Comment(by Quozl):

 XO-1 vs XO-1.5, powered off with battery removed. Mono or stereo 3.5mm
 plug connected to a digital multimeter in resistance mode.

  * on XO-1.5 the mono plug shorts (0.5 ohms) once it is fully inserted,
 the shorting occurs in the last millimetre of travel.

  * on XO-1 the same does not occur.

 Dimensions were compared with calipers which had a limit of reading of
 0.02mm.

 ||'''plug'''||'''length'''||'''tip isolation'''||
 ||mono||14.88mm||2.16mm||
 ||stereo||14.14mm||1.26mm||
