Tactical Headsets (TTH & TTH Series 2) are active noise
reduction (ANR) communication headsets intended to be used by military
passengers of wheeled combat vehicles. The TTH headsets include an earcup
assembly (earcups and napeband) and a cable/microphone assembly. The
headsets adjust to fit various heads using adjustment overhead hook and loop straps
to ensure proper fit for noise attenuation. The cable/microphone can be installed on
either the left or right earcup.
In addition to passive attenuation each earcup contains an independent ANR
system. The ANR system reduces background noise within each earcup. The talk-
thru circuit (TTC) allows for local communication when the headset is either
connected or disconnected from the vehicle. The TTC is a user-selectable feature
and is powered via a single AA size battery in the control module and utilizes the
microphones on the front of each earcup. Each earcup has an independent TTC to
allow left/right localization.
