Most headphones are clearly designed for men. There aren't that many that appeal to women. Sony has tried to rectify this problem with their MDR-EX33 series of in-ear headphones. They come in a variety of fashionable colors.
These headphones come in six different colors to add a little more bling to your style. They also come with a nice and comfortable soft rubber padding, surrounding a firm central inner liner. They are available in Japan for $22. For that price, you can purchase more than one color to mix and match.
