Gosh, just about any modern comfortable headphones will work FB. Most low-cost phones have an impedance of about 50 ohms that works FB with the Elecraft rigs. For a long time, "hi-fi" phones had an impedance of about 8 or 16 ohms to be used with audio gear. The preferred impedance seems to have gone up with the popularity of portable music players such as the "Walkman".
Let's see, what's hanging on the phones jack of my K2 at the moment are some inexpensive Radio Shack phones, "Nova 56". I think they're about a decade old now <G>. I've got some inexpensive LabTek phones around here somewhere too... Actually, I think you'd find that the old WWII type phones wouldn't work. Most of those phones were very high-impedance: about 2,000 ohms. I've not tried them with any Elecraft rigs, but I think you'd find the audio level disappointing if you can hear anything at all! Ron AC7AC -----Original Message----- Can anyone suggest reasonably costing plain-vanilla earphones for ham use? What 2007 headphones are available out there - be it WMart, RShack, or Bose? What quality, not WWII vintage, earphones are good performers for K2, IC-706MKIIG, or IC-7000 type ham rigs? I'm not searching for Western Electric WWII headphones. I suspect there is one or 2 models out there, that we can all afford. What impedance am I looking for?
