hey beeman458, how where they before the burn in?
A bit harsh. As they're used, the music has smoothed out, with more extension into the bass and treble. I haven't used the bass control the IE8's come with as what ever the setting is on sounds perfectly fine.
How long do u plan to burn them in?
I don't have a plan other than to simply run music through them, recharge the battery of the MP3 player when the battery runs out of juice and then run more music through them. In between songs, due to something happening with the software, there's also white noise so it's a mix of sounds.
Are u using normal music?
That all depends on if you consider Simon and Garfunkel.....normal music.
