Don't try to splice earphone cables

    After weeks to get my sound isolated earphones, which cut out surrounding noise
    perfectly with a bit of music, I ordered an iPod shuffle, a hotel matchbox sized MP3 player.

    But to keep my address private I sent it to my old address which redirects to my PO BOX,
    I always do that for mail order and on the occasion a courier goes to my old address they
    soon work it out and I get them to send it to the PO BOX themselves.

    JB HIFI didn't do that, it says order complete and no IPOD... yada yada yada, so I cut
    the cables on the Blackberry earphones and the $90 Sound Insulating earphones, well
    worth the money!

    There's 5 wires! Blackberry uses a smal USB plug so I was trying to plug my SI earphones
    into the Blackberry. So I snip further up the cable where it splits into 2 and there's 2 wires
    but different colours to the 5 at the base of the cable. OK I'm going to have to hotwire the
    earphones and see what gives a signal. So I snip the $90 earphone cable and despite having
    stripped 1000 wires with my teeth with 100% record, this cable is made of weird rubber,
    and the wires aren't even copper or insulated, they're frayed wire in the same rubber covering,
    insulate by a powder coating it seems, I got one wire stripped but no luck. 2 earphones wrecked,
    now I have to buy a paper with good ole earplugs and hope I don't get verbally assaulted too badly.

    So I left out an "are" - what is your problem, loser? I blame the

    It must be embarrasing being you on Talk Like A Pirate Day! Arr..

    Not as embarrassing as being an incompetent fool who has just fucked up two
    pairs or earphones.

    Do you ever have something nice to say?

    Opening one of your posts is as predictable as opening a sewerage man hole.

    Yes, to those that are deserved.

    Not with the predatory abuse you constantly spout.

    Do you really want me to repost examples of your unwarranted and unprovoked
    verbal abuse or are you going to reconsider that comment?

    Anyone can snip quotes out of context and twist them, it takes a pair of real
    bogan drongoes to contantly spout abuse all day every day. Big brave pair
    of puppies you two are, brain dead keyboard warriors.

    And what qualifications do you have that makes you think you have a right to
    abuse people and post utter nonsense to multiple groups?

    I would rather be a "bogan" (though I'm not) then a convicted mentally ill
    criminal nutjob stalker with a messiah complex like you are.

    I think they're made that way so as to obviate the standard solution of
    replacing the plug when the wearer makes the the all too common mistake
    of trying to walk away from the device the headphones are plugged into,
    causing the conductors to part company (if only internally) with the plug.

    They're probably made with specially designed inadequate strain relief
    as well.

    I've had some success by just pretending I haven't noticed, and
    soldering a wire onto them regardless.

    Actually the stretchy sheath and frayed wire on the $90 earphones is a lot easier to bend than the blackberry cable.

    Any candidates for a stretchy conducting material to solve the sudden jolt problem?

    I'll have a go cutting the sheath lengthwise with scissors, but working with sub millimeter wires is a pain.

  15. Sylvia Else

    Probably not in the cases where I've had success.

    I think there are variants where there are some real metal strands in
    there, together with many non-metal fibres.

  16. Clocky

    Clocky Guest

    Correct. The non-copper strands are what provide the strength , but they can
    usually burnt away with a lighter or match to make it easier to solder the

    It's called Litz wire. Gives it strength and flexibility.

    Found this very effective BUT slow.................
    A Dremel tool with a stainless steel wire wheel attachment works very well.
    I found that the stainless wheel works faster and lasts longer than the
    carbon steel wheel, with the added advantage that the small pieces of the
    wheel brush that wear off during the process are non-magnetic, so they won't
    attach to nearby driver magnets (don't need little pieces of wire inside my
    EMIMs and EMITs!). Simply remove ~ 1/2" of the insulation, then untwist the
    various strands from each other (the Cardas Litz has 3 counterwound layers
    of different diameter wire to untwist, do them one at a time) and flatten
    them into a flat fan shape. Set the Dremel to about 1/2 of maximum speed and
    apply to the coated wire, ensuring that the wheel is ALWAYS turning toward
    the ends of the wire (otherwise they will entangle with the spinning wire
    wheel and snap off!). 10 seconds on each side of the fanned wire is very
    effective at removing the varnish coating without destroying the wires. Then
    re-fan the wire in a different direction and repeat the process 2 or 3 times
    to ensure that all the wires get stripped. You will be left with nice clean
    varnish-free wires, which can then be tinned as usual.

    As a test of this method I measured the AC impedance of each of the wires of
    the same length at 10kHz using my LCR meter, and found that they all were
    very consistent, indicating that I was effectively and consistently removing
    the varnish and using all the wires in the bundle.

    By the way, the speakers sound terrific! I'm not sure how much of the
    improvement was from the litz wire, but it certainly didn't hurt the sound!

    What you *saw* on the photo was correct, and I agreed with that. What
    you imagined after that was not agreed and you yourself stated you
    could not see inside the 'van, so everything else is supposition on
    your part. Indeed much of it was just downright fabrication or
    misrepresentation of the few facts you held. I even fed you false
    details and you dutifully rehashed them and re-presented them as
    facts, like a Murdoch journalist.

    I'm surprised you want to go on with this story. Watching it unfold
    last time was fascinating and like watching a train wreck in slow
    motion. I found it difficult to believe you had no humility and felt
    no embarrassment with regard to your behavior. It was only because you
    wrote the 'help me Obi Wan Sylvia, you're my only friend' message a
    couple of days later that I cut you some slack. Up to that point I was
    compiling a file for the Police.

    I had already been in contact with my local council and confirmed that
    there had been no FOI requests regarding my property (your claims were
    therefore bullshit) , and I had visited the local police and enquired
    about applying for a warrant charging you with stalking. Once I read
    you email to Sylvia I understood your frame of mind at that time I
    ceased all action. You came very close indeed.


    You don't have a sufficient case to get a stalking charge made,
    you need to show each of the 4 conditions to qualify that stalking occured.

    1/ The alleged stalker caused you feelings of apprehension - Oh Dear! *tick*
    2/ The alleged stalker communicated with you - GASP! *tick*
    3/ The alleged stalking occured on more than one occasion! Persistent Bastard! *tick*
    4/ You've got a good rack! *cross*

    Each of these stringent criteria must be met! Otherwise the police receptionist won't
    give you a tour of all the bonus options like a free week lock up at the watch house, just sign here!
