How To Solder a 3.5mm, ⅛”, or Mini Headphone Connector


Hi I’m Benson with Linxus Communications Today we’re going to teach you how to
correctly solder at 3.5 millimeter connector the 3.5 millimeter connector also known as
mini plug ⅛” Jack or your common headphone
jack can be used to plug into an mp3 player a CD player or a stereo. For this project you need a solder station or solder iron helping hands, 3 connector wire, solder cable or wire strippers, a de-soldering
tool or solder sucker, snips, an alligator clip or heat sink and the connector. This
particular connector is sold by MCM electronics and features a
nickel plated housing there are many reasons why you may need
to solder a jack my have a loose connection you may need
to create a custom length cable or more than likely you’re running a
cable through a table or wall weather isn’t enough room for
the connector itself. First you’ll want to get your soldering iron
warmed up by making sure it’s plugged in or making sure the batteries are
charged. While that’s warming up dampen the sponge and set up the helping
hands to hold the new connector immediately slide on the screw on
cover over the cable it is much easier to do this now before
you strip the cables because you will not have frayed wires
catching and there’s no putting this piece on after you’ve soldered the connector.
Strip the outside jacket back two inches Remove any metal shielding. Trim any
strings find as well. Strip each inner cable back about one-quarter inch in front of the
jacket. Don’t worry about the length yet we’re going to cut them down later. If
your cable gauge is larger than your connector hole visit this link. If your cable gauge is
smaller than your connector or visit this link. Be sure to twist any stranded cables. Place the clip or
heat sink on the wire close to the plastic sheath and tin the ends. Tinning is when you heat
the wire and allow the solder to soak into the
tip. Done correctly the wire should actually soak up the
solder. You shouldn’t have to touch the iron directly to the solder. Some solder is toxic so try not to inhale the fumes. A hood or
well ventilated area is highly recommended. The tip or left channel goes to the
smallest lead or metal tab with a whole The ring or right channel goes to the
middle lead. The sleeve or ground goes to the large lead. This is the universal to all brands. A
proper solder will be just a shiny after it cools as it was on the spool. To do this you
need to keep everything perfectly still this is why I’m using the helping hands.
Now clamp the wire down to reduce cable strain. Don’t over compress and regularly clean the solder tip on the sponge. Insert the
wire all the way to the metal you want as little metal as possible
showing this limits shorts. Always use the
soldering iron to heat the joint not the solder. A small amount of solder will help the
joint conduct heat much more efficiently this will cause the solder to be heated
by the joint wherein it will soak into the connection
resulting in a much stronger joint if one on the solder
points are bad you can start over by using the solder
sucker. Be careful when you remove the heatsink it could be hot. Place it on the
middle lead and repeat the process. Twist one or both grounds together and
insert into the ground. Solder into place. Check to see if there
are any shorts. Trim the excess wire any strands that
were missed. It’s not a bad idea to add a little
electrical tape to prevent any future shorts. Clamp the ground lead around the wire.
Pull up the cover and screw on. Now unclamp and test. If you follow these
directions should have a connector that lasts for years! Thanks for watching. Don’t forget to LIKE

  1. Miles better than most of the "how to fix your headphone cable" video's helped me fix my £100 TDK headphones, only thing left out is how to tell left channel,l right channel and earth apart,

    Generally red is always right channel as far I can tell  

  2. hola amigo como le va ? 
    te hago una consulta tengo un problema . le quiero instalar un  3.5 mm jack HEMBRA para mi amplificador tiene radio  y conexión vía bluetooth y no tiene entrada  de auriculares  tu sabes como es la configuración para poder instalarlo ? e buscado un video que me hable de ese tema y no lo hay, y tampoco fotos que  muestre bien el armado o el diagrama no lo veo .  ya agote mis recurso, por eso te pido esta ayuda ,,,,  yo quiero separa el audio del parlante con el auricular  yo se que el 3.5 mm jack HEMBRA cumple como un interruptor cuando conecta el auricular

  3. Fantastic video.  I've soldered and desoldered components on PCBs before but I needed the method for these plugs and this is excellent.  With all the equipment, it's costing me much more to do one plug than buying a new cable, but I'm doing it anyway because I want to have fixed it myself instead of being a helpless, skill-less consumer of disposable resources.  Ordinary people can do a lot.

