Does someone knows these plugs from CEMA Audio:

I have used CEMA jacks, connectors and splitters and they are great. The landing zones for soldering are nice and wide, especially the 4.4mm. You could ask the vendor to take a picture of the inside of the 2.5mm plug for reference. One thing though - they do not have a cinch inside to hold the cable. You will need to use heat shrink.

Thanks for the info. That sounds good!
Do you know where to get a 6.35mm plug marching regarding design and quality?

I don't I'm afraid. Ask the guy @CEMA, he might have one?

Just bought some litz occ copper wire from cosmic cables for 0.90p a metre, bargain, wasn't on the site but I asked and he said he had this that was going in the clearance section, I'll let you know what it's like when it arrives, in case anyone is interested.

What gauge?

 

[pardonpardon]

I contacted Ian right after I read your post, and he told everything was sold out unfortunately. Would have loved to get my hands on 10 meters of those. Did you buy it all? What gauge where these?

 

[chezzer]

24 AWG, no, I bought 16 metres

Does anyone know where to source good/premium quality jacks and MMCX/2PINS internals without the housing? Pic related.
Of course there is a bunch of these on AliExpress. But perhaps there are some with a better quality out there?

I've had a feeble attempt at searching this 657 page thread but I'm having no luck. Can somebody explain to me Sony's 3.5mm trrs connectors they have on full sized cans like 1AM2? There seems to be both single-ended and balanced cables for those headphones that seems to plug into the same 3.5mm socket and got a bit curious. Is it 'backwards compatible' with single-ended trs to trs cable (as in a regular aux cable)? If it is, I'm toying with the idea of modding my K712 to fit the 3.5mm trrs plug as it appears to be the most convenient and versatile solution for a detachable cable. Any thoughts?

Besides, that, what are people here's preferred balanced connectors for attaching cables to headphones?

Thanks in advance,
Nol

Do a continuity test on your stock cable and then make your cable the same way

I don't own the 1AM2, just the K712, unfortunately so not possible. Hence asking here.

Just measured it, I will modify my Beyerdynamic DT-770 Pro the same way. I only need one cable.
Sony MDR-1A and 1AM2 cable pinout from input 3.5mm to output 4.4mm and output 3.5mm;
T R R S /// T R R R S /// T R S
L+ R+ R- L- /// L+ L- R+ R- E /// L+ R+ (L-R-)

Ah. So if you plug a regular TRS into Sony's TRRS, both L- and R- from TRRS should be in contact with the Stem of the TRS? If so, Sony's 3.5mm TRRS seems 'backwads compatible' with the regular single ended stereo jack. Correct?

Yes, even if you take a cable with single ended connections on both sides it stil works.
