Hearing all the angst about the L3P reminds me of my first big expensive buys. I bought the Sennheiser IE8 and they sounded like garbage OOB it took in excess of 100hrs of burn in before they opened up and sounded good.
I would only listen for a few minutes every day after playing music non stop for 24 hours. After 4 solid days of this crazy process and them sounding god awful each day I was ready to give the damn things away. The suddenly I put them on and played the exact same track and wham they sounded open and wonderful.
Being a typical headphone junky the siren call of something new eventually made me sell them and try something different but I never forgot that lesson on patience
