I need to replace my headphone plug end

I have stripped my wires and found the two pair of wires one is red and gold and one is green and gold ... I understand that the gold wires are ground and the left and right are the green and red ... however I have a radioshack plug end with 3 terminals .. part number 274-0869 ... since this part comes without any specs or instructions I cannot determine which is the ground and what is the right or left ... please help.

Many have complained about a lack of instructions for the Radio Shack 1/8" rplacement plug. I recently had to fix my eMachines speakers after many years of use.

1. Remove the plastic protective housing from Radio Shack's part# 274-0869. It covers the screws used to connect your wires.

2. Cut the defective end off off your speakers or headphones to be repaired. Place the knurled gold housing and then the plastic prtective housing onto the wire of the device being repaired (to avoid doing things twice).

3. Strip about 1 inch of shield from the end of the cable being repaired.

4. You may wish to "tin" the braided wires with a soldering iron to ensure a quality repair with limited chance for "shorts."

5. On my speakers there were white, red and copper wires. The copper wire is the cable shield and connects to the longest connector. White connects to the center screw (the core of the plug), red connects to the 2nd shortest screw lead and the sheild (copper) wire connects to the longest (furthest from the tip of the plug).

I had pics but the size limitation by Fixya are unrealistic.... Good Luck!

I have to replace the plug on my headphones. I have stripped both wires and found that there are two wires on each side. Am I correct in assuming that the gold wires on each side are the ground wires and...

Yes that's correct! The Red will be right and Green left. You might have to scrape the wire ends with a Stanley Knife to get solder to stick. It's best to apply solder to the wires first. I find that a bit of spit helps to get the solder on to the wires.

My jack broke and got a replacement at radio shack and has 3 sqrews in it have red and gold then other two are green and gold how do i hook up?

Some jack cables contain enameled wire, which are red and green. These cables need to be stripped back before they can be solder or put together. Try scraping the ends with a sharp knife or with actual cable stippers. The red and green cables are right and left channel respectively. The gold ones are ground and must be soldered to ground, which could be just any metal part of the jack, not insulated with enamel. Also, if you are going to solder, you should just hold these cables together by twisting to see if you can get sound out of the connection.

Replacement connector for Sennheiser PX 250 doesn't work...

The bare copper conductor wire is the screening/common earth to the two signal wires of green and red. The important connection is the copper wire which goes to the jack plug earth which is the section furthest from the tip. The other two are the left and right signal connections. If you get these the wrong way round you will just have to swap them over. Check if they are the right way round by using the balance control on your amplifier or whatever. Have you checked that the problem is not with the headphone amplifier within your equipment? Don't rely on OK sound from loudspeakers as the headphones may be fed from separate op-amp output chip. Try another pair of cheap and cheerful headphones to make sure.

Jack plug broken off

Buy a $4.00 1/8" jack replacement from Radio Shack - part # 274-0869, which has small screw connectors that don't need soldering.
Strip about 1" of the braided insulation at the old jack end, which will expose 4 very small wires: Blue, Green, Red, Copper.

Attach the Green & Copper wires to the tallest pin on the replacement jack.

Attach the Red to the shortest pin, and the Blue to the medium pin.

Remember to slide the jack cover onto the headphone cord before attaching any wires!

This works great, I just did it.

Dog chewed through Turtle Beach X1 wire any advice on fixing??

Your best long term fix will be to solder the wires together then tape them individually and finally tape the whole thing. Second choice will be to use crimp (**** splice) connections and then tape. Last choice will be just twisting stripped wires together and tape everything.

Tdk mp100 headphone jack

Each of the rubber covered cords running to each ear piece has two fine strand wire bundles inside. The right ear piece has a red colored strand and a copper colored strand. The left ear piece has a green colored strand and a copper colored strand. The wires are coated with an insulation lacquer. The lacquer burns off when you heat the wire for soldering.

Repair item: 3.5 mm stereo headphone jack, shrink tubing

Plan for strain relief:. These headphone wires can't take any tension at all. You need to crimp the black cords to the headphone jack somehow.

Slide strain relief and headphone jack housing over the over the rubber covered headphone cord.

  • You need to plan a way to relieve the pulling stress on the solder joints where the two headphone cords enter your replacement headphone jack.
  • Try shrink tubing if you have it.
  • If you have some thermal shrink tubing, slide a piece over the headphone cord end before stripping the wires.
  • Slide the headphone jack casing over the headphone cord also.
Strip each headphone cord 5/8" using the 18 gage setting of your wire stripper..

Hold each headphone cord in a "third hand" soldering assist tool and tease the green, red and copper bundles apart..I wore a 10x Magnavisor and I used a sewing needle and a bright light.

Twist the copper colored strands from both headphone cords together. They are the common ground wires. The copper colored bundle will attach to the headphone jack ground.

Apply a dab of solder to the end of each of the three bundles of wire. You will see and smell the insulating lacquer as it burns off. Keep most of the wire bundle cool.

Position the two strand headphone cord and the 3.5 mm headphone jack in the third hand soldering stand.
  • Plan where you can crimp the headphone cord. Crimp it when ready.
  • The green == left channel wire goes to the tip of the 3.5mm jack.
  • The red==right channel wire goes to the middle of the 3.5 mm jack
  • The copper colored wires go to the ground of the jack..
  • Measure resistance, 31 ohms per earpiece.
  • Screw the jack cover on and finish the strain relief craftsmanship.

Wire has been cut

My wire was cut, and I made it worse trying to fix it....with several failed attempts... was becoming despondent, but gave it one last try, and was successful. First, each little tiny wire has two internal wires, one green (ground) and one gold (hot). At first, the green one looked like some fiber or filler and I cut it, connected the gold wires and nothing happened. On further inspection, with magnifying loopes, I determined the green fiber was in fact green wire. There was also a lot of clear fiber, which is insulation? filler?... I don't know, but I cut it out, leaving only the wires. From the internet, I determined that the wires had a thin layer of plastic on them for insulation, which I burned off lightly with a lighter, connected the green together, soldered it, wrapped in electrical tape, then connected the gold together, soldered it, and taped again....and to my suprise it worked. I used twist ties, and epoxy to strenthen the area and was done, my headphones are working again.

Basscube remote knob wire


funny seeing this question posted here... I worked at Phoenix Gold for 4 years, and I can help you with your problem.

when the BassCUBE was designed, the engineers didnt realize that a standard phone cable is what we call a "flipped cable", where if you were to lay the cable flat without any twists in it, on one end the connector would be tab up, and the other end would be tab down. on a standard RJ11 plug (the phone plug), the telephone requires that the pinout is as follows:

#1 - Black
#2 - Red
#3 - Green
#4 - Yellow

But the BassCUBE needs a non-flipped cable, which are hard as heck to find... so I will give you the quick easy fix.

You need a 2-line (4-wire) telephone cable that has a black, a red, a green, and a yellow wire in side it, and you will need 4 crimp caps or other way to splice the wires back together. You then need to cut the wire in half, and carefully seperate and strip each wire on each piece of the cable. Call one piece "Part A", and the other piece "Part B". Then you need to splice the cable back together as below.

Part A Part B

Black ------------------> Yellow
Red --------------------> Green
Green -----------------> Red
Yellow ----------------> Black

Once you have done this, and your SURE that your splice is good (not shorted out), then go ahead and plug your modified cable into the BassCUBE and its remote control, power it up, and you should be good to go.
