As one of its daily deals, Daily Sale offers the Apple Earphones with Remote and Mic 2-Pack in White, model no. MB770G/B, for $8 with free shipping. At $4 each, that's the lowest total per-unit price we've seen and it's a current low by $9. (For further comparison, we saw just one for $6 in September.) These earphones feature a 3.5mm connector, in-line microphone, and 3-button remote.
