Breathe New Life Into Old Headphones





Introduction: Breathe New Life Into Old Headphones

Fix & Repair Contest

Fix & Repair Contest

I found this sweet set of Alpha Electronics vintage headphones at a garage sale today for $1.00. I couldn't say no to this awesome old school style! Unfortunately, they were in slightly rough shape and since they are so old (I would guess early 70s), they used the 1/4" male audio jack which most of today's audio listening equipment doesn't use anymore. I knew with a bit of slight modifications and a little TLC, I could bring these old headphones back from the dead!

What you'll need:

-Vintage headphones

-Female 3.5mm stereo audio jack

-Male to male 3.5mm stereo audio cable

-A rubber grommet

-An audio source


-Soldering iron and solder

-Helping hands (not necessary, but they make things a bit easier)

-Varsol (paint thinner/mineral spirits) and paper towel for cleaning

-Epoxy glue

-Electrical tape


Here we go!

Step 1: Cleaning

The first thing I did was put a bit of Varsol on a paper towel and wipe down the entire set of headphones to get all of the dirt and grime off of them. They were pretty dirty, but actually came out pretty nice after some serious scrubbing.

Step 2: Remove Speaker Cover and Cut Old Cable

Now just get some scissors or wire cutters and snip the old 1/4" jack and cable off as close to the headphones as possible.

Next, remove the earphone cover on the same side as the original cable went into.

Step 3: Solder on Female Jack

Now, get your female 3.5mm jack and solder the three wires you just cut to the three terminals of the jack. In my case, the wires were already properly colour coded (red=right, white=left, black=ground). Just strip a bit of the jacket off of the end of the wires and solder them to the terminals.

Step 4: Prepare Grommet and Secure Jack

In my case, I had to cut the grommet in half because the threads of the 3.5mm jack weren't long enough to go all the way through the full grommet. I simply cut mine in half with scissors.

After your grommet is ready, hold it on the outside of the earphone body and feed the threads of the 3.5mm jack through from the inside. Then screw on the end piece of the 3.5mm jack to hold everything together.

Step 5: Glue

Now, mix up some epoxy glue and glue the rear of the 3.5mm female jack in place just to keep it from moving when you plug and unplug the male cable.

Step 6: Ear Cover Repair

One of my earpiece covers had a couple of small tears in it, so I cut a couple of pieces of electrical tape and patched them from the inside.

Step 7: Reattach Ear Cover

Now, just carefully stretch the ear cover back over the headphone.

Step 8: Done!

Now, plug your audio source into your restored headphones via your male to male aux cable and blast some tunes! The one downside to using these massive headphones with a battery powered audio source is that they will probably drain the battery much faster than earbuds or other small headphones, but they look so cool!

I hope you enjoyed this Instructable!

    Great restore though because these old cans where designed for big current amps and modern mobile devices don't pump out that sort of power I tend to replace the speaker drivers as well ( just some hacked out of a cheap £15 to £20 set of modern earphones ) that way you get the same performance of a modern set with all the kudos of their retro styling, also older cans tend to be much more robust and sturdy

    I have a decent set of phones but can't get sound without the jiggle techniq.would love to rewire and wondering where to get 2nd hand wires from.thx cool idea of yours.?

    Hi there,

    You can salvage wires from all sorts of old electronics that you may find out on the curbside. It's been a while since I did this Instructable, but I remember the original wiring was nothing fancy (I think maybe 20 gauge stranded copper). If you are talking about the coiled cord itself, you could buy something like this on eBay:

    And then just cut off the female end and wire to the headphones.

    Cool work !

    These vintage phones must be 8 ohm, and speakers in them (usually) wouldn't sound superb. The chassis of the vintage phones is something they don't make anymore (cutting production expenses). I am working on a similar project, besides, taking the speakers from modern KOSS (the plastic squeeky sound of a cheap chassis just killed the joy of listening), remaking the earpads in real leather and insulating the inside of the cans for better sound.

    Wish I could get hold of cans this fancy


    Yeah They're pretty nifty cans I have to say. If you're really set on getting some similar, I see them at garage sales fairly often for next to nothing, Seriously, like $0.50 - $1.00. I would say garage sales are your best bet for finding an old set like these. They don't have the best sound quality in the world, but for 40 year old haedphones they actually sound pretty good haha. Thanks for the comment and good luck on your project!

    some of these folks can communicate via keyboards so I imagine they can read . thats why i'm commenting I got my first radio in1963 i was 6 years old it almost fit in a pocket .haha . lts still in my folks house somwhere .I get a warm feeling in my gut whenever I see 60' 70' even 80' tech . please dont run into the future blind . the bogus wires were fixed hahas .

    I'm actually doing the same thing, really helpful.

    Glad I could help. Post some pics when you're finished!

    cool!!! thanks for sharing.

    Thanks! Glad you liked it!
