Summary: Best for the money, and then some.
Comment: I've compared these ear buds to Shure e2c's, ($50-60), and Creative Zen Auravana's, ($60-100), and found them better than the Shure's and almost as good as the Auravana's in certain ways, and better in other ways, (the bass on the Auravana's is too thumping, and cable noise is worse than the Koss). They're just plain astounding - especially for the money. If you want to buy something that beats all three, get the Creative EP-830's. Incredible sound that just barely beats these little Koss buds - but they're $50. For the money, the Koss can't be beat, period.

Summary: This is my second pair and the left ear plug goes out. Beware!
Comment: I have bought these before and had the left ear plug go out after 5 months. Koss has a lifetime replacement guarantee so i returned them and after 7 months with my new ones the same thing happened. For the price its not bad but be warned you get what you pay for.

Summary: Great introduction to in-ear monitors
Comment: I've been using Koss headphones for decades and the Plug continues to deliver that traditional "Koss" sound. The Plug is an inexpensive way to try get into the "in-ear" monitor area of headphones. They are comfortable to wear and deliver killer bass along with great mids and highs. I bought these for my son because he won't use anything else, including a pair of $400 Shure monitors I offered him. Give 'em a try. For $10, you can't go wrong.
One complaint though. Koss products are almost impossible to buy in Canada. Sure would like to see them establish a retail presence here again.

Summary: Very good headphones for the price
Comment: I've bought these headphones recently and I'm very satisfied. As a drummer I needed some in-ear monitoring headphones and I got stuck with these. Very comfortable for my ears (soft cushions) and it dampens surroundings very much which is exactly what I wanted. The sound is good, not excellent but like I said, I use it only when I play. Highly recommended.
