what do i use? well if i need a really cheap pair of in ears....
i like the gummy brand in-ear headphones since they are cheap and since they get gunked up i can replace them every other month. they arent really the best sounding but perfectly fine for the gym.
the ipod headphones are a bit better sounding but are more costly so i cannot just replace them as often.
for over the ear headphone listening at home or on the go i use a decent pair which you can get for about $100. there is no comparision.
