Whether you use an iPod or other MP3 player, you are certainly already familiar with the trouble of ear bud cords knotting up every single time you want to use them. That’s exactly Bluelounge has created POP, an easy to use cord winder. It simply suctions onto the back of your iPod to let you wrap and protect your cords. It’s that simple and safe. No more frustrating tangles or knots! POP grips to the iPod with a very strong suction bond. Even though the Nano and iPhone have slightly textured surfaces, we include a transparent sticker to create a smooth surface for improving the POP grip.
