The HD600 headband utilizes a perforated mesh material to aid in breathability to help keep the top of your head cool. Backing this is the segmented design, with spacing between each individual pad allowing for more open air, as well as a channel to allow the headband to flex into place without issue. The foam inside is our high density memory foam found in our Elite and Choice Series.
Our replacement headband fits the following models from Sennheiser: HD58X, HD600, HD650, HD660, HD 660S, and the HD6XX.
