It is hard to prices them since the history isn't known and we don't know how well they work.
The one pair is a DC 13.4. They are only $325 new.
The other pair I can't identify either.
If you want contact DC via the customer service link on their website and have both headsets refurbed by DC. They usually do this for little to no charge depending on what they find wrong. Then you can ask a bit more for them.
This was back when the DC aviation line consisted of the H-10-00, H-10-30, H-10-40, H-10-66 for RW, and the H-10-80; and prior to the 13.4 ever existing.
So they're basically a super bulky lookin 10-60? I have a 10-60 and it has all you mentioned except for the bulkiness and weight... I love DC headsetsYou guys serious? All you can't ID? Am I that old?
The other pair are H-10-80s. Not produced by DC anymore, but were top of the line at one time. I just recently had my pair refurb'd by DC, and they run like new; only headsets Ive ever had. Each earpiece has individual volume control. Only drawback to these is the weight, as they're kind of hefty. But still good. Mine were manufactured in 1990 and purchased new.

150 for the 10-13.4 sounds fair to me. I don't know about the 10-80, some might want it because it's out of production or because that's what they've always had and theirs broke, who knows! Some people get attached to models...Thanks for the info guys. I'm not sure if they where used 1000 hours or only 5 hours. I have a second hand store and there is no market here for them. I did have they tested and both are in wokring order. mics and speakers. I was asking 225 since there was a post that was asking that much. But selling both pair at 300.00 seems to be a fair price. Does 300 for both seem like a fair price to you guys?
