I have the same problem here with my K2 #01181 since 2 or 3 months. The rig is ongoing in 
use, with plug in and pull out the headphone all along. But I thing is not to be depending 
on the number of plug-ins and pull-outs. Maybe the spring steel inside the jack will be 
softer/lazier or the plastic material of the housing of the jack will lose it's softener 
and do not hold tight, so the contacts do no longer close. I have noticed, it is not the 
full sound intensity which I can hear with a pluged-in headphone from the speaker. As the 
only one solution I see is to change the jack itself.
