My left ear piece is not working, i want to repair it

This is a very common problem with wired headphones!
The wires associated are too delicate to resist pressure or tug of any kind.
I would suggest you to get a replacement as its often not easy to repair em yourself.
Even then if you want to give it a shot read below:
But before you read any further do remember to check the headphones on other appliances as it might be the case that they are being supported in one you trying since long! If already done read further!
1. Open the left earpiece, in most off the headphones there are little 'voids' through which you can easily slide in any sharp object and open them.
2. You would be lucky if you can see the wire detached from the back of the speaker. You just need to attach it. For temporary measure you may use tape whereas you need to solder it for a permanent cure!
3. Now, if you see no breach then its alarming as the wire may have detached anywhere through the length. You either need to replace the entire wire or get a new headphone in that case!

Jbl roxy over ear headphones ref 430 need to install new cord. how do i open cans?

Headphone speakers stop functioning properly when the wireconnections to the speaker are broken. This problem often develops when theheadphone cord gets jerked while being worn. The solder connection might alsodetach over time if it was not properly manufactured. The wire can bereconnected to the speaker with a soldering iron to repair the headphone. Beaware, though, that headphones are not designed to be user maintained in thisfashion. In some cases, it is difficult to get to the speaker due to the casingdesign.
Instructions and tools needed
Screwdriver or butter knife (depending on headphone design),Soldering iron, Electrical solder
1 Plug in the solderingiron. It takes a few minutes for it to get warm enough to be used.
2 Unscrew the screws holdingthe headphone casing over the speakers. This step applies only to models thatuse screws in the casing.
3 Insert the end of the butterknife into the seam on the headphone ear pieces. Pry the two halves of thecasing apart. This step is performed only on headphone models that do not usescrews in the casing.
4 Touch the tip of thesoldering iron to the electrical solder. A small drop should melt onto the tipof the iron.
5 Touch the tip of the soldering iron to the end of thedetached speaker wire inside the headphone speaker cavity. Try to get an evencoating of solder around the exposed metal end of the wire. The soldersolidifies on the wire once the soldering iron is removed.
6 Touch the end of the wire tothe solder on the metal tab attached to the speaker.
7 Touch the tip of the solderingiron to where the wire and tab connect. The heat of the soldering iron meltsthe solder on the wire and tab together. This repairs the broken connectionbetween the wire and speaker.
8 Replace the speaker casingonto the headphone. It should snap back into place for models without screws Thanks.

Cat chewed through right speaker wire that supplies right speaker...tried sawdering wires together...still no there a special way to connect these??? thanks

Look carefully over the entire length of the wire for any puncture or crushed insulation. Cat teeth, especially kitten teeth, can exert needle-like pressure that could sever the wire without leaving easily visible damage. My rock-headed cat does this too.

Almost universally, a red or green colored wire is (+) and a copper colored wire is the ground (-). Make sure the same colored wires are soldered together.

The best way to repair headphone wires is to offset the solder joints of the (+) wire and the ground wire so that they don't short circuit. Inotherwords, don't have the solder joints opposite of each other so that they might touch together.

A good quality shrink tubing should go over the repair to relieve stress on the soldered joints. These wires, by the way, are enamel-coated and need to be tinned with resin-core electronic solder before joining and soldering the wires together.

Don't breathe the fumes when soldering and wash your hands after you are done handling the solder.

Right channel is busted. Can't hear a thing though the left channel plays alright.

99 times out of 100 it's a faulty cable/connection. Could be anywhere along the length, from connector to the headphone itself. If you're handy with a soldering iron, it's usually easily fixed.

My technics headphones have just stopped working, is it probably a faulty chord?

Unusual to fail on both channels at the same time, however the most common cause is a break in the wire just above the 3.5mm plug.
I hope I have been of help but please do not hesitate to ask if you have any further questions.
I appreciate your vote if you appreciate my reply.

The right earphone stopped working. If I twist the wire it works sometimes, what is the problem and how can I fix it?

The wire is interrupted somewhere inside,twist the wire along it`s length and find where is the problem.Cut it and get it back together. Or if not,buy some new ones.These are the two ways

Cord broke off at plug connection point Does Bose repair this? Does anyone repair this?

it certainly could be repaired. just requires a new connector and some soldering expertise. unsure of any 'store' or 'vendor' that one could walk into for such a repair. depening on how much they cost it may or may not be worth pursuing repair from the manufacturer. perhaps you have a friend who can solder? then you may be able to get the connector at a store such as radio shack.

alternative - it wont be pretty, but if you have a compatible connector from some other unused or broken headphones or cable - you could cut off that connector (keeping some length of wire to work with)
-separate the 2 wires (both from the new connector and from the headphones) and strip back the the insulation on them, about 1" or so.
-unwrap the shield and twist it to keep the stands together
-this should reveal another insulated wire - strip this one back about 0.5"
-join the matching wires from the 2 parts (4 total connections) take care to arrange the wires so that none of the bare wire parts touch each other - use tape (preferably electrical tape) to cover them individually to achieve this.
-test it out.

One wire is taller than the other and i cant make them both the same cause it looks like it might break?

This is normal. The company designs them so that the cord hangs down one side to your music player/radio, etc. If you look at the headphones, there is an "L" and an "R" on each earpiece, put them in the correct ear and you've got them on correctly for proper stereo sound.

Again, the reason one cord is longer than the other is to allow for the cord to hang down one side to your player. Sony and many other 3rd party earphone makers also have similar designs, while there are some that still use the center cord and equal length ear piece cords.

Hpoe you found this very helpful, and best regards!

Jack replacement for mdr-v500 headphone

You don't need to look inside the plug... just open up the earcups and test the jack plug with a continuity tester.

But FYI, Red = ring, Green = tip.
