Stereo to Mono adapter question Headphone Amps

Stereo to Mono adapter question

This is a super-simple question for the right person. I just wanted to get another opinion before placing my order.

One of the Producers that I frequently work with is deaf in one ear and is looking for an adapter that will sum stereo headphones (3.5mm) into mono in both ears. What is the simplest way to do this?

Seems like I need a male 3.5 TRS to female 3.5 TS. I just want to make sure I'm not just getting left or right, but rather a summed stereo.

Thanks!

Yeah...If you have a 3.5mm end on your headphones, you want this:

splitting a signal to a pair of inputs is OK, combining a pair of outputs isn't - transistors aren't happy with another transistor trying to cram their signal up it's output. unless you know the particulars of the headphone amp circuit, you're better off making a summing network in a small project box:
Why Not Wye?
your circuit will resemble fig.2, except that your output jack will be trs, with both t & r coming from the node common to all resistors.
The values shown are for line-level circuits - you may want to push the 470's up or down to better match your headphone driver impedance, and use resistors @ double the wattage rating of your amp outputs.

This is easier:

I have been looking if such a thing exists and I cant find the one I am looking for....

I have a tuner with a cassette player hooked up (double cassette player) and I only have 1 speaker so the sound would not be good in stereo.... (I really prefer MONO anyway)

Are there any stereo to mono adapters for a cassette deck (A pioneer) that hooks into a sony tuner?? (Its got standard cables for left and right channels)

Why not just send him a summed mono signal from your DAW?

Something is only stupid if you don't understand it.

The reason why most things don't have a mono switch is the majority of people have two working ears. But in this situation the person the OP mentioned only has one working ear. Another reason is if you have a PA situation (like a school or mall) so it's set up so that every speaker plays the same sound.

As for why FM radio has a mono switch, FM started out as mono and the system for FM stereo designed over 40 years ago actually weakens the signal and causes varying amounts of noise in radios, even under ideal situations. So the idea is when you're on your favourite station and it's noisy you can hit the FM-Mono switch to cut the noise level.
