The goal: a way to wrap up cords (headphones, power, etc.) without ties or Velcro straps that's fast, doesn't come undone, and is quick to undo. Here's one method, any better suggestions?

Step 1: Make Figure 8 Loops...
Leave about 2 figure 8 loops of wire left to wrap around the middle.
Step 2: Wrap Around the Middle a Couple Times
The key to this whole method is crossing the wire over itself in the first middle wrap. Otherwise the whole thing will easily come undone.
