Staples offers a selection of Panasonic In-Ear Headphones in six colors, model no. RPHJE120, for $5.49. Plus, Staples Rewards members bag free shipping. (Not a member? It's free to sign up; otherwise, shipping is $9.95. In-store pickup is also available.) That's the lowest total price we could find by a buck in any color, although we saw them in silver for $4 less via rebate in June. They feature three pairs of ear tips and a 3.5mm plug.
