Update: The headline deal on the Sennheiser HD1 Wireless has expired since this article was first published. The original article is below.

Original story: Greetings, Arsians! Courtesy of our friends at TechBargains, we have another round of deals to share. Today’s list is led by a deal on Sennheiser’s HD1 Wireless noise-cancelling headphones, which are down to an all-time low of $280 on Amazon.

These headphones used to normally retail for $500, dropped closer to $400 this year, and have fluctuated in the $300-340 range over the past few weeks. At $280, they’re still expensive, but that money gets you a pair of decidedly high-end cans. The retro design is comfortable and well-padded, and while their noise cancellation isn’t as strong as Bose’s QuietComfort series—and can’t be turned off—it’s still capable enough to block out most noisy environments.
