Koyota-Up via eBay offers the Mini Bluetooth 4.0 In-Ear Headset in White for $4.40 with free shipping. (Black and beige are available for pennies more.) That's the lowest total price we could find by $5, excluding the mention below. It features a frequency response of 20Hz to 20kHz, and is compatible with most Bluetooth-enabled devices.
