Hi Steven,

i'm sorry, Steven is right.

The headset-plug seem's to have a weird configuration.

____________
___|___|___|__>
  1    2    3    4


1: GND
2: Channel left (right)
3: Channel right (left)
4: mic / switch

Correct me if I'm wrong, but this is incompatible to common stereo jacks.

regards, Felix
