Summary: For $10 dollars, you can't expect much. These ear-buds surpass the expectation. They block out a lot of background noise, they are also quite comfortable. I have finicky ears that get sour with a lot of ear buds (especially with the older Apple ear buds), but these don't do that. They also stay in very nicely unlike skull candy (I've never been able to got those to stay in). I've had these for over a year and they still are doing great.
Summary: I have been using marshmallows for several years now. The best for in the ear headphones. They sound great. The ear pieces conform to your ear canal. They are light weight. And they are definitely less expensive here than in a bix box.
Summary: I bought these headphones about three months ago. The headphones I've always used in the past are Skullcandy 50/50 earbuds, which for retail run about $20 more than these. Sound-wise, they sound great with the one exception that the bass isn't quite as pronounced in these as the 50/50 ones, even after finding a correct size. My real problem with these are the squishy buds themselves.
Summary: I bought them for my wife and she says they work as advertised. She is very pleased with them. She says that they are pleasent to use, as the reason for buying them was the ones she was using were not comfortable.
