While we're on a similarly related topic, has anyone done the Headsets Inc ANR mod of a DC 10-13.4?
Or are there other in-line ANR options? I'm keen to give ANR a go as I have a pair of Sennheiser PCX450s which are great when sat in the back of a shiny tube, but if I can mod the DC's it'd save some cash rather than stump up for a new ANR pair.
