if you want full range single driver then etymotic is should to better by the way i am not a fan of etymotic because there are no soundstage and little bass and they are uncomfortable. they make a compromise extremely accurately over comfort, soundstage,bass. why do want multiple drive is because they sound better because they a driver assign to a specific frequency thank to great crossover well thank klipsch making exclusive stuff they kill dual driver. plus multiple driver has better bass control.
