What is the off chance that they actually improve especially in the mid range with what the dr ordered IF it was one or two people I would dismiss this burn in. But not only myself, dweaver but cute just mentioned it as well as Flysweep and very soon Eric as well. What is the chance that all of us are just experiencing brain burn in.. I still think your pair has not changed much but mine have. They don't have scooped out mid section like how I also heard them from open box any longer.
Listening to these on normal volume levels I don't think will work at all. But that is how I hear my pair. I don't doubt yours still have the scooped mids. It will be like that for a very long time if no burn in is happening. It doesn't damage anything. It just makes them sound better. Mine I can say has a very nice balance now actually. Better than most earphones I have heard. Bass has improved greatly too. All of it improves imo. Even if this improves 1% of what they are on open box. Isn't that 1% worth getting on these? I think so. I suppose we all have our "break in" method we all use so I am just mentioning what has been working for the guys that actually do this. No harm in trying it is my point.
One of the biggest changes IMO, with agressive burn in, is how the vocals have moved closer to the listening postition, quite so on good clean recordings. I also like how backup vocals on the FXD80 can be pinpointed in their own separate space. I can sense a lot of instraments with more detail, harp tone and clarity is very good. As a whole all instraments are there in quality! Any one in itself may be better on other IEM's, but as a whole, highs inparticular excel, where many other IEM's, not so good!
