memory foam, you increase isolation, comfort and sound stage.
