I am amazed that these are in production, they suck so bad. I did not realize that "in ear headphones" meant that you had to shove the ear piece into your ear as far as you can to get anything close to proper sound. The smallest buds were too large for my ears, so I would shove it in there (hardly seems like a good thing to do to your ears) and create a suction (even worse). I few minutes later, if I had managed not to touch the cord and release it from my ear, the suction would release and I had to start all over. I tried all of the suggestions I found on the internet (upside down, wrap the cord around your ear, turning the buds inside out). Nothing worked. These just suck. DO NOT BUY THEM. I will post a better option when I find one.
