??? The K712 is the same basic design as the k701 and k702 that have been around for many years. I've owned K702's for over 5 years and I've never heard the "squeaks and creaks" you're describing. If you could be more specific as to which plastic parts are rubbing the wrong way it would help us understand your discomfiture.
Apologies for being so vague. This video accurately reflects the sorts of noises that I am hearing https://www.youtube.com/watch?v=N2X-kjgZXu4 . Although I have never been heavy handed with my pair and I have always taken very good care. I have now looked at the service document for part names. The bit on the side that I am referring to is called the 'slider'. There is a black 'outer slider' and a translucent 'inner slider' that meet the leather 'headband' and they slide along the 'outer headband' and against a inner black part (for which there is no part name) which has the serial number printed on it. From what I can see and hear it is these sliders that creak as the headband expands and contracts and in particular when the inner and outer sliders slide up and down the orange outer headband. Its very obvious if for example I try and readjust the headphones whilst I am wearing them. The second bit I was trying to describe is called the 'disk'. The 'disk' pivots backwards and forwards against the 'ring' for a better fit I imagine. As the 'disk' moves backwards and forwards the plastic rubs against the 'ring' causing a very unpleasant sound. This becomes apparent especially when I open my mouth or move my jaw from side to side - for whatever reason. I hope you now have a better idea of what I'm talking about.
I have spoken to the official UK AKG distributer and they have advised me that all AKG 7xx are susceptible to some noise and that I should try a silicon based lubricant. Well Ive lubricated a bunch of parts and its still borderline unbearable.
