Don't know if this is standard or not, but it lists both methods.

Nice find! Thanks!

Sure thing.  It's a bit of a bummer that I put my XLR together off-standard, but at least I figured it out now before I started working on another cable for them...

I strip off the rubberized outer coating and copper wire shielding on the Mogami that I work with, so I put 2 wires to Ground and 1 each to the L/R signal.  Your way would work, but it's much easier to sleeve and to fit into the connector housings if you strip off the shielding.

THANKS.

Why are you guys doing unbalanced xlr cables? If you're planning on doing a detachable mod, why don't you use a 4 pin xlr in case you ever decide to go balanced.
Now, if you're building a cable for an akg heaphone (they are the only ones that come to mind when thinking about unbalanced xlr connections) just follow whatever standard they have.

In any case, remember that your shield should only connect at the source end of your cable, whether that is the 3-pin xlr or TRS plug.

What I would do for either case is:
1 wire to right side.
1 wire to left side.
2 wires to ground.
Shield to ground on source side.

My DT880 is wired the same as the LCD's cable and terminates to TRS as I don't have a balanced amp right now. If I ever do get an amp its just a matter of unsoldering the TRS and connecting a 4 pin XLR.

Yeah, that's the same way I would do it if I were to do a detachable mod with mini XLRs. I think liquidzoo and i luvmusic 2 were talking about a TRS to 3 pin XLR cable which only makes sense for AKG headphones.

 

I do all my personal detachable mods with Lemo plugs because of the extremely small profile (I would never even think about drilling my headphones) and I can use the same cable on all of my headphones (D2000, DT770 and HE-400)

MMCX connectors, you can get them cheap on ebay and other online retailers.

hi you said you used  detachable mods with Lemo plugs could you please tell me what are the model number for both plug and socket and if you can upload the picture of your moded headphone so i can have an idea what they look like when installed.thank you.

one more thing the mini xlr mod that i did with DT770 it's not that easy to do there is few things you need to watchout for. size of hole for the xlr socket,how much space you have inside the cup for height and lenght of the socket you can't pass the height of that existing hole on the cup if you pass that the driver will not seat properly and the lenght of the socket it will hit the side of the driver.i still have the DT880 that i would like to mod so please if you can provide me with more info regarding headphone mod please do so again thank you.

Sorry to hear that... :( It's always wisest to start your modding journey on a pair (or two, or three) of inexpensive headphones, so you get your skills honed up to the task. Replacement drivers are usually available but you'll have to decide if it's worth purchasing them and doing any further mods yourself, or perhaps hiring out a local electronics tech to assist you with the task.

 

If you do seek the assistance of another hobbyist or electronics tech, I highly recommend looking for someone local and trying to get references before you deal with them. I'm lucky enough to have been working in the electronics industry for over 30 years, so I've never needed help for my personal stuff. I totally sympathize with you and others who have a mod go bad, but it's even worse if you then turn to others for help and they turn out to be just as bad. Thankfully those 'horror stories' are few and far between.

 

Good luck whichever way you go...

 

Dale
