Monster Products via eBay offers the refurbished Monster Inspiration Active Over-Ear Headphones in Black, model no. 128917-50, for $99.93 with free shipping. That's $49 under our mention of a new pair from a week ago and the lowest total price we've seen for these headphones. (It's also $150 under the lowest price we could find for a new pair now.) They feature both Apple and universal ControlTalk cables, interchangeable headbands (two included), and protective travel case.

Note: Clear warranty information is not provided.

Update: Note that these headphones are noise-isolating, not noise-cancelling as we originally reported. We regret the error.
