I have a pair of hd 270 headphone, made by sennheiser. the headphones are built to allow the disconnect of the plug and the phones themselves. after repeated use (and connecting and disconnecting) the phones and plug, it seems that there is some static coming from the plug and phones. i attribute this as a ''wear'' situation. i want to fix them myself, but do not know how to dismantle the phones without breaking them. anyone out there with a similar problem/solution. any help would be much appreciated.

Thanks.
