Just got the IE7!! I was definitely impressed at the sound and comfort out of the box. Great lows (bass could be tighter), good mids but lacking highs. I turned "treble boost" on on my mp3 player which definitely helped. My hope is that with time (burn-in), the highs will come out and the bass will tighten.
But the good (and most important) thing is, I already like them over my UE Super .fi 5 Pro! So any ideas as to how I should burn em in? Pink noise? Bass tests? or just allow it to cycle through my library at random? Which is the best to 1) Bring out the highs and 2) tighten the bass?
