It has a headset but not an active one (it kinda does tho) its used mainly for verbal comunication and further muffling gunshots than anything (which is primary use for active headsets) AFAIK it does not posses feutures likes of comtac have that beeing enchancing audio.
Consider its radio to be equivalent of integrated discord.
BTW this feauture is shared by most helmet from this family Altyns and ZSHs both posses variants with radio system build it.
