I lost my expensive Sony earbuds and couldn't afford to replace them, so I chose these based on the reviews. They're pretty comfortable, the cord is a good length, and the sound is great for the price. I purchased these to use with my laptop in my school's library. They keep out the noises of everyone coughing and sniffling. I like to listen to classical music when I study, and the sound is very comparable to my expensive stereo system, and actually better than my desktop speakers on my home computer.
My ONLY complaint is that when you put the earbuds in, you can actually hear a loud clicking sound in your ears while you wait for the silicone to warm up and settle in. You might hear the same noise if you accidentally tug on the cord. Since I only use these while I'm sitting down and not overly active, I don't mind too much, but this might bother you if you want to use these earbuds while working out or moving around a lot. I also wish they would have marked a L and R on the earbuds, but I didn't take a star away for that; I solved that minor oversight with a Sharpie.
Overstock did a great job shipping these very quickly, and the item arrived well-protected and undamaged. I bought these during the $1 shipping special, and they were very fairly priced, so I give Overstock 5 stars.
