George Davies, head of cameras, Sky News, said that, given the microphones and cameras had to be used worldwide, sometimes in hostile environments, it was the equipment's physical toughness that had primarily informed the broadcaster's choice.
"Robustness and reliability come first," he explained. "Sennheiser kit is made from metal and is therefore heavy duty. It is also capable of reasonably high-powered output which is important to us, as our journalists want to do walking, talking pieces to camera and sometimes start fifty yards away."
Sky News is currently using the Sennheiser equipment in Washington, Delhi and Brussels. Over the last six months the broadcaster's three travel kits, based in London, have already been used to cover stories around the world - from the American elections and the Arctic to Iraq.
