Hi folks,
I've been thinking about doing this sort of modification to my M50s - the 11.5ft straight cable is a real hassle while walking down the street - I can't find anywhere to put it. A removable cable would mean I could switch between longer cables for use with my amp at home and shorter cables while out and about with them.
I was reading a different thread and saw the following photo, which was posted by racer_x124
here.
So as you can see here, he's used a 3-pin mini-XLR jack instead of the Lumberg or another 3.5mm TRS chassis. I like this idea a lot more for a couple of reasons. First, the cable locks in, so there's less chance of pulling it out by mistake. But more importantly, the panel mount jack for a mini-XLR seems to be a lot smaller on the inside than most of the 3.5mm ones I've seen used in this thread. The question I have is whether or not there would be enough room to mount the jack and connect the driver to it without disturbing the internal structure - i.e. without clipping or filing the plastic ring as is necessary for most of these 3.5mm mods. The connector I was looking at possibly using is a
Switchcraft TB3MB, which is a standard 3-pin mini-XLR jack with a mounting nut. The B model is painted black, which should look nice with these cans. There is a detailed spec sheet for the connector
here.
The specs look to show a depth of about 0.488" maximum from the ring to the back of the module. I may need to open up my cans and do some measurements to see if there's enough wiggle room in there. But just looking at it it does seem like it takes up much less room on the inside than these TRS barrel jacks. racer_x124's post says that "I had a mini XLR in mine with no problems at all. There is a ton of room in the M50," so that sounds hopeful. I think I should PM him as well even though it doesn't look like he's posted in the last year.
If anyone has any advice or comments on this idea I'd love to hear them. I just want to do this safely and modify the internal parts of the headphones as little as possible.
