I've all but abandoned all my IEMs in favor of these babies.. I can't imagine life without them. I carry them with me everywhere I go, and then take them home and plug them into my computer when I'm playing games. I use them for everything now and I can't stop. I've actually stopped obsessively reading head-fi lately because I feel like I have all I need already.
I don't think they were defective as shortly after I unboxed them they sounded as everybody described them to sound as new. After 10 minutes or so of use, they started to clear up a bit and have that wonderful focus on vocals.
It was only after a bunch of burn-in at high, but not earth-shaking, volume that everything turned really muddy and indistinct.
I burned them in two ways: several overnight sessions with pink/white/brown burn-in track on repeat at levels slightly above what I could stand for more than 10 seconds (loud, but not loud enough to damage the drivers, IMO).
I also had a number of overnight sessions playing my local club mix station, lots of bass. This time, same kind of volume, but there were a couple of nights where the treble may have been distorting a little bit.
I don't know if this would have been enough to damage the drivers or not.
I'm going to continue playing with them to see if they change, maybe with more burn-in, but at a very moderate level this time.
