THE BEAT DIDN'T STOP, WHY SHOULD YOU?
You need to listen to your soundtrack because a lot goes on in your day. Cables should not get in the way. Spül it, and keep rocking.
Let's set the scene for you. You've hit your stride. Everything is going well. Suddenly, *YANK*, you accidentally pull your earphones out. And you are sad. Spül allows you to shorten the length of your earbud or headphone cables to whatever length you desire at any time, problem solved.
Spül stores and stops your earbuds from tangling when sticking them in your pocket, making it faster for you to start the party when you need to.
