Title: what happened to headphones with 1/4 plug?
Post by: K2JF on August 01, 2018, 05:49:00 PM
Is it impossible to find a set of decent headphones that terminate in 1/4" plugs? Everything has the 1/8" plug and the 1/4" adaptor. What's the big deal about a set with the 1/4" plug? Find me one!!!!!

I think the Kenwood HS-5, designed for radio communications use, is still available.

And you can still get NOS Telex mono headphones on ebay for about  $10 a pair.

but how will the mono headphones play with the Yaesu FT 950 whose jack is wired for stereo??

I kept my 40 year old RadioShack stereo headphones with a 1/4" plug.  Still work great!

I threw away the army surplus headphones with chamois muffs (that terminated in a 1/4 plug) I had long ago. I bought them from that surplus store in Lorain OH ... not remembering the name of it. Never did use the throat mike. Are those the ones your thinking about?

Now, I use a $70 Bluetooth connected headset. It has a 10 hour run time & recharges in maybe a little more than 30 minutes from dead. 10 hours is a long time even with a headset on. Also has 7.1 sound in case I listen to something else. My SDR uses stereo thru the headset to help separate CW signals ... getting back to ham radio. ::)

I do have a headset with a 1/4 plug. Stiff as h---. Gets caught on a sheet of paper. PITA  Sorry for being a jerk. But, I don't like the old stuff I had.

Not be snide, just curious...

What's your issue/concern with phones that use the 1/8"-to-1/4" adapter set-up?

What would be the advantage to phones that come with a 1/4" plug installed rather than the adapter st-up?

If you don't want to use an adapter, why not acquire phones that you like and cut-off the 1/8" plug and install a 1/4" plug?

Depending on the circuit design, there may be no problem just using the mono plug in the stereo jack and
no harm from possible shorting out of one branch of the mono circuit. I'm quite sure that FT 950 isn't playing
in hi-fi stereo.

My guess is that rig is from a time when both stereo and mono headphones were available. There may be
a note in the manual.

On my rigs (which use 3.5 mm stereo jack wired for mono) I use 3.5 stereo plug to 1/4 inch adapters for my mono headphones. No problems. Circuits are appropriately designed.

I make the adapters or, in the case of the one I usually use, I buy a relatively expensive namebrand adapter (I think mine is a Sennheiser). Most of the cheap adapters available on line are poor quality and quickly become intermittent.

 I think the reasons why headphones are now using 1/8" plugs is because everything is becoming smaller. 

You have a few choices. 1/8 to 1/4" adapters; cut the plug off and replace it with 1/4" or go buy a off-brand set of headphones with 1/4" plugs....usually NOS.

The market for 1/4" headphone plugs has dwindled down to the point where it isn't economical to make them.

What I like to do is use a low profile 1/4 to 1/8 adapter, then put a right angle 1/8" connector on the headset if it doesn't already have one.  Now the cord isn't sticking straight out of the radio and can be routed out of the way.

I make low profile 90 degree 1/8 connectors by taking a solder on 1/8 plug, bending the shield/strain relief back to 90 degrees from the plug and soldering the cable to the lugs.  Then I encapsulate it in 5 minute epoxy along with a bit of the cable to serve as a strain relief.

Easy, peasy non-issue fix.  In fact, most headphones today are really good and lightyears better than the old 1/4" plug mono headsets of the past.  Heat up the soldering iron, and cut off the small plug.  Get a good quality metal 1/4" plug, and solder the leads to the tip and shield connections respectively.  I did this to a Sennheiser HD25-1, and works perfectly.  No, they're not 8 ohms...matters zero at these audio levels.

Be careful cutting off the stock 1/8 plug and trying to replace it. You may end up ruining a $100 headset. Many of to-day's headphone cords are made of several strands of cotton thread each wrapped with a thin strip of copper.  Some don't even appear to be made of wire, but fibre thread impregnated with some kind of conductive compound.  This makes them flexible, but very difficult or impossible to make a secure solder connection.

I've been there and done that - cut a connector off the headset and found the non-metallic thread. You can't solder to it, all you can do is crimp it. I've had limited success with winding some thin copper wire around the thread, crimping it with pliers and then tinning it with solder. Messy!

I'd just make a short adaptor cable a few inches long with a 1/4 inch plug on one end and a 1/8 inch in-line jack on the other. That way you can bend it any direction you want as it comes out of the 1/4 inch plug. I've purchased 1/8 inch extension cables, left the 1/8 inch jack wired as-is and cut the cable a few inches from the jack then solder a 1/4 inch plug on the cut end. That way you don't have to deal with making connections on the small in-line jack.

K2JF,

Your call sign is extra class?

And folks, head phones are not monaural. They are stereo, left, right, stereo.

If it's the same wire I've seen for years...it's usually enamal coated so you can have two strands without the need for jacket insulation to prevent shorting...it's just really hard stuff to solder.

I usually have to take sandpaper to it before it'll take solder...and even then it's just at the melting point of the solder.

Then again I haven't bought a pair of headphones worth repairing in the last 10 years.

And ....technically...headphones are binaural, not stereo. There *is* a difference. You can listen to stereo content...and they do reproduce stereo...but it's not "true stereo". If you've ever heard something mixed for binaural it becomes very clear.

Binaural is correct.

My headphones I've had since Christ was a corporal are simply a 2 inch speaker in each side. Silly actually but what else would work. And I've seen headphones for $200.00. Gollee!

Have fun.

The cotton with thin copper tape wrapped around it was used on headphone leads pre WW2. In those days, they wrapped very thin wire round it and formed it and then formed the whole thing into a loop that a screw and washer could compress down. Later on, they crimped tags on. Used on some telephone handsets up until the 1960s or so I believe.

According to Kenwood, certain rigs they manufacture will produce a hum in the headphones with the volume turned all the way down.
They recommend using an 8 Ohm set of headphones to cure this.

I have two pair of 1920's vintage Western Electric cans...4000 ohm. The cat's pajamas in cw with my IC7200.
