It's called brain burn in.
yea it does
to each his own, but for me the best burn in is just listen to it, the play some music and shove in a draw is good to but DO NOT play music louder than what'd you listen to. I'm a big burn in beliver BUT I'm not a RUN PINK NOISE FOR 8 hours kinda guy... BOOO LAME, just play regular music. Trust me my dt 880 250's are around like 400 maybe 500 hours and I'm still going... wait WHAT haven't heard that before! recently they've had a nice thick bottom end with vocals that I never noticed before [those upper bass and lower mids are sounding REAL nice, great push and warmth] so even if u listend to your dj 100's EVERY day with the same I dunno 100 songs, after a week or maybe less you'd notice something different... it would just hit you...
