Headset Interface Units provide maximum operational flexibility for a radio user allowing Headset or earpiece connections to one or two radios alongside remote or wireless PTT capability. They remove the radio(s) from the operatives chest and allow it to be secured elsewhere on the body for comfort, security or optimum propagation reasons. Rugged housings and efficient clothing attachments via clips or Klickfast studs place Headset Interface Units as essential where mission critical flexibility is a must.
