[Elecraft] K3 - 'High Isolation Headphones'

Hey Art, 



Do you have a source of the Sennheiser phones for $30?  Cheapest I can find is more than 50. 



Thanks, 



Tom, ng3v

I was using a Heil Proset noise cancelling. These headphones cancel just 
about everything. Amp noise, XYL, doors, barking dogs....you name it. 
But. After a couple hours or so my floppy ears start to notice they're 
being compressed into my skull. Ditto my Sennheiser HD400 headset except 
these are much lighter so it takes a bit longer to get that squeezed 
feeling. 

Seeking a solution I tried Sennheiser CX300-2 button phones, about $30. 
That is the solution for long term use! Noise blocking is excellent, 
just behind the ProSet. No squeezed ears. Excellent audio quality. 
They're a bit more sensitive than either headset so I turned the K3 to 
low audio. I also reduced the max audio clipping level in the K3. What a 
difference! Should have done this 30 years ago.
