Bluetooth feature on an over the head module is great. Can have comms without radio attachments, still hear surrounds, noise cancelation if necessary, DB rating is as sufficient as other are. Only single complaint is the bulk. If I wanted to mount the to a helmet with ops core amp arms I think they would be to large. Additionally other color ways would also be a great market. FDE, camo or coyote etc.
All around great set of ear pro capable of all the normal use and needs
