I'm sure they're just as nice - but not tried one, makes me think of my Thunder 1A which has a series parallel switch - thins the sound out for a jazzier feel - works well on the Westone - not tried a Precision though.[/quote]
The S1 does just that;it thins out the sound.We have all suffered boomy bottoms I'm sure!! This solves it.
