I know there are many postings on "burn in", but there seems to be a fair deal of contradiction on this topic. As a budding headphone enthusiast, what exactly do I need to burn in? Or is it simply not necessary?   Thanks for your help! AO

Hey everyone,   I'm just getting started with high-end headphones, looking forward to it!   Just picked up a pair of slightly used Senn 595's (120 Ohm) for $125.00 shipped. Seems like a decent deal, right?
