Decent Earbuds on the Cheap

The Sennheiser MX65 is pretty decent. It has an extra "plug" that goes into the notch above the ear canal that keeps it tight in your ear. No falling out and a better seal. $50.

Etymotic and Grados. Have experience with both. Comfortable and great sound provided you use the correct ear plug for your ears...otherwise you lose bass and more outside noise comes in.

I decided on a set of Altec Lansing UHP 326. I'll post a review next week.
