If the diaphragm sticks to one side of the two stators, the tension might not have been enough. You can use a hair blower and try to heat shrink the diaphragms a little bit. Also, it might help if you can paint the copper side of the stator. I painted mine with 3 layers of plastic paint, and it worked fine.

You are almost there. Please try.

Thanks Wachara, I will try both of those things when I open them back up. I did find that the earpads for Koss ESP950 headphones work quite well on these with a little modification of the housing. I will take pictures and post them.

Hi Matt,

Please try again. You are almost there. Please don't give up.

About the earpads, where do you buy them from? How do they fit after the modification?

May I ask what amplifiers the folks here are using? I'm increasingly tempted to try building a pair of these, but most amp designs require a substantial investment.

Hi Spasticteapot,

Please check earlier posts. There are a few circuits that you can try.

I think I need to start looking around for an appropriate set of step-up xformers.

Has anyone compared these to commercial electrostatic offerings?

I don't quite understand your question. Do you mean how the sound from DIY headphones compares to those commercial ones?

Hi everyone.

Been reading this thread with interest and am thinking of giving some headphones a go.

I was looking for a source of mylar in the uk and i found these guys
Sams Models : : Catalogue Section B : :

Just over half way donw they do .00025", is that suitable?

I also noticed they do metalized. Do you think this could be used and would it remove the need for coating?

Thanks.

Yup.

Has anyone done any measurements?

Hi Graeme UK,

I think the .00025" Mylar is suitable. It should be equivalent to 6 micron Mylar. I have tried it, and I liked it.

I'm not sure about the metalized diaphragm. However, you need to make the diaphragm to very slightly conductive. With metalized diaphragm, I'm not sure if it will be too conductive though. High resistance value on diaphragm surface is good.
