Amazon offers Prime members the Quirky Wrapster POP Headphone Wrappers in Grey, White, or Teal for 99 cents with free shipping. (Non-members can spend $35 to qualify for free shipping; otherwise, it adds $6.23.) That's the lowest total price we could find by $4. It's designed to keep earbuds tangle-free and doubles as a stand for iPhones in landscape mode.
