VMInnovations via eBay offers the refurbished Sennheiser HD428 DJ Stereo Headphones for $24.99 with free shipping. That's tied with last month's mention as the lowest total price we've seen for these headphones. (It's $30 under the best deal we could find a new pair.) They feature an 18Hz to 22kHz frequency response, noise-isolation earcups, 3.5mm plug, 1/4" adapter, and more.

Note: A 90-Day VMInnovations warranty applies.
