Staples offers the Sony ZX Series Stereo Headphones in Black or White, model no. MDR-ZX110, for $9.99. Plus, Staples Rewards members receive free shipping. (Not a member? It's free to join.) That's the lowest total price we could find by $4, although we saw them for $2 less in December. They feature 30mm drivers, swivel design, and tangle free cord.
