Hello,
I've been using the fiio fh1 iem for almost a year since they were released here in India. I was more than satisfied with the sound quality and tuning of the sound signature of this particular set. I also use fiio ex1, x3 2nd gen and E07k dac presently.
Recently I lost the fh1 and purchased second copy of the same from fiio.co.in 1week back. I was and still very much surprised with the sound quality of this particular iem. It has too much sibilance in the high, sometimes it becoming unbearable. Used both type of tips, also my other tips including comply foams ones. Used it with different source like x3 ii, pc with foober and dragonfly black v1. 5, mobile usb audio player but availed no improvement. I'm fearing something is seriously not right here. The iem itself working perfectly but the harsh sibilance is not something i know in this iem. Is there any significant changes or tuning done between first and second generation of fh1 iem? Or i should contact fiio.co.in for potential replacement unit?
Kindly help.
Regards.
