Ever walked down the street with your earphones in your ears and then suddenly, one of them pops out of your ear. As you try to pull it back into your ear, the other ear drips and that earphone falls too. Well, these are different in that instead of going into your earlobe they vibrate music from your cartilage and into your ear. These are really cool because I always have a hard time keeping normal earphones in my ears and didn’t want to have to carry around large headphones for my little device. These are great for people who want to hear music without interruptions, well, not entirely true. These don’t drown out the sound around you so you’ll still hear outside noises.