  4. Good video. Here's a Pro tip -Wet Sponges (as shown in the video) are good for the casual user, but if you are planning to use your solder iron a lot I recommend not using a wet sponge and instead use a dry wire sponge (like the ones Hakko makes).  This type of dry sponge makes your iron tips last much longer because  you are allowing the iron tip to stay at a stable operating temp instead of sudden intermittent shocks of cool water which have an effect of annealing the metal and changing it's ability to transfer heat over time. Also a wire sponge creates less fumes and doesn't have the solder vapor coming out for you to inhale.

  5. So been watching a few videos and none including this had info on which wire was left a which was right.  and which was the microphone wire.  I understand your cable doesn't have a mic but I feel it would be good to explain that to the lesser informed and newbies like myself.

  6. I know this is silly, but your nails and cuticles are a hot mess, and it actually distracted me from what you were doing. I was transfixed by the number of hangnails and the jagged nail edge. If you're doing videos like this, not overclipping your nails (they are so short as to invite nail infection and growing into the fingertip ) and moisturizing your cuticles a bit will go a long way toward making your hands look nicer and thus your videos more professional! Great video otherwise and nice clear instruction!

  7. This is a well presented tutorial. I liked the finishing touches too (Don't inhale smoke, and visual hrefs on the video iteself). Good work.

  8. First class YouTube education. This was great information, well edited and concise with pleasant music playing in the background without being overbearing. Well done guys and thanks heaps.

  9. When i test my left and right speaker all my speakers go on when left plays but when right plays nothing happens? can you help me?

  10. Hi! Hope anyone could enlighten me with this.. I'm trying to make an adapter from Female RJ10 4P4C to Male Audio/Mic, but I am not sure if this is possible.. I would like to know if the cabling or pinning will still be like 
    1-BLACK
    2-RED
    3-GREEN
    4-YELLOW 
    WHICH
    FOR MICROPHONE:
    1-BLACK
    4-YELLOW
    FOR AUDIO OUT:
    2-RED
    3-GREEN
    I am actually trying to use my headset with RJ10 PLUG, that's why i'm thinking of making the adapter myself since I have all the equipment needed.. Also I'm opting to use the cable of my old headset with microphone and volume control for the Audio/Mic Jack, but I'm having a hard time searching if where to specifically attach the cable from RJ10 to the small-motherboard of my old headset cable. Please enlighten me folks.. Thanks ahead of time…

  11. Buyers beware. I've run across commercial 3.5 mm cables that are wired wrong with the tip positive and ring negative. Always check any of these types that you buy. Most are from China!

  12. Good video thank you- I'm trying this in the next couple of days. I thought that transparent plastic sleeve was heat shrink and would require heating, is it not? Thanks.

  13. hi, i replaced my desktop speaker 1/8" connector recently. but after i tested it sounded a little reverb than normal. maybe i mixed the wires?

  14. any recommendations for the best value and/or quality 3.5mm connector? or should i just pick the one with the best reviews on amazon.

    noob question, but does it matter if the connector is of good quality?

  15. @Dixon Hill Hey, thanks for the uber informative video helped tons. I was too a send you an email or private message or something but I'm not hip to how you tube works like that so I guess I'll just ask here.
    I have a tip unlike the ones you used with0 holes only wings and bare access to the poles how do I do it on these?

  16. the most informative and easy mini jack replacement tutorial I found, thanks, will follow it as soon as I get the jack

  17. ok, i've got mini jack with upper and lower ends, not right and left like here. I suppose upper is for right channel and lower is for left channel?
    also, i have 2 pairs of headphones and attached both of them without soldering to see if they work. One works, the other does not make a sound. What may be wrong? Before the process both pairs did produce sound.

  18. My earphones has 4 wires, green, blue, red and orange. They're called bassbuds. I don't know what to do

  19. Thank you for saving me buying another 250 dollar pair of Sennheiser headphones , im a bit of an audiophile and can tell when the third violin is out in an orchestra. Music is life and you just helped me in my efforts to explain to my wife why the expense was crucial to my mental health…. lol and nothing against Sennheiser they're a premier product my (someone strong) toddler got a hold of my head phones in my room (she scorns child safety products such as child doorknobs, toilet locks and the like.

    Anyways she loves music too god bless her, but when she was trying to steal my headphones she ripped them sideways out so half the jack bent sideways tearing the wires from the jack.

