A vented tip for in-the-ear headphones has a core portion to be mounted to a sound output tube of an in-the-ear earphone and a flange portion extending outward from and surrounding the core portion. The vented tip has a) an outer portion formed in the flange portion that is to be in contact with, and thereby form a seal with, a user's ear canal, and b) an inner portion spaced inwards from the outer portion to thereby not form the seal with the user's ear canal. The inner portion has a calibrated perforation or hole formed therein. Other embodiments that may help reduce bone conduction effects are also described and claimed.
