strange problem with a in ear earphone

[djsolidsnake86]

i have a pair of xiaomi mi noise cancelling earphone (3.5mm jack)
i want use this on my headphone amp (audio gd nfb 11.28)
i also have 6.3mm to 3.5mm adapter from a akg 371, the problem is that with this adapter i hear half sound on the xiaomi earphone (i also have another xiaomi earphones and same thing), and if connect to microusb the anc adapter i hear full sound, but with a background rustle.
i don't understand if the problem is an incompatibility wity my amp, or the adapter is the problem
what do you think?

You can bet there's nothing wrong with the adaptor.
You can confirm that - if your AKGs play to both sides via the adaptor, it's OK.

really?

 

[Al ears]

really?

Yes.
The adapter is good for the right sort of 3.5mm connector, unfortunately yours is a TRRS type because your earphones have a microphone.
Your earphones cannot pass a stereo signal when used with that adaptor, as far as I am aware.

 

[djsolidsnake86]

Yes.

i think there is someting strange in the adapter, if i insert half to the amp, it sound better
and if i recharge the anc module, it sound good but with the background noise

Does the adaptor work perfectly (with all fully plugged in) when used with your AKG or any other standard headphones?

If the answer is yes, how can there be anything wrong with it?

yours is a TRRS type because your earphones have a microphone.

That explains your issue.
The adaptor is a 3-pole connector.
Your plug is a 4-pole connector.

Your adaptor is not faulty - it's just not suitable for the TRRS plug.

Checkout the user guide of your headphones - see what it says about connection to standard (3-pole TRS) audio amplifiers.

TRS stands for Tip, Ring, Sleeve.
Compare your plug to the AKG one, you'll see it has an extra ring.

No, it will not work

are you sure? so what adapter can i buy for those earphones?

 

[Gray]

the akg plug has 2 black lines, the xiaomi plug has 3 black lines

Yes, the black lines are plastic insulation between the metal bits, which are the contacts (or poles) - 3 on a 'normal' plug, 4 on yours.

this with a 6.3 to 3.5 adapter?

are you sure? so what adapter can i buy for those earphones?

We're 100% sure. That is a wired version of the solid adaptor that you've got.
You need to check your instruction manual.
It will (certainly should) tell you how to connect your plug to audio amplifiers.

By that I mean it will tell you what adaptor to use.

No, that won't help you.
Your instruction manual holds your solution

in the manual there is nothing

why won't help? is a trss splitter for earphones that have microphone!

That will allow 2 feeds from 1 plug......but the one plug is wrong for your purpose of connecting to a headphone amplifier.

That's more like it

The socket on that has the necessary 4 poles for your plug.

If you go for that one, you might well find that the plugs come with insulating sleeves - so that the unused plug remains covered.......there will be instructions with that one.
