Earpollution D33 earbuds are not only noise isolating headphones, but also offer a snug secure fit and rich deep sound. Each package includes 3 ear fits and a convenient travel case. The metallic colors and PVC Radioactive patch are stylish and easily recognized as part of the ifrogz family. Available in multiple colors of black, green, orange or pink you're sure to find headphones that matches the look you want. If you're looking for earbuds that you use with a shuffle (clip-on style) at the gym or on the run then we recommend the short cord earbud model, appropriately called shorties. They are too short for use with an armband, so if you're using an armband with a nano you'll want to get these regular length ones.
