As one of its daily deals, A4C offers the refurbished Soul by Ludacris On-Ear Ultra Dynamic Headphones in Blue, model no. SL100, for $24.95 with free shipping. That's tied with our mention from five days ago, since expired, and the lowest total price we could find. (It's also $65 under the price of a new unit.) They feature full ear cup articulation, a protective case, and in-line mic. They're compatible with iPhone 4G and 3GS, iPad, and iPod. Deal ends today.

A 90-day A4C warranty applies.
