Title: Headphone pet peeve : 1/4" to 1/8" adapters
Post by: Ryan Massey on January 14, 2011, 01:53:26 pm
Quick rant:
Now that so many clients come in with laptops, Ipods, etc., I can't keep the damn 1/4" to 1/8" threaded adapters on the headphones!  And far too often, they are simply getting lost.  I am seriously considering cutting off all of the TRS plugs from my headphones and hard wiring new ones that are 1/4" only.  

Even more annoying (and perplexing) is that the Sony and AT phones use a different thread, so a handful of the new adapters I bought are doing me no good at the moment.  Arrrgghh!

That's what I ended up doing.  (It's fun with the Litz wire Sony uses.)  I tried putting heat-shrink tubing over the adapter but that only slowed them down.

That Litz wire is a bear, the only way I could get solder to stick to it was to put it under raw flame to burn the coating off.  It sure makes the wire brittle at that point.  Any techniques to solder them?

I have just burned off the insulation by tinning with solder.  An iron hot enough (~700

I don't believe that it's Litz wire.

It's 'Tinsel wire'.

Litz wire is a piece of cake to solder by comparison!

Ah, so it is.  At least they didn't use knob-and-tube!

Superglue. (for the 'built-in' adapters)

And bright-colored 1/4"-to-1/8" adapters; keep a quantity in a locked drawer and make only two or three visible per session.

IDK about the USA, but here they can be found in red.

If you can't get them in color, get the black ones and paint them pink with nail polish.

Loctite?

EDIT:  YZ beat me to it.

Yes, tinsel cable is not meant to be soldered.

Crimp tags in all those PO-gauge patch leads, last forever.

Yup, I replace all the ends with 1/4" on ours. We keep a few pair of headphones with the mini jack, just to have. For iPod, etc, playback, I have mini to TRS 1/4" cables that feed into a panelmounted TRS jack connected to a Matchbox which is wired to an External 2-Track input on the desk.

Those little adapters can be shockingly expensive.

Loctite! Brilliant!

I'll give that a shot first before I pull out the iron.  I don't think the AT phones suffer from the lousy tinsel wire, so I'll replace those before bothering with the Sony's.  Thanks!

Don't forget that most locktite is a wicking sealer. Meaning it will try to make it's way to any nooks and crannies it can. It might end up insulating the audio contacts over time.

I think Loctite is basically CA glue, like Krazy glue.  Once it sets, it becomes very hard and should not move or migrate.  If you put a  very small drop on the top of the adaptor (where it meets the body of the jack) with the adaptor firmly screwed in place, you could probably 'lock' it without disturbing any electrical paths.

Krazy glue might work just as well, and be cheaper.

I am dubious but curious about this:

Loctite is anaerobic methacrylate resin. It hardens in the absence of air. Cyanoacrylate glue (superglue) hardens in response to the moisture content in air. Two different adhesives.

+1 for Loctite red.

Or if you never, ever want to get the adaptor off, Loctite 270.

Beat me to the punch on this major pet peeve.  Those darn adapters keep breaking (two this week alone!) and the replacements I bought don't fit either.  Arrrrrggghhh indeed.

"Loctite is anaerobic methacrylate resin. It hardens in the absence of air."

...and they don't cure very fast (at all?)on certain metals and platings without a primer.

There are plenty of good 5 minute epoxies out there.

Maybe this idea can be helpful to some of you.

I leave an unthreaded adaptor in the jack and pull the miniplug out.

Shrink tubing works if you position it just right so it overlaps the lip on the adapter.

Unbalanced insert cables make great replacement headphone cables.
