    the 2.5mm TRRS balun will be a great help in your case, to distinguish the cores.

    ifi nano black uses 3.5mm TRS/TRRS sockets. due to this dual option, the pins are probably L+, R+, L-, R- (TRRS).
    your 2.5mm TRRS socket is probably R-, R+, R-, L- (TRRS), most standard type.
    balun 2.5mm TRRS is labeled L,R,V,Gnd (TRRS).

    to identify the signals carried by each wire, plug the balun into the 2.5mm TRRS socket of your adapter. with the multimeter, one lead into a balun contact, the other touching a wire:
    balun V label is ring2, so L+ signal. locate the 2 matching wires. they have to be soldered to tip of 3.5mm TRRS plug, which is the last tiny contact, far from the jack (L+).
    balun R label is ring1, so R+ signal. locate the 2 matching wires. they have to be soldered to ring1 of 3.5mm TRRS plug, which is the middle contact (R+).
    balun Gnd label is sleeve, so L- signal. locate the 2 matching wires. they have to be soldered to ring2 of 3.5mm TRRS plug, which is the first contact, nearest to the jack (L-).
    balun L label is tip, so R- signal. locate the 2 matching wires. they have to be soldered to sleeve of 3.5mm TRRS plug (R-).

    Does anyone have an ebay source for Sennheiser HD600 connectors? There was a white pair posted a while back, but those appear to be out of stock. There are a lot but not sure of quality. Not sure I want to buy the sennheiser cable and steal those plugs. If I do go that route, would you leave a strand of wire soldered and connect it to the new cable, or would complete desoldering be required?

    @imas69 sorry i've been meaning to thank you for a while for putting me on to cosmic. I've bought quite a bit of neotech cable and various connectors from them and Ian has been fantastic, first off they're cheaper which is always good and the postage is always super quick but the customer service in terms of advice on build techniques and products is 2nd to none, so thanks again and i can highly recommend them to anyone else how needs DIY bits in UK and europe :)

    i dont want to do Cosmic out of any business, but if you're in the US, have you tried Norne, Double helix of plussound? they all sell connectors at about the same price :)

    Hi all, I want to mod my TH X00 using SMC 2963 connector as pictured below.

    I want to know if there are adapters readily available to convert this to a 3.5mm female so I can use with some of my existing cables? Or if there is a guide on how to create a short adapter/cable myself?

    @teknorob23, not a problem at all, I have used them a few times and found the service to be great, which is why I plug them when I get a chance, I hadn't seen that you were in the USA noverbeck, apologies, if I were you I would
    go to Trevor at Norne audio and steer well clear of double helix.
