DIY Cable Questions and Comments Thread

[killaHz]

Anybody know of an MMCX Connector that has an actual strain relief? I havent found any, even the Eidolic ones are without. How do you guys make your DIY IEM Cables last?

I looked through the wire supply links in the original post, and it's almost all microphone cable, guitar cable, some hookup wire, etc.—nothing that really resembles the stuff that's in the name-brand cables. Is the only way to get OCC and/or litz wire like the pros to have it custom-made by the factory? I've seen some AliExpress entries that say that's what they're selling, but it's weirdly expensive even by the vaunted standards of audio wire, and I'm loath to purchase from people who don't know how to spell 'litz.'

i've bought some wires in this shop at AE successfully: https://www.aliexpress.com/store/5003206
true up-occ litz wires. sure they don't speak English, but the wires are legit.

other store where you can find nice litz cardas or neotech wires at good price is this: https://www.hificollective.co.uk/
they surely speak English..

Hello All, has anyone come across a cable tester similar to the one pictured here, which also tests 2.5mm trrs or even 4.4mm terminations. thx

If it had featured resistance, capacitance, and inductance measurements, it would be brilliant.
As it is, it looks very comfortable if you need to check lots of cables.

thanks for coming back to me and sorry my post was a bit unclear, as i'm not looking to buy this actual model, but i wanted to see if anyone has found a similar tester which also has 2.5mm or 4.4mm balanced jacks?

How do you fixiate the wire in the shell, so theres no strain on the soldered connection is what I meant, sorry beeing unclear

Oh. I think the most common thing is to pack the soldered joints with hot glue.

Dang, thats what im doing and im not really happy with that. Guess Ill check out some epoxys and dual component glues

Hello everyone,

This is a re-post of the thread I made, after which I found out that this one existed and opted to post in here instead (I've requested for that thread to be deleted).

First of all, I'm a complete newbie to soldering MMCX cables. Therefore, I have some questions regarding the soldering of a new MMCX male connector onto my cable.


1: As you can see, the cable has 2 wires. The grey wire branching to the left and the yellow one to the right. Is one of them hot and the other one cold?


2: How should I solder them onto the MMCX plugs, should I just solder the silver ground wire onto one of the outer pins and combine hot + cold and solder them onto the center pin? This is rather confusing to me

Thank you for your help

the silver wires on the outside are the shield. one of the wires is your signal, that one goes to the center pin, the other is ground, outside pin/shell

Thank you for your reply. So basically, I can just cut the shield away. Also, there is no way to know which one is the signal other than to solder and test? I don't have a multimeter.

arent the wires different colors? kinda hard to see in the picture

I have laid the wires bare, but it's still difficult to see. I think that the colors are very similar, if not the same. They both have a yellow tint, or it seems that way at least. Only the shielding cable is totally silver-colored. Btw, this is the official cable for GR07 detachable version. Cable link HERE.

...get a multimeter. Seriously. Doing any kind of electronics wiring without even a cheapie is asking for trouble. If only to check you haven’t shorted them out after soldering.

I'll be doing my cable/mmcx repair in the next few weeks. I have a mulitmeter but no idea what i need to do with it. How do i confirm which is the signal (mine are the same colour) wire etc and what should i check after soldering?
