They also hacked volume+pause controls onto the jack using flaky impedance tricks. I've had bad luck getting those controls working with TRRS extension cables.

People also use active noise-cancelling headphones that require their own battery.
I'm a bit nervous about the transition away from the classic 3.5 jack, especially since it looks like it'll probably be a standards war between the Apple and Android worlds. There are, however, some nice potential advantages.
- oasisbob 10y ago> I've had bad luck getting those controls working with TRRS extension cables. Ugh. That. A tip: always ensure that the extension cable is attached to the auxiliary device (eg headset) first. One of those flaky impedance tricks is to try and detect the microphone through it's impedance when the TRRS jack senses a plug. If you plug the extension cable in first, the device detects the plug in the jack, can't detect the microphone (or whatever other magical device it's looking for - like volume controls), and disables anything it doesn't detect until the plug is removed. ( At least that's how my Macbook works. )
