I usually use my ipod when I'm on the move, so it was a big hassle untangling the headphone cords. The tetran makes it really easy to remember to keep the cords organized. If I need to break out the headphones in a hurry, it's very easy to plug in the end and "yo-yo" the tetran for quick deployment (and a little fun). You get some strange looks at first, but it is totally worth getting to save time and energy.
