Einleitung

I just recently performed a teardown of the Apple Lightning Earphones to see if the stock Earphones could be replaced/modded for different drivers. I plan to use the lightning adapter and then change the earphones/cabling to something better.

    • As you can see, there are 5 wires going into the mic/volume control. The red/red stripe are passed through to the right earphone, while the other 3 (red, green, & orange) are twisted together and wired for the mic/volume controls.

@oldturkey03 The device has 7 wires just like the adapter. 2 for the left earphone, 2 for the right earphone, and 3 for the mic/volume control.

@masongdowell you are absolutely right. Sorry about the miscount. Old eyes and not enough sleep :-)

It seems like the EarPods maintain discrete ground wires for all 3 signal lines out of the amp, as well as the common ground, but combines them for any headphones plugged into the adapter jack. Does this mean the Lightning EarPods are providing balanced lines throughout? Whereas the adaptor is an unbalanced converter?

These 7 wires still have to be resolved onto four conductors of the TRRS jack of the adapter. So that means that of the four conductors, L, R, Mic, & Ground, only the L, R & Mic are discreet. The ground sleeve is where the L-, R-, & Mic-, must converge. So essentially 4 out of 7 wires are common ground in this adapter.

So what would happen if I cut off the EarPods, and took the 4 wires and connected them to a TRS jack for attaching a pair of basic stereo headphones with TRS plug? I'd combine both negative L & R wires to the common ground. Basically converting a basic headphone into one with a remote and Mic. Would this result in any loss of quality?

This also makes me think the amp in the Lightning adapter is compromised to provide headphone and line level output, while the Earbuds probably have a custom amp for providing optimal headphone output. That may be why there are two different chips.
