About this detail of the Tiger
German panzer crew had headphones and throat microphones, both for communication within the tank and by radio. In the turret of the Tiger 1, the commander and the gunner used them. The loader, who crawled around the tank fetching ammunition, was not provided with communications gear or a network socket.
There was a standard box for holding one set of headphones and microphones. It was used in many Panzers. This example is in the Bovington museum Tiger, and has its original paint and decal. Two of these boxes were fixed inside the Tiger's turret.
The box had a lid and was internally padded. The diagram shows its dimensions.
At the start of Tiger production, it seems that each headphone box was bolted to two horizontal brackets welded to the wall. This gave it some protection from impact shocks, which later proved inadequate. This photo is from the American museum Tiger #250031 which was overpainted post-war. The brackets are indicated (this box is partially detached).
The tank's stowage was redesigned in December 1942  , with the addition of metal strips for better shock protection. The resulting layout is preserved in the Bovington museum Tiger. Both of the headphone boxes were now placed high up on the rear wall, straddling the left-hand roof beam.
I believe that Befehlstigers of this period had the boxes in this place also.
Turret stowage was greatly simplified in late 1943. The headphone boxes were without lids from that time forward. They were fixed to the inside of open storage bins that were now present on the turret ring. This example is in the Saumur museum Tiger  . Some of its original ivory paint can be seen at the bottom.
