These earphones provide amazing clarity and richness in sound.  Unfortunately the good qualities are overwhelmed by the hugely exaggerated treble.

I carried out 72 hours of break-in with loud rock music.  24 hours is supposed to reduce the treble.  I also made sure the earphones seal well to my ear, which is also recommended.  It did improve the exaggerated treble somewhat, but not nearly enough.  Using Treble Reducer on my iPod helps, but it distorts the sound in a different way.

Listening to electronic music or amplified rock sounds too bright, but tolerable.  Jazz is overly bright, but tolerable.  However classical music is just wrong, quite unnatural sounding.  Orchestral music sounds thin, tinny and unpleasant.

Too bad.  I had high hopes for these well-made little devices.
