ts3a227e datasheet says typical key resistance is key1 50 Om key2 135 Om key3 240 Om key4 470 Om
The android headset specification expect buttons impedance: A (MEDIA) 0-70 Om D (VOICECOMMAND) 110-180 Om B (VOLUMEUP) 210-290 Om C (VOLUMEDOWN) 360-680 Om
Thus key mapping should be key1 - MEDIA key2 - VOICECOMMAND key3 - VOLUMEUP key3 - VOLUMEDOWN

These are correct. The initial mapping was based on a mislabeled, pre-production eval board. The new mapping was tested with the reference headsets.
