My HE-400's are on their way and I'd like to know beforehand what should I use for burn in?
Does it matter what you use or can you just use them normally until "x" amount of time?
Lot's of different opinions on this. I start out just letting music play on random on low volume, increasing the volume every couple hours over the next 8 hours until it is at a listening level. Then I run some pink noise overnight at a low to moderate volume. I do music during the day, pink noise at night for a few days.
Start enjoying them right away!
