[Elecraft] K4 Headphones Q

[Jim McDonald]

I just bought a pair yesterday at a closeout price of $170 from my local Costco.  They have been discontinued.  Costco online is now out of stock, but some stores still have them.  Amazon has them for $199 now.

My favorite headphones up to now has been Sennheiser HD 280 PRO but these sound great and eliminate the noise from my KPA1500 with the fan on #2 and a nearby water heater fan.  No comparison with my old QC2 headphones.

I also use a QC-35. When plugged in with a cord, the power must be on for the noise cancelling to work. That also turns on the DSP which greatly improves audio quality.

Jim,

I only use my Bose QC-35 when:

1. on the cell phone.
2. mowing the yard/tuning my motorcycle
3. whenever using the K3 & K3s. 

The noise cancelling works perfectly with the blower from the Alpha 77SX right next to me, I only hear what is coming in from the radio. Why your
QC-35 does not noise cancel when attached via cord is not normal, mine is a Godsend.
