Thanks, everyone!
I've narrowed my results down to a couple in-ears:
H2O Audio TR1-BK H2O Audio Trax Custom Fit Sport Headphones (Black)

Sennheiser MM30i Headphones

JVC HAFXC80 Black Series In-Ear Carbon Headphones
Anyone suggestions between these three which one I should pick?
(I've heard good things about design for the H2O Audio Trax, but I'm unsure of sound quality. It MIGHT be just consumer-oriented sound quality. Does anyone know?)
(The Sennheiser MM30i fits almost all of my favorable characteristics for an in-ear. Remote, mic, sound quality, but I've heard Sennheisers like these that have the design or look like the CX300s are not good for sports / athletic activities.any Can anyone justify / verify this point?)
(From reviews online, I've heard good things about the HAFXC80s, but I've also heard that there's barely any bass at all. Also, I've heard that the cord is a little think to be comfortable for use in sports and the such. But hey, their price is eye-catching, as does their design. Advice?)
