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. 73, Jim N7US -----Original Message----- 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. ED / W2RF -----Original Message----- 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. 73, Gary KA1J > > I have Bose QC-35 headphones.
