I tried to get over the long standing problem that i have 3 iPhone headphones. Fully Audio functional but the Volume, Mic and the Button doesn’t work. Bader i have to pull out the headphone to if somebody calls me. So i checked the cabling and found a adapter on ebay. this one
So i ordered 3 and got them today. But else than expected it doesn’t work. Actualy its extreamly weard and i wol like to know what you think how thats possible…
If i listen to audio it works but sounds weard like phaseing, if i then press the button it sounds good as long as i hold it. Volume and mic doesn’t work. So i thaught the adapter might not be what they say it is.
so i cut one open and measured it. and its exactly what i expected.
Tip to shaft pin1-4 its like this: 1-1, 2-2, 3-4, 4-3.
So im puzzled about why.
If Fairphone says its a CTIA connector and the iPhone Headphone is also a CTIA as i now read here then why does the Mic not work? At least the mic should do its job, not?
