Velour Replacement Ear Pads for HiFiMan Headphones. Dekoni Audio has 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. Dekoni Audio spent a lot of time designing and refining this ear pad to be the most comfortable and best sounding velour pad available today. By using a tighter velour, Dekoni made the ear pad react more like traditional leather so that you don’t lose the bass frequencies or isolation seen in most velour pads, all while retaining the comfort and coolness of velour.
