In other words- you could have a device with the same TRRS Pinout as apple products- but the headset wont work because the resistances (ohms) of the headphones send signals that your phone is not allowed to interpret into the correct actions (since apple patented these)įirst- to the admins- not sure if you can combine all threads under this. This is why- if you try a set of newer iPhone earbuds on the GSIII- as I have- the center button does nothing, but yet the volume up and volume down both pause tracks, and allow you to skip them!!Īdditionally, Apple has patents on their TRRS connection- in fact on the resistances (the actual ohm resistance in-line on the controls- not to get scientific or anything ) so that the headphones are designed to work only with Apple products. The way that volume is increased/decreased occurs by sending signals down the Mic channel. The way that songs are skipped (forwards, backwards, and pause) occurs by sending signals down the ground channel (when you tap the button it shoots an electrical signal that the phone will pick up and interpret). This is why many apple headsets will not work with android, because the last 2 connections, for Mic and Ground are switched.

The original TRRS configuration was created by Nokia and has a pinout of Left Audio, Right Audio, Mic, Ground.Īpple came along and changed their pinout to Left Audio, Right Audio, Ground, Mic. The pinout for these connections is: Left Audio, Right Audio, Ground.Ĭonnection types for headphones with a mic (and newer ones with volume control) are configured inġ. The standard 3.5mm headphones (no in-line controls on the cable) use the configuration of (from left to right) In all of the following explanations- imagine that the tip of the plug is facing left.
