one thing to seriously consider for in-ear buds is comfort. doesnt matter how good the headphones sound if they bother your ears or fall out when you walk.
I use a 24 dollar pair of panasonic buds just because of how well they fit my ear. The sound is pretty good, bass isnt the best but I wouldnt wanna wear any other buds cuz I havent found anything close to as comfortable as these ones.
