Pictures of the connectors are here
The female panel mount mini XLR has too large of a diameter to work in the Beyer phones. There is a clearance issue between it and the driver plate. We can use the connectors in the link or we can use the same connectors used on the HiFiMan headphones. Those are the only 2 options that will work.
ok thanks. So what about my 2nd part of the question (detachable cable with stock, without buying a moonaudio cable?)
