Audio Features
The Pandora has a high quality Digital to Analogue Converter (DAC). The sound signal from the processor is passed to an analogue amplifier, and at this point a signal from the volume control wheel is applied (so the OS has no visibility of the volume wheel, you have a final physical control over the volume). There is a built in microphone (on the right hinge), and a multi-terminal 3.5mm jack. Plugging in to the jack will disconnect the internal speakers. Note that ipod specific headphones use a different pin-out and are not compatible with the Pandora. Normal stereo headphones are compatible.
This jack input allows to plug a headphone + microphone headset (4 pins 3.5mm jack). See Pandora Hackers Manual page 18.
