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.

You need to ne VERY careful of what you accuse someone of, you slimey little brain-damaged maggot, otherwise you might find yourself ending up in a court of law (yet again).

rubber covering,

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.

rubber covering,

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.

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.

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 wire.

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!

It's nice to know that you mucking around with CB radios all these years has not gone completely to waste.

You never know when to give up, do you? Litz wire is unlikely to be used in CB radio.
