I'm not smart enough to change my habits or headsets if a Fed or company line check guy show up, so I stick with by-the-book on everything I can. Is it irrational fear to think an unapproved comm set-up could get me in trouble? I was once chastised by a Fed in a single pilot 135 op for placing a sunshade film on the windscreen; Fed "where's the TSO stamp on that shade?" Me: "burned off by brutal sun rays that would have scorched my corneas if not for the dark film protection." He was serious and was not amused. Then I turned due east into a harsh early morning sun and asked him which was safer for my operation, with or without said unapproved airplane accessory? I also let him hand fly and land the mighty Navajo, and he forgot all about the TSO B.S. The point is, there are people who care about such petty matters. I assume UFlyMike and the consumer-grade Bose have not caused you any grief?

Thanks to all who share their 220 headset thoughts.
