SE846 will have a very fast bass (decay and attack are about the fastest we ever tested) but the nozzle system is quite less practical than Roxanne's "inline bass dial" L/R control.
Not taking size in account, we sort them in this preference order:
1) W80
2) SE846
3) W60
W60 becomes an obvious choice for those with smaller ears.
Keep in mind Universal fit earphones are more and more being preferred over custom. Just start paying attention to concerts, TV journalists and high profile artists in general. The less "contact" between the "foreign object" (earpice) and your ear canal, the better. Customs require much more contact than necessary and ideal. And that's why you start seeing more and more manufacturers building $1,000 universal fit earphones.
