QC 35 II - lots of noise during phone call
I recently got the Bose QC 35 II headphones, and I'm observing a lot of noise when on a phone call in a public setting (terrible when on the airport & in the bus). More than the people talking, it's a "grinding" kind of a sound that shows up most often. The headphones gave a better call experience when they were plugged in through the AUX cable in those settings instead (had to turn them off). Shouldn't the headphones be giving a better call experience when wireless & turned on rather than when wired & turned off?
