Does anyone know where i can find a 2.5mm TRRS male for my Sennheiser HD598?
It broke off..

Does the HD598 not have some locking mechanism? Found this a while ago: http://global.rakuten.com/en/store/audio-s/item/hpc35hd59825/ and wondered what was going on since I have also seen replacement cables that were trrs.

Weird! That link shows two TRS ends.
From all the stocks i've found via google images, all use TRRS.
Can't find a TRRS male 2.5mm let alone one small enough to fit the HD 598 socket hole.

A camera connector that somehow is now the standard for portable balanced amps
This is the matching plug for headphone cable: http://www.mouser.com/ProductDetail/Kobiconn/163-191J-E/?qs=sGAEpiMZZMv0W4pxf2HiVzeGJYwRlHzHtO53G2%2fcJfI%3d
It looks like an RSA Protector 4-Pin.

Having sortof same issues, i need to replace the cable for my HD598's, and the only way i have been able to even think of doing it is to solder it directly or making somenthing like mini xlr mod, although i can't find a space to fit mini xlr.......i reaaallly would prefer to solder it directly to the plug that goes to the standard 598 2,5mm hole.
How about this?

Yea. 
There's this option:
It's small enough for the hole most likely, but will need a 3.5mm paired with it.
Too many connecting connectors might lower conduction = lower sound quality.
Let me know if you find anything, i'm still looking as we speak.
How big is this opening? Would this one not work?
i highly doubt that neither will fit.....the plug goes quite deep into the hole. i think the diameter of the plug (not the connector the plastic bit) is around 1/4" (maybe bit more accurate around 6,20mm). and if the plug is thicker it wont fit 
You're right.
It fits the male plug along with the thread which is another 4mm or so, so it's pretty deep in the hole (no pin intended).
Hard to find another alternative.
Looks like we'll need the original connector w/ thread or mod it with another input socket.
