I'd consider a pair, but I don't want to be renamed Locutus.

They're also unobtainium, so you probably wouldn't find a pair anyways. If you do though, let me know, I sort of have a thing for weird looking **** like this.
I thought the Yamaha YH-5M was the unobtanium.
Which reminds me, there are still a few unknowns hanging around out there I can feel it deep in my bones. Someone has to find one.
M_S 8730 perhaps?... I think maybe Kabeer was the last chap to find that Ca_ton ( not named for safety reasons in searches ) I know there is one not yet found for sure ( not saying because of confidentiality agreement ) GET SEARCHING!
Dyna-x mang Dyna-x ultimaunobtainium, though one person in here has one :)
Here's my re-cabled HP-50A. I used the stock wires from the Left cup to the Right cup.
Kapton Gold looks nice with these headphones.
I damped with the stock open cell foam and a disk of 4 mm dense, soft wool felt. Sounds great.
Thanks nick n!
No screws. Snap tabs hold the baffle to the cup.
Stock open cell foam damping. That's it.
Left channel on left; Right channel on right. Stock Mono wiring.
Re-cabled for stereo with navships (ebay seller) using 26 AWG
Kapton insulated SPC multi-stranded wire - 4 wires are braided.
Thick (4mm) dense, soft wool felt damping over stock open
cell foam on the inside. It was a tight fit with the felt and
The Kapton wire is microphonic so I'll be looking for a soft
Pads are in great shape. They're secured with double-sided
tape cut from a large sheet. The tape seals the access
openings for the snap tabs.
Edit: I removed the dense felt and tried the configuration I used with a set of HP-1's. The sound quality improved quite a bit over the dense felt, alone. The stock open cell foam was too much with this configuration, though, so I cut it down and the sound remained over-damped. I removed the open cell foam and like what I hear. Pictures "show and tell."
Ring of Paxmate
Thin cotton disc.
nick n's secret sauce overlays Paxmate disc and cotton disc.
Stock open cell foam over-damped the sound.
Trimmed open cell foam disc over-damped the sound so I did not use it.
The back wave vents through the sides of the damping stack and out the un-damped cup slots.
THANKS for that i will have to give it a shot, that cotton must bring up the highs a fair bit then? What cotton is it?
Hmm ... late night modding hey. I know it all too well.
just threw mine on again to try and noticed they need a boost in the highs for sure.
YHD-1 to Fostex T10 Transplant
This modification sounds real good.
Too much slack in slider clamps. 2 layers of closed cell craft
foam serves as a friction brake so the cup rails remain in place.
Rubber cement keeps the closed cell foam in place.
Too much slack at the slider rails hinge was taken up with 3 cm
of Scotch tape.
Speaker grille cloth secured with double sided tape.
28 gage steel baffle is strong and light-weight.
Closed cell foam gaskets on both side of steel baffle.
Double sided tape exposed for securing pads.
Closed cell foam ear side gaskets and steel baffles.
Bushings/spacers have been installed on hinge and slider mechanism.
Adapters to seal the large cable entry opening in the T10 for
the YHD-1 smaller cable and strain relief. This is made with
2-mm hard plastic with a layer of closed cell foam. Without
these, there would be huge holes at the cable entry that
would function like big bass ports = Boomy Bass Bloat.
These were super glued inside the cups and over the T10
T10 stock pads are in pretty good shape.
Yamaha YHD-1 and Fostex T10 components ready for
Closed cell foam gasket over rear of steel baffle.
Hot glue holds and seals YHD-1 driver to baffle.
T10 yellow biscuit over foam in cup.
3, T10 cup-to-baffle screws.
^Very nice mod! Great that it sounds nice to you too
Welp, there's a YH-1000 on ebay.com...
...but it's listed for $1899...
Stop. Stop posting links to or even talking about stuff that's in an active eBay listing. Its a gigantic middle finger to anyone who may be eyeballing the auction.
Absolute best way to approach that ebay listing aspect is to notify whoever you think might be interested or whoever you speak with a fair bit about things, using the private message system.
We aways have to remember that things ( ANYTHING ) posted out in the open are also read by a huge massive number of people that have not signed up here A.K.A. "Joe Lunchpail General Public", or anyone instantly searching the web about a listing or for info without bothering to contribute or do much , if any, work.. Not only that but it possibly definitely drives up prices from sellers . I have noticed more than a few times where I was late getting back to a real deal only to find they relisted it at a way higher price or that is close to the current ripoff prices.
It's also why I often obscure names and model numbers in posts.
Much goes on behind the scenes here .
Something to keep in mind for the future.
Everyone benefits this way, and as takato said it doesn't screw anyone out of a deal they managed to find that went under the radar for whatever reason. The adrenaline rush with some search results stuff is a real thing at least here :)
BMF: what happened to the stock T-10 drivers in the YHD transplant i forget. You know you are hardcore when you are using a rare shell with other rare drivers instead :)
You've been doing it repeatedly over the past few days with various headphones.
