It’s been suggested that North Korea leader Kim Jong-Il gave the coach advice on how to reach the World Cup. Kim Jong-Su, the general secretary of the North Korean FA, has said the ‘Dear Leader’ gave “in-depth guidance” on how to develop the game in the country and the coach himself has claimed he received regular tactical advice during matches, ***apparently using mobile phones that are not visible to the naked eye. Jong-Il is said to have developed the technology himself. ***
Well, I suppose some form of earpiece and mike like secret service types have. I suppose you don’t need the thickish curly cords running up behind the ear, you could use fairly small gauge wires. Can bluetooth type tech be made small enough that the earpiece doesn’t need wires? If you dont need a mic boom then you don’t need the external part pf the bluetooth headset.
I think the idea is that it’s another outlandish claim about the Dear Leader’s amazing achievements, not so much as speculation on how it could be done.
