Bose qc15 and u fly. Qc25 and u fly, clarity aloft, and Bose a20s are what I see most. Some telex, Some lightspeeds. All work fine. I prefer Bose with u fly. It doubles as a media/workout headset, as well as noise cancelling for those loud hotels. Don't think anyone has been hassled ever about TSO. If it's a known headset brand, you are good.
