Bose IE2

Pros: Comfortable
Great sound replication (mid's, high's, and low's)

Cons: There are none!!

Summary: In my opinion these are the best earbuds I've ever owned. True audiophiles know that Bose is the best in the business for great sound. The bass is rich without being overpowering, like someone driving around with their subs turned WAY too high, and the mid's and high's are crisp with just the right amount of treble. Not one genre of music sounds bad played through these. I own both the IE2's and the Klipsch S4's, and hands down the Bose wins every category. With the S4's the bass is great but other frequencies are drowned out due to very very low treble levels, so sound reproduction just isn't very pleasing. While not noise-isolating, if you use the best sized cup for your ears you shouldn't have any issues with outside noise. For $70-$80 the Klipsch (for me anyways) just don't perform for the money. These IE2's, though, are well worth the price though. You always know what you're gonna get with Bose.
