Pros: Oval tip is not just a marketing feature - it really does increase comfort and fit. The sound is good and with quite adequate Bass unless you're into Hip-Hop, I guess. The more natural bass of classical music comes out just fine.

Cons: None

Overall Review: For those that have trouble keeping them in, I'd suggest rotating them 180 degrees and looping the wire behind the ear. Then move the slide up to make them comfortably snug. This provides a good flexible strain isolation from donw the cable.
