BigDeals via eBay offers the open-box Monster Beats by Dr. Dre Diddybeats In-Ear Headphones with ControlTalk in Black, White, or Pink for $39.99 with free shipping. That's the lowest total price we could find by $10, although we saw a new, factory-sealed pair for $5 less a month ago. They feature an in-line ControlTalk remote and multiple noise-isolating ear tips. Deal ends today.
