    JACK ADAPTERS

    adapters with wire are comfortable, but add some resistivity and their quality depends of wire quality (together with plugs and solders quality).

    short adapters (minimal or no wire) offer less resistance and you only depend of plugs and solders quality. in the other hand, they stress 3.5mm sockets harder. guess angled adapters will mitigate some of that stress compared to straight ones.

    most adapters are 2.5mm TRRS balanced female to 3.5mm TRS male, but there also some 2.5mm balanced to 4.4mm balanced.

    DC resistivity measurements (L+,R+,L-,R-, in mΩ):

    the 2.5mm socket is like those used into sources' cases, so expect longer durability (time will tell).
    but conductivity is very poor (the worst by far). the culprit is the flexible gold plated ribbon/pcb used to connect the contacts (thin and not great material probably). the resistance is the same as some 1.2m cables (+plugs), go figure.

    eagle 4.4mm female socket is not the usual cheap chinese socket. it is built for many insertions.
    3.5mm TRS male and 2.5mm TRRS male versions available as default options.

    couldn't measure ground to R- resistance, because the contact is very deep into the socket.
    you'll have to push 2.5mm jack all way long to get sound at right side.

    i don't like much the plugs. 4.4mm female socket looks cheap.

    I think Your synapsis-nerves are made from different selection of cables! :D

    Congrats... for ur own thread...

    what are the basic rules to post here?

    thanks.

    just created this thread because some people suggested that the measurements info should be found easier, rather than buried in posts from different threads.
    updating the info is also easier for me this way.

    we can keep discussing in the cables thread, or KZ thread in the case of cables for KZs.
    so i don't know about basic rules.. guess there are not rules, other than usual head-fi rules for threads.

    Noted...
    I was thinking it will be redundant with the previous / other thread.
    And I agree that u need ur own thread for ur hardwork...
    Keep the good jobs...
    I don't want to derail anymore..

    i didn't feel any need to "have my own thread" (this is my first thread). only wanted to put all my measurements together. first tried creating articles, which looked nice because of less limitation of pics/files, but this was not practical because i think that every update has to be approved by moderators and i'm making updates frequently.
    at last, opted for a new thread, where i could reserve posts to keep all the info together.

    edit: i insist, this thread can be useful to find and check many cables resistance measurements. that's all.
    the thread where we are discussing the cables is already @Dsnuts one (and KZs thread for KZ cables), so the threads are not redundant. this one is for checking measurements, cables threads for discussing.
