Trying to figure out if these are worth anything. There's two D C models, H30-10 and H10-13.4
There's and older Flightcom that doesn't appear to have a model number on it. The only number I can find on the Bose is AHX-32-01 located on the controller. Any information on any of these is appreciated, thanks.

13.4's are always worth something. One of my students just paid $100 for a used set of 13.4's of similar vintage/condition as yours.

edit: Didn't even see the bose. It's also worth maybe $300 from what I've seen. I think you'd do well posting these on the Denver craigslist under aviation. I tell my students to look there for used headsets locally.

Yes I can get about $150 US for a good condition 13.4.
The older Bose A series are worth at least $250-$300 depending on condition.

The Flightcom is a David Clark clone, they sold for about $90.00 new last time I checked. Other than price and color it is the same as the DC 10-30.

Everyone so far has interpreted your question of "worth anything" as having dollar signs attached, so I'll take the direction, are they worth having, as in "are they usable".

The early Bose headsets were more fragile than the newer ones--electronics being what they are, I wouldn't invest in an old Bose myself. If they work, they work well, but I wouldn't count on them to continue working. Bose will not repair any of the early versions.

Earlier David Clarks, however, are very robust. They're not ANR, of course, but they're solid. The 10-30 is the next version of the original 10-40--and I still have my 10-40, purchased new in 1978. The 10-13.4 is lighter, and came out a few years after the 10-30. Both are still being made, and both are top notch passive headsets. Both can be made much more comfortable with Oregon Aero comfort items, and the Oregon Aero "hushkit" can make them almost equal to ANR in listening capability. "Almost", but not quite, so a great upgrade is a Headsets Inc. ANR conversion, which I have done to one of my 10-13.4 headsets. DC will still repair any of their passive sets, not so sure about some of their earlier "experiments" into ANR. Their newer ANR sets (One-X and Pro-X) are outstanding headsets, and they service them well.

I'd hesitate to call the Flightcom a DC clone--looks a lot like it, but it's nowhere near the quality, and not nearly as solid. Personal experience has been that for occasional use, it's not a bad headset, but frequent use and it will fail, becoming scratchy and hard to hear, and the mic will become problematic, or likely the headset will just come apart. I bought a couple of them, one a child-size, for backseat use, and they're still in good shape, but I don't think they've been used more than a dozen times total in the last half dozen years. I've never heard of anyone attempting to get one fixed--they're essentially a throw away item.
