Summary: Handy to have those replacements
Comment: I bought these to go with the Koss sparkplugs--obviously!
Koss SPARKPLUG - Stereo In Ear Ear Plugs The sound quality of the ear buds themselves isn't great, as I say in my review, but I'm not an audiophile and being able to get replacements easily is a big plus. But look at the enlarged picture of the product first. You'll see that only four of the six sets are the conventional type, two sets smallish and two sets larger. The other two sets look a lot different. I tried them briefly and they seem to cancel more noise than the other kind. The material is also very soft and seems really comfortable, but they're a bit sticky feeling and get a little funky from being in your ear. But for this price to have three types of cushions to choose from is great.

Summary: I was looking forward to using these
Comment: I have the Koss Plug earpiece because they block outside noises but unfortunately it was hard to use them since they were too big to fit in my ear and they kept falling out during my workouts. So when I saw these I was ecstatic and even shouted with glee because I figured that one or more of those sets had to fit my ear right??....well my jubilation was short lived once I tried to use even the smallest cushion because it was still too big for my ear. I rolled and pinched them between my fingers as instructed but they just wouldn't stay in. So I gave them to my husband and of course they fit him. *sigh*

Summary: These are amazing.
Comment: I bought these as replacement cushions for my KOSS ear buds, BUT the replacements were so much more comfortable that I swapped the originals for the the replacements immediately. These are well worth the price and I am going to order a couple more sets right away.
