I was starting to have problems on the radio with the company ANR's, especially with female controllers. The Bose were better but clunky and hard to hear the other guy. I finally got a custom ear mold and an old school Plantronics from Averysound. Less than $300, I can turn down the volumes on the radios and I stick a earplug in the other ear during cruise. Way better than any other ANR combination. If we had hot mike on the intercom, I might feel differently. I'm on the 75/76.