  20. could that jack be used one old external speaker to input TV (headphone) jack connector. speaker only has blk n red push clamp connectors.?

    thanks inadvance!

    larry

  21. I have a pair of Sony pro headphones and the conductors are green, brass-colored and copper-colored, with no apparent insulation on them at all. How does that work?

  22. Hey, if my cable is a mono microphone output and I have a stereo jack, can I solder the cable to both channels simultaneously and have it working properly?

  23. This may be way outta your league, but I have a vintage dynamic microphone with the 1940's jack 4 pin jack on it, and I would like to make it use 3.5mm or USB jack instead. Could someone send me a how to video?

  24. For a beginner…I was completely lost at 2:44 to 2:56. I wouldn't know which is the left or right channel or ground..even if the jack is propped. So i'm assuming the tip has to point to the right in order to figure that out. I like to think that it would've been easier to distinguish by the color of the cord ( I thought they have some universal color code)

  25. Your video is by far the most informative one that I have found on this subject. Other videos I've watched were sloppy, had annoying music, and moved too quickly through the process. Some didn't even identify which prongs went to the tip, ring, and sleeve. I give your video an A+ for a first class job! Please continue to enlighten us with more instructional videos. This is the way you do it folks.

  26. Very informative video. Thank you very much, I'm currently trying to do the detachable cable mod on my headphones.

  27. Thanks for the video but I am still not sure which tag the red cable goes to, I don't want to connect reverse polarity, any help please.

  28. Hey! you make it look so easy with those big strong wires but the portable headsets of senheiser have wires like hair follicles

  29. Learning. I'm having a hard time getting the wire/joint hot enough to melt the solder. I'm using a small amount of solder to enhance the transfer of heat, but still I can not touch the solder to the wire and have it melt. .032 dia light duty 60/40 rosin core.

  30. THANKS, GUYS! Well done, informative, helpful, brief, good pictures… An amateur like me fixed such a connector, which saved an old set of small speakers from going into the trash. 🙂
    NOTE: My el-cheapo speaker wires consisted of only a few tiny strands, with one white-sheathed and one naked set of strands on the left half, and one red-sheathed and one naked set of strands on the right half. I had to carefully strip the white and red sheaths before tinning them and attaching them to their respective posts. I combined the two naked strands and attached them to the ground post.

  31. I'm trying to find out, which cable I should solder on my left/right channel.
    This is a solder tutorial, not a 'how to solder headphone connector'

    Good tutorial but not ideal.

  32. Sir, very informational video…would like to ask could you plz show us how to make 3.5mm mic jack to micro usb and usb.

  33. If you have 5 wires , two unshielded copper wires, one green,one red , one blue.
    Twist the copper wires together which are ground,
    Red is for right , blue is for left, and green for microphone.

  34. Great video, im wondering is the solder the same to those headset with 2 separated connector for mic(pink) and phone(green)..i mean is the scheme the same for the pink one? much love from brazil

  35. I bought a hand made cable with a 3.5 mm Neutrik jack.
    Went bad after 1 year (there is visible dent in the 3.5 mm jack, not deep, but visible from normal usage).

  36. Great video, thanks!
    QUESTION: Why does the linked video (https://youtu.be/In8QisKLYKk?t=2m6s), for too-small wire, give instructions to make it even smaller? Anyone know?

  37. How long do you need to hold the iron on a braided wire until hot enough to melt the solder that is touching the wire (for tinning)?
    How long needed to hold the iron on the terminal to heat the solder that is touching the terminal-to-wire joint?
    In each case, I hold it there for what seems like minutes (maybe it’s only a minute?) while I feel the solder hot between my fingers, and the wire hot between my fingers, but the solder ain’t melting?
    How can the solder I’m holding be so hot that it hurts my fingers a bit, while the heat at the point where the solder is touching the wire or terminal that the iron is heating is not hot enough to melt the solder????

  38. This will not work well on modern connectors, the connectors are the same , but the wire used today is totally different. There is nothing to strip, the conductive part is on the outside and is lacquer coated. This video deals with what is more or less 1980's technology, most are not made like that anymore. Here is what it looks like today: https://www.youtube.com/watch?v=f_OL9KoIFVM

  39. 0:11 – The "plug" is not known as a "jack." It always amazes me that people can't keep the definitions of "plug" and "jack" straight.

  40. Thank you so much for this informative video – showing us the CORRECT WAY in which soldering should be done.
