World Wide Stereo offers the dB Logic EP-100 Earbud Headphones in Red or Pink for $12.97. Better yet, add two pairs to your cart ($25.94 total) and coupon code "SD888" cuts them to $8.88. With free shipping, that's $4.44 per pair and the lowest per-unit price we've seen. (We saw one pair for $6 in October.) They feature three sizes of eartips, a gold-plated 3.5mm connector, and 20Hz to 20kHz frequency response.
