Looks great and great, too!

For being low-cost headphones, they sound way better than ones from better known manufacturers, particularly at the < $30 price point. One thing to know is these like a little more volume to power the drivers. My only complaint is the wires are a little thin to the point where they seem fragile. BTW, the mic is pretty decent.

Very basic, fit comfortably, exactly what I asked for

Really lightweight and a little cheap-feeling, but exactly what I was expecting for the price. Sound quality is great and they feel comfortable on my big ol' noggin, plus I think it's fun how many colors these ones come in. I keep having to replace my headphones/wired earbuds after only like a year of use, and I heard good things about Koss online so I'm hoping these will last for a decent amount of time -- though, these were on the cheaper end of what they offer, so I don't know that I can fault them if they do wear down relatively quickly. If this pair lasts 2 years before breaking down, I'll totally feel comfortable investing in one of their more expensive headphones.
