There's a four-ring 2.5mm stereo jack which provides connectivity to old-fashioned wired headsets.
The headsets used by Motorola smartphones (A780,A1200, ...) and the V-360 have a compatible configuration.
Neo FreeRunner

1(base): GND
2: right out
3: left out
4(tip): mic + HOLD-button(press:short to GND)
Neo 1973
Pinout: [1]
base = ground
speaker left (internal impedance 33R) to ground. (+jackinsert detection)
speaker right (internal impedance 33R) to ground.
tip = mic electret condenser type, to ground.
bias (power for mic) 2K2 from +3.3v(wolfson codec)
(+HoldButton shortcircuit to ground)
