How-to ATH-AD900x Detachable Cable Mod (ATH-ADXXXx) (and what NOT to do)

    The socket would be too large, unless you find one with a diameter of 8mm (which would be surprising) which is the max width for a socket to be installed. So as an other comment pointed it out, you can always do a "piggy-tail" mod to use the headphones with a mini-xlr.

    Are you talking about the existing hole? I was thinking it would not fit. But, If I made the hole larger would be too large inside the cup?

    No about the max width you can create, because anything larger would go through the entire width of the plastic ring.

    Thank you for your instructions!

    I did the mod yesterday and have some problems now which I can't really associate with anything.

    After the mod I made some Stereotests with the following findings:

    - Sound on Central -> Sound on Central
    - Sound on Left -> Sound same as for Central
    - Sound on Right -> Lower Volume sound but just on the right

    Can maybe someone pinpoint my problem?

    Is that a regular 3.5 mm RCA?
    I find them unreliable .
    I have seen mini gold coax screw-ons that is where I am headed.
    Well I use kimber TC4 too so I need rugged

    I had a similar issue when i did this mod to my HD500X. It was caused by the left and right channels being wired up backwards, but it can also be caused if there is a bridge of solder between the wires or if the wires are touching. Hope this helps.
