I really hope you can help me with this as no one could answer it before.
I am using a Rode SC6 Dual TRRS ( and want to do connect my headphones output of my laptop with the microphone input of the Rode SC6 to directly get the sound from my laptop into my phone. I already bought this male to male 4 conductor but it doesn´t work ( 
Please can you help me what I can do to make this work?
Thanks a lot.

Just wondering, why do you want to get the sound from your computer to your phone?
Edit: It might also help people give an answer if they know exactly what you are trying to achieve

Hi CRolls, it is a bit complicated to explain it. I am a mobile broadcaster and do skype interviews with guests from all over the world. I would love to improve the sound experience for my viewers by directly getting the sound in my mobile instead that they need to hear my skype partner from my speakers. I hope this explains it a bit better. Any ideas?

So you are after something that could convert an auxilary output from a device (for want of a better explanation) to a microphone termination so it could be connected to a phone as a microphone source, it could be done easily with passive cabling I just dont know how to find it on the internet. I think the cable would be like this
                                    3.5mm cable
            left------------------------------------------------------------------\      unused
pc         right---------------------------------------------------------------\--\     unused     phone
                                                                                                             \--\---microphone pole
this cable could come from a splitter so you could also monitor the audio from pc with headphones, I dont know if a cable like this exists but you could make one yourself and sorry if this diagram makes no sene to anyone but me
edit: just thought of a potential issue, the mic input is meant for low powered sources so unless the volume was kept very low this would potentially destroy the mic input on the phone

The cable should work on all phones but as I just added in my edit, the output from a pc would be much too high power for a microphone input. So I acheived nothing in all that typing :)

@labrat: Hi, Thank you for your answer labrat. If you click on the link above u see that I have 2 mic inputs and 1 headphone output as I am using a splitter so I hear them and they hear me. The only part which is missing is my problem described above. 
@Crolls. Dont understand unfortunately you scribbling but there must be a way as others are doing it, too somehow but I dont know how and cant ask them  -.-

@Labrat: Yes, my splitter (Rode SC6) has it and I plug it in to my phone. I would also have an Samsung S4 if this works better than an iphone.
My computer is max book air so just one headphone output.

Don't worry about my scribbling, after posting, I realised it would not work :)
Your Rode adaptor has 2 TRRS inputs for microphones, and they advertise you need to buy an adapter to make a microphone connect to either of the microphone inputs.
And what is "smartLav" ?
So you neeed to find what the pin-configuration of the TRRS inputs are, they are probably not standard.
What microphone have you tried with this adaptor?
And your Apple MACBook Air has one output, a TRRS to headphones and microphone.
So you need to break up the MACBook output into 2 headphone outputs!
A break-out cable with a TRS-connector so not to trip the microphone-input of the MACBook to look for an external microphone.
I guess you are using the internal microphone of the MACBook?
One to connect to one of the microphone inputs on the Rode, the other to connect to a speaker so you can hear what goes to your phone.
Nothing is straight-forward!
But doable.

Wouldn't the output from a macbook be much higher power than a standard microphone (as microphones are passive normally so mic level is 0.001 volts whereas line level is 1 volt) causing the microphone input on the phone to be damaged from being overloaded, I am not sure, just want to make sure that we dont accidentally talk the op into damaging his gear
