Heat shrink them from the outside. It’s the only way to secure them properly.

You should be able to get ground from the 4.4mm sleeve, unless it's not connected. In some cases you need to get ground from a 3.5mm socket.

Need them to connect ground to both files then?

Problem with 4.4mm is that often the don’t have sleeve internally…

Not really. The end screw cap gives adequate secure tight fit if enough internal heatshrink is used.
The clear heatshrink on the outside is'nt absolutely necessary and is there only to prevent the wire chafing against the connector.

First time hooking up some LEMO connectors for a client's Focal Utopia.
Usually used in the medical industry they're probably about as tricky as Sennheiser HD800 to terminate and make secure.
Came out good but I feel like the older I get the shakier my hands get, lol.
Happy client.

Very nice! I worked in medical equipment repair for 33 years and replacing Lemo connectors was a very laborious task. Great connectors, but agreed, as difficult as the HD800 ones to get a clean, stable connection.

And I also fully agree with the shaky hands... I have to get my roommate to do some of my soldering because of it. Maybe time to see if 'bionic' hands have progressed to a usable state!

I would try using the 4.4mm sleeve. Ideally you want ground to be connected on both ends and on both channels. If the device you are using doesn't have the 4.4mm sleeve connected to ground (some DAPs are like that), you need to get ground from somewhere else, usually people get ground from a 3.5mm socket given that it should be grounded.

Is there US supplier that sells 2.5/4.4/Senn connectors at reasonable prices? I really don't want to go through Ali unless I have to.

Has anyone figured out what type of connectors IPX/T2 from estron/linum are? By which I mean industry standard name, (like MMCX) - or are they sui generis estron/linum product? Lunashops and Plussound have connectors but would be useful to know generic part type (if it has one).

Searching for IPX and T2 hasn't gotten me very far- perusing digikey/mouser etc... not much luck- closest I have seen is SSMB I think, but those don't have an o-ring and the detent ring looks a bit lower.

Did find this handy website in the process though https://connectorbook.com/identification.html?m=NNK&n=classes

Hello,
I'm looking for a quality 3.5 trs connector for a hifiman. It needs to be slim like the pic.
I found a couple on ebay but they look cheap. Thank you!

edit: I found these, but not sure they will fit?: https://www.redco.com/Redco-Male-3.5MM-Mini-TRS-Solder-Connector-Low-Profile.html

why does it need to be thin? HifiMan doesn't have recessed plugs...

oh really? I don't have them yet, and read that some cables don't fit. I think some have a recessed, manufacture issue. Prob ok...Thank you

No worries

Some of the older style round HFM is recessed. Anything less than 8mm will clear it.

Edit: Looking at your connectors on your link, both should work. As long as there is extra extension after the sleeve, it shouldn't matter what the shell size is.

Thank you. Getting frustrated because I ordered cables at a place and wasn't happy with the shipping. I just bought it and tried to forget it. Now I'm back there looking at connectors with $10 shipping. I was trying to save money, but as usual I am losing. THEN later I read about hart cables after digging digging digging for a reasonable custom cable. Now I can't avoid hearing about them or being recommended. Sorry, frustrated. I might just order the stupid thing after all and have the parts for an extra.

Hart cables are pretty popular(for a good reason too). I keep missing them on 2nd hand market at great prices. I ordered some connectors from Ali and decided to "mimic" hart cables. If you can bare the wait, Ali has pretty good selection and prices. Plus you will have your own diy custom cables perhaps cheaper.
