Hi all,

I have two headphone amps, one Solid State and one Valve... and a Switch.

I want to plug a single pair of headphones into both amps, then use the Switch to... um... Switch between them. This is mostly for convenience, but I also want to do some A/B testing.

I have tried to find a cable that is 2x6.35mm Male to 1x6.35mm Female (or 3.5 mm) TRS, but the only ones I can find are for Headphone/Microphone into a phone or PC etc.

The issue is that if you try to use the Microphone single-end for a Headphone, it does terrible, evil things to the signal. Or at least the two that I have both do. Maybe I am doing it wrong?

Does anyone know of a cable, or other mechanism, that would allow me to do this?

Thanks in advance!

What type of switch do you have?
A 2 input, 1 output type?
Presumably it's something with its own sockets?
If so, what are they?
Are you (or someone you know) OK with making your own leads?
Ok so it is:

Schiit Sys
Website Link

Number of inputs: 2 (stereo RCA)
Number of outputs: 1 (stereo RCA)
Input impedance: 10k ohms
Output Impedance: 5k ohms maximum

And I am using the output as the input, and the inputs as outputs.. which the website says is just fine.

Now that you mention it I do actually know a guy that used to be an Electrical Fitter... he might be able to help me out! I am not handy... a friend of mine bought me a drill as a joke birthday gift once, and my wife threw it out in case I tried to actually use it.

:) Maybe steer clear of a soldering iron then.

The Schiit Sys is OK for selecting which of your amps gets the Modi out on their input.
But you want to switch between 2 headphone outputs - in which case you need just a straight switcher like:
(Ignore the single 3 star review which mentions a PSU, the switcher doesn't use one).

With one of these (available in 4 different lengths) plugged into each of your headphone outputs:
No soldering required (y)

OK... I will remove the soldering iron and heat gun from my Amazon Cart.. and cancel the extra fire insurance I just took out ;-)

So... I would just have to switch the SYS and and the Nedis at the same time... I can totally live with that.

Thanks so much for your help, I am very grateful!

If you were to find it that it isn't fine, another of those Nedis switchers would certainly work.
(Maybe shop around by the way - just saw them cheaper on Amazon than e-bay).

Up to you, but personally I don't like don't like 3.5mm sockets. If your headphones have the full-sized jack, you might prefer to use another 6.3mm to twin RCA lead connected to the rear output sockets and couple it to your headphone plug with:

That's an elegant solution... much appreciated!
