Sorry if this has been discuss before, I did a search and there wasn't any thread that discuss about this, or I could have mistaken it.
 
I've brought UE TF10 for like 3 months and over time, the highs seems to be flatten. I need to adjust my Cowon J3 EQ settings to get back the crisp highs. Anyone has any experience on this matter, is this normal?

very like it's due to wax build up in the filters. Happened to my TF10s as well and after cleaning the filters issue was immediately resolved.

Hmm, doesn't seem to have wax built up on both of the sound holes, but it seems like there's a green/yellow foam on the left hole and none on the right hole. It has been there ever since the beginning.

Wax build up in your ears?  And, not I'm not joking.  I need to get a cleaning tune-up once a year.
