Cheap. Reliable. Affordable. Nuff Said' lol.
But seriously... These ear buds are the best. They are cheap, and I have absolutely punished them with heavy daily use as a full time game developer (who listens to a LOT of music ranging in every direction while working) and art student at night. They have seen just about everything when it comes to wear and tear and I still am using the same pair after 6months and going very strong. They have excellent bass for in-ear, especially the price with free shipping. I also have HD280s (also GREAT headphones).
I seriously will never look farther for another model than these puppies. A definite recommended buy, especially with all 257 great reviews on the egg. They are for sale with free shipping, like 50% off! Grab em while they are in stock!
Keep us posted on your purchase, always fun to see new toys!
EDIT: Pretty good bass for me, I listen to a lot of electronic music, with heavy bass and they do quite well for the price
