Koss The Plug Earbuds Consumer Headphones

i've had a pair of these for a year now, and i've lost all the plugs that fit my ear.
the plugs that did fit needed to be replaced anyways, from numerous times "smooshing" them to get them in, they started to fall to pieces, sometimes leaving little black pieces of foam in my ear... not good.

if you want a great sounding portable set, these offer great sound, and are very isolating (which i prefer).

im still looking for a pair that sound as good as these without the hassle of trying to put them in, and getting them to stay in my ear properly while working out.
