A hat specifically used to keep the Xbox Live headset to your ear while playing Halo 2 after the clip on it has broken and can no longer snap onto the headband. Mostly required due to the fact of poor design on Microsoft's part, why they made it in two parts is still a mystery. Thankfully they corrected their mistake with the 360 headset. Beanies work the best by far.
