Hi...
first of all, sorry for my bad english...

ops:
I have some listening problems, but they aren't made by the earphones... it can be a firmware problem?
How can i do to know my player info to get the right firmware?
The infos in my "Settings" are:
Fw: 6207k8x_V3.2
Date: 2007/04/03
Core: 9.0.50
Date: 2006/01/11
thanks!
