Playback magazine (equipment reviewers are from The Absolute Sound [TAS] & The Perfect Vision [TPV]) reviews "Killer Earbuds" in this month's issue:

They highly recommend the
Skullcandy Titan ($50), calling them, "one of the sweetest values in today's market" and "arguably Skullcandy's best-sounding earbud." They even go as far to say, "the Titans are hands down the best budget in-ear headphones we've yet heard."
Positive attributes of these earbuds are: "near-neutral tonal balance, good dynamic punch, and an unexpectedly big helping of sonic subtlety and detailespecially in the midrange". The one minor flaw, which some listeners (especially non-audiophiles) might regard as a serious plus, is a hint of excess bass richness. So the bass may appear slightly overripe when critically listening in a quiet environment, but would actually be beneficial in environments that have lots of low-frequency background noise (e.g. moving cars, airplanes, etc).
As the reviewers (from TAS) are known as being highly critical audiophiles, I would regard this review with more merit than those by other consumer electronics publications.
