Brano Meres, a Slovakian industrial designer and engineer says of his Bluetooth-equipped Red Army phone:
This is the first Soviet army phone from the 1960’s to be equipped with Bluetooth technology. It was intended for use as a Bluetooth headset with my mobile phones. To redesign this phone, Titanium and high quality wires from dismantled Scud missiles were used.
The phone is equipped with a multifunction button (Power on/off, answer/end calls), volume up/down button, two LED indicator lights and a connector for charging the battery.
