Just wanted to share my favorite headband to wear during winter runs. This is the most comfortable headband I've ever owned. It covers my ears perfectly even when I'm wearing my earbuds. It stays in place and it's reversible. Unfortunately you can only find this color on ebay and it's way over priced. The mint and black colored one is on sale at Lululemon's website under the "We Made Too Much" tab.
Here is what the Lululemon website say's about their product:
