1. Bose X, with a powered adapter cable usable with standard plug jacks, in a carry case. I'm thinking $350. 2. Trusty David Clark H10-13.4. Fairly new gel ear seals. Fairly new boom mic foam cover but you will have to replace the twist tie with a rubber o ring clamp if you must. I'm thinking $150. 3. From what I can tell, it's an Avcom AC 200 PNR. Pretty much unused, works actually pretty nicely. I'm thinking $50. Nice PAX headset. Or all three, $500. And I'll pay for shipping.
