Happy Birthday!

Oh, I'm sorry. I didn't know that they're hybrid headphones. I'm not sure how to make them sing together now.

I have no idea. But, I think you can convert them into electrostatic.

I like 3 microns Mylar, but anything from 1 to 3 microns should sound wonderful. You'll have to give them a few trials and errors on diaphragm tension before you are happy with the sound though. By the way, those drivers look nice. What is the inner diameter of the spacer holding the diaphragm?

Electret drivers use different diaphragm from electrostatic. Coating them with what you use on electrostaic won't help.

Beautiful!

Wow!

Nice work!!!

If blowing compressed air solved the problem, I'm afraid that the dust cover could have already been broken.

Yea, the dust cover is too fragile to withstand compressed air.

Very nice!

Nice!

Yea, their cable looks pretty nice.

What I really don't like on the KS headphone is its opening area at the back that is too little. It might just sound better if they completely take out the back perforated aluminum cover.

Nice!!!

Very nice!

Good idea!

Nice!

Wow! What woods are those black ones?

Thank you sir!

Nice going.

When I look at the back cover of 4070 the first thing that comes to mind is the cover of a butter plate.

Wow! That looks so much better than mine. Plexiglass can't stand the heat from solder gun, I think. I use bakelite though. Teflon is nice, but will it grip to the pins well?

I stretch a larger piece of Mylar that is enough for making a pair at one time, and they seem to match one and the other well. And yes, I still do the sound checking by knocking them against the table.

Is there any opening at all at the back? The damping material looks to be quite thick.
