When I've had time recently I've assembled a few more DIY electrostatic headphones:
First off, the last of the Superex chassis I had in stock so I designed a new stator design for them:
This has been a long running project to to make drivers and test the various aspects in a controlled housing. They are not ideal as they are mostly closed but I got a bunch of them for next to nothing years ago. New stators with some minor tweaks and a protective grill too:
These are not really built for sound quality but to test different coatings, distortion tests on drivers and all that jive but still fun to have a pile of these here.
Since the Superex is just a Beyerdynamic clone, I found some DT880's with blown drivers that could also work:
The need to be modified internally a bit to open up the back but nothing major.
Different stators on this one and the drivers have to be at a 45° angle to get it all to fit (not that it matters at all) but same basic idea as above
Round them off with some nice leather pads, silicone 6 core cable and my new Stax plugs that I've been refining recently. These do sound better than the Superex shell as the backwave is more open.
Finally, the second of those Kiwi Ears headphones was fitted with drivers:
No major changes here except I didn't use the bayonet plate to fix the earpads, I rather slipped the stock pads over the lip of the housing which helped a lot
Also some simple tweaks to ensure better baffle seal:
Thick cloth tape here and it works nicely. These are okey sounding headphones for next to no money at all.
