[Elecraft] Headphones

[Macy monkeys]

That's a bummer. The wired Bose QC25’s show no signs of RFI while running my KPA500. I even bought a spare pair of QC25’s when the price was right. I do go through a few batteries...maybe two a month. The noise cancelling sure wipes out all ambient room noise, amplifier fan noise, TV, and conversations from an adjoining room. Very happy...

I have tried several toroid chokes, even one close to the ear piece -- no help. On 40m, I have the problem at power levels ranging from 5 to 1200 w. Too bad, they fit and sound great.
