Oh and wualta the pads got mailed this morning.
There is no rush on my end. I'm toying with a few designs and if I land on a good one I might even build some stators and try and see how good a DIY electrostat can really be.

Yes. It's a little sticky, and you should wear old clothes, but it's permanently flexible nature and ability to bond to anything should make it a good choice.

I just got a pair of HP-2s in immaculate condition, except they smell like they were used for an ashtray. I think I'm going to have to air them out for a week before really listening to them. I plugged them into my portable amp at work just to make sure they work, and while they made sound out of both drivers, the XM4 can't really drive them.

Good luck with the stench.

What i usually do in those situations is take apart the whole headphone as far as it can go, spray everything with Formula 409 or similar household cleanser, and let 'em soak for an hour or so.

The headband is washable but don't put it in a machine.

The earpads will probably lose some of their vinyl coating if you machine wash them, too, so, i dunno what to tell you to do about those.

I bet YOU are brave enough to open these up and tell us if they have the same foam as my YH-2.

I'm definitely planning on opening them up. Probably one night this week or next weekend. Right now, I don't want to put them in my backpack to take them home. I'm surprised how small they are. The close up pictures here make them look big They're also very comfortable.

Yeah, they're essentially comfortable but i have a big head and big ears, and i find something about the way the earpads sit on my ears to be pretty uncomfortable.

Of course, my YH-2 pads were very badly worn, and the sony pleather pads are only half a solution.

The pads on these could pass for new. They're still springy and only have one little nick in them.

Cigarette smoke, eh?

It's an aromatic oil, so anything you have that acts as a degreaser will do the job on the hard plastic bits, and you could probably even dunk the drivers in a dilute waterbased solvent/detergent (say, a d-limonene / 2-butoxyethanol cocktail (with some ammonia water for added kick) for a quick swish without damage, but the trickiest would be the earpads with their foam insides. Maybe a quick soak'n'squeeze in some plain ammonia water, a quick rinse and a squeeze-out between two layers of towels.

Glad to have you on Team Small Ortho, at any rate. Buddy up with ericj and see which mods work best.

Does anyone have an HP-50A?

Does anyone have an HP/YH-3?

Anyone have both of the above?

If you have a fire and flood restoration place near to you (servicemaster), you can ask them to put them in their Ozone machine. Usually if they have a load of smoke damaged things to add it to they don't charge much. It works very well without the worry of any liquid.

the question is will that much ozone do harm to the diaphragm? I supposed the diaphragm is PET film, ozone might make it brittle...

Bah, splitters!

I keep thinking i'd pay almost $25 for an HP-3 or HP-50(a,s,whatever) - but somehow it never really ends up happening.

I just keep seeing that guy in eastern europe trying to start his auction at $100usd. I'm sure he's just hoping the market will be ripe some day.

It'd be nice to think some manufacturers are keeping their eyes on those prices as well.

I guess I'll join the club; I have a pair of HP-3's.

I just found this site while searching for a replacement phones for my iPod. While getting hooked on reviews for MDR-V6, K81DJ, and FX-33, mods etc. I decided to dig out an old pair of headphones I bought when I was 17 (I'm 45 now). I did a search which lead me here... it seems I have a little treasure.

The pads are in rough shape and there is an intermittent connection in the cable. Other than that they look and sound fine. Any thoughts on the best way to spruce these up?

I have a 20 year old Harmon Kardon receiver that seems to drive these fine however I typically listen to my iPod these days. In reading through the thread it sounds like the iPod will not be able to drive these? Is there any way to get them to work with an iPod?
