Has anyone tried wireless headfones such as these with their K2? http://www.radioshack.com/product.asp?catalog%5Fname=CTLG&product%5Fid=33-1219 I am curious how they handle being around a transmitting ham radio. The idea of being able to walk into the kitchen to refill a cup of coffee without losing half the QSO is appealing... tnx, Fred kt5x
